Product Models

Arlyn High Resolution Balances and Scales are designed for lower-capacity applications that require very small displayed weight increments. Available models provide capacities from 200 g to 6,200 g, with readability as fine as 0.1 mg on selected models. This makes the line suitable for laboratories, quality-control departments and other controlled work areas where small samples and material changes must be clearly detected.

Quick answer: Choose a High Resolution Balance when your priority is milligram or sub-milligram readability at relatively low capacity in a stable environment. Choose an Ultra Precision Scale when you need fine measurement performance at higher industrial capacities, larger or custom platforms, greater durability, automation or broader native upgrade flexibility. When a High Resolution model provides the right weighing performance but you need a modern touchscreen and expanded data functions, a compatible balance can also be connected to the Arlyn UpScale Touchscreen through Third-Party Scale Integration.

These two product lines serve different weighing needs. The High Resolution line can display smaller increments than many Ultra Precision models, but it has a narrower range of capacities, physical configurations and native upgrade options. Ultra Precision scales provide a more versatile bridge between precision weighing and industrial process integration.

UpScale integration creates a useful third path. It allows customers to retain the fine readability and compact format of a compatible High Resolution Balance while adding an Arlyn touchscreen interface and selected advanced workflow functions. It does not change the balance’s capacity, readability, accuracy or underlying measurement technology.

When to Choose a High Resolution Balance

A High Resolution Balance is a strong choice when the sample is relatively light and the smallest meaningful weight change is measured in milligrams or fractions of a milligram. Typical applications include:

  • Laboratory sample preparation
  • Water and environmental testing
  • Small chemical or formulation measurements
  • Pharmaceutical and research work
  • Quality-control sampling
  • Small-component verification
  • Educational and university laboratories

The current High Resolution line includes models ranging from 200 g × 0.1 mg to 6,200 g × 10 mg. Select the model by considering both the maximum gross load and the smallest increment the process needs to display.

Do not choose a balance solely because it shows more decimal places. The container, sample and any accessories must remain within the scale’s capacity, while the operating environment must be stable enough to support sensitive measurements.

High Resolution vs. Ultra Precision Scales

“High resolution” and “Ultra Precision” should not be treated as interchangeable product descriptions. High Resolution Balances emphasize extremely fine readability at lower capacities. Arlyn Ultra Precision Scales emphasize industrial measurement performance, higher capacities and greater system versatility.

High Resolution Balance or Ultra Precision Scale?
Selection Factor High Resolution Balances Ultra Precision Scales
Primary advantage Very fine milligram or sub-milligram readability at low capacity Precision measurement across a much wider range of industrial capacities and platform sizes
Typical load Small laboratory samples and lightweight materials Ingredients, containers, components, drums and heavier industrial loads
Operating environment Stable indoor bench or laboratory environment Laboratories, production areas and more demanding industrial environments, subject to model specifications
Platform choices Compact balance formats intended for smaller items Bench, large-platform and custom configurations
Native connectivity RS-232 included; selected printer and Windows-interface options Broader options such as USB, Ethernet, Wi-Fi, serial interfaces, analog output and industrial protocols on compatible configurations
Touchscreen expansion A compatible balance can feed weight data to Arlyn UpScale through Third-Party Scale Integration UpScale can be selected as an integrated indicator on compatible Ultra Precision configurations
Automation Primarily measurement and basic data output; selected UpScale functions may be added through integration Can natively support setpoints, relays, batching, filling and process integration on compatible configurations
Mechanical customization Limited compared with the Ultra Precision product line Custom platforms, multi-scale systems and specialized configurations may be available
Best choice when The smallest displayed increment at low capacity is the main requirement Measurement performance must be combined with capacity, durability and industrial integration

Readability Is Not the Same as Accuracy

Readability is the smallest increment shown by the balance. For example, a readability of 0.1 mg means the display can change in increments of one-tenth of a milligram. Accuracy describes how closely a measured result agrees with the actual value under stated conditions.

A balance with finer readability does not automatically deliver a better result in every application. Repeatability, calibration, temperature, air currents, vibration, static electricity, sample handling and surface stability can all affect sensitive measurements.

When selecting a model, compare:

  • Maximum capacity
  • Readability
  • Specified accuracy
  • Repeatability and stability requirements
  • Calibration procedures
  • Operating-temperature range
  • Required communication and workflow features

Create a Stable Weighing Environment

High-resolution measurements are more sensitive to environmental disturbances than ordinary industrial weighing. For the most consistent results, place the balance on a rigid, level surface away from vibration, open windows, fans, ventilation outlets and frequently used doors.

Temperature changes, evaporation, moisture absorption and static charge can also influence results. Allow samples and containers to stabilize when the procedure requires it, and use an appropriate draft shield when air movement could affect the selected model.

A draft shield reduces interference from air currents. It should not be described as protection for the operator from hazardous chemicals or unstable materials. Hazardous samples require separate containment, ventilation and safety procedures established for the material and workplace.

Native Data Output and Available Options

Arlyn High Resolution Balances include RS-232 communication for connection to compatible computers, HMIs or printers. Selected printer and Windows-interface software options are also available.

Without an additional integration system, this product line is intentionally more focused than the Ultra Precision line. It does not natively provide the same range of touchscreen, wireless, industrial-network, setpoint, automation and custom-platform upgrades.

If RS-232 and basic printing meet the application’s requirements, the standard High Resolution configuration may be the simplest and most economical choice. If the weighing performance is correct but the operator or data workflow requires more functionality, UpScale integration can provide an expansion path.

Expand a High Resolution Balance with Arlyn UpScale

Arlyn’s Third-Party Scale Integration allows the Arlyn UpScale Touchscreen Indicator to connect to the data stream from a compatible existing scale display. The weight can then be shown on UpScale and passed through compatible UpScale feature modules.

Depending on the final configuration and options selected, this can provide access to functions such as:

  • A 7-inch color touchscreen interface
  • Custom fields for recording information with a weight
  • User management and time tracking
  • Checkweighing workflows
  • Barcode or QR-code scanning and printing
  • USB or network-based data logging
  • Google Spreadsheet data logging
  • Ethernet or Wi-Fi communication
  • Web API access
  • Remote weight monitoring through compatible services

What UpScale integration changes: It can expand the display, data-management and workflow capabilities available to a compatible High Resolution Balance.

What it does not change: It does not alter the balance’s load sensor, maximum capacity, readability, stated accuracy, physical platform or environmental suitability. It also does not turn the balance into an Ultra Precision SAW scale.

The balance display and UpScale must be configured to communicate with one another. Feature availability depends on compatibility and the UpScale options purchased, so the required data stream and functions should be reviewed with Arlyn before ordering.

Three Ways to Select the Right System

Choose a standard High Resolution Balance when:

  • Your samples fall within the balance’s lower capacity range.
  • Milligram or sub-milligram display increments are required.
  • The balance will operate in a stable indoor environment.
  • RS-232 or basic printing meets the data requirement.

Choose a High Resolution Balance with UpScale integration when:

  • You need the balance’s fine low-capacity readability.
  • You also need a touchscreen operator interface.
  • Your workflow requires advanced records, custom fields, user tracking or barcode functions.
  • The balance and UpScale data connection are confirmed as compatible.

Choose Ultra Precision when:

  • The load exceeds the capacity or size of the High Resolution models.
  • You need an industrial or custom-size platform.
  • You want broader connectivity and automation built into the scale configuration.
  • You require setpoints, relays, batching, filling or industrial protocols.
  • The scale must support a rugged or expandable production workflow.

Applications for High Resolution Balances

High Resolution Balances can be useful wherever small materials or samples must be evaluated with fine displayed increments. Examples include:

  • Water and environmental testing: Measuring small samples, residues or treatment materials under controlled conditions.
  • Laboratory formulation: Weighing lightweight ingredients during research and development.
  • Pharmaceutical research: Supporting laboratory procedures that fall within the model’s capacity and performance specifications.
  • Quality control: Comparing small products, components or material samples.
  • Education: Conducting chemistry, physics and material-science measurements in university laboratories.
  • Small-component inspection: Detecting small weight differences between lightweight parts.

UpScale integration may be particularly helpful when these applications also require operator identification, product information, digital records, checkweighing or networked data. Suitability for a regulated procedure must still be determined from the complete method, required tolerances, calibration program and applicable standards.

Frequently Asked Questions

What is a high resolution balance?

A high resolution balance is a lower-capacity weighing instrument that displays very small weight increments. Arlyn models offer milligram and sub-milligram readability for small samples and controlled weighing applications.

What is the difference between high resolution and Ultra Precision scales?

High Resolution Balances prioritize very fine readability at lower capacities. Ultra Precision Scales support higher capacities, larger platforms and a broader selection of native connectivity, automation and customization options for industrial applications.

Can a High Resolution Balance connect to the Arlyn UpScale Touchscreen?

Yes, a compatible High Resolution Balance can be connected to Arlyn UpScale through Third-Party Scale Integration. UpScale receives the balance’s weight-data stream and can process it through compatible display, logging and workflow modules. Compatibility and required options should be confirmed with Arlyn.

Does UpScale improve the accuracy or readability of the balance?

No. UpScale integration expands the interface, data and workflow functions. The original balance continues to determine the maximum capacity, readability, accuracy and measurement stability.

Is a high resolution balance more accurate than an Ultra Precision scale?

Not necessarily. A High Resolution Balance may display smaller increments than a particular Ultra Precision model, but readability and accuracy are different specifications. Compare the exact models, required capacity, operating environment and process tolerance.

Can these balances connect through USB or Wi-Fi?

The balance itself includes RS-232 and has a limited set of native interface options. A compatible balance connected to UpScale may gain access to USB, Ethernet, Wi-Fi and other selected functions when the corresponding UpScale options are included.

Do high resolution balances need a draft shield?

Very sensitive measurements can be influenced by air movement. Depending on the model, sample and environment, a draft shield may help improve stability. It reduces air-current effects but is not a substitute for hazardous-material containment or operator protection.

Which configuration should I choose?

Choose the standard High Resolution Balance for fine low-capacity weighing with basic RS-232 output. Add UpScale integration when you need the same balance performance with expanded touchscreen and data functions. Choose Ultra Precision when the application requires higher capacity, industrial platforms or broader native customization and automation.

Find the Right Balance and Interface for Your Application

Choose a High Resolution Balance when small samples and very fine readability are the main priorities. Add Arlyn UpScale Third-Party Integration when the balance is suitable but the application also requires a touchscreen and advanced data workflow. If your application requires higher capacity, a larger or custom platform, or more extensive industrial automation, compare the Arlyn Ultra Precision product line.
