What makes the 620G Series’ ultra-low 1⅜″ profile so important?
The ultra-low profile of the 620G Series is not just an ergonomic convenience — it’s a critical safety and productivity feature. Traditional cylinder scales are often taller, requiring operators to lift, tilt, or strain while positioning heavy and unstable cylinders. Our 1⅜″ platform height allows cylinders to be rolled or slid onto the scale with minimal effort, reducing:
- Operator fatigue from repetitive lifting
- Risk of strain injuries during loading and unloading
- Cylinder instability during placement
Is the standard construction suitable for corrosive environments like chlorine or sulfuric acid?
Yes — but with an important distinction. Every 620G Cylinder Scale includes stainless steel load cells for long-term accuracy and a stainless steel weighing pan. However, in facilities with continuous exposure to chlorine, acids, or other highly aggressive chemicals, we strongly recommend upgrading to the
All-Stainless Construction package. This upgrade replaces the aluminum frame and supports with 304 stainless steel, offering:
- Complete corrosion immunity
- Longer service life in washdown or chemical-heavy areas
- Performance parity with specialized “corrosion-resistant” competitor models — but at a factory-direct price point
How accurate are the 620G Cylinder Scales compared to other options?
The 620G Series delivers an accuracy of ±0.1% of full scale at 20 °C. Across the full operating range (14 °F to 104 °F), you can expect a maximum tolerance of ±0.25%. For perspective:
- Competing models from Force Flow offer ±0.25% or worse
- Scaletron matches ±0.1% but lacks the 620G’s cloud, data, and integration capabilities
- Premium lab-focused models like MATHESON’s DS-R offer comparable accuracy at 5× the cost
If your application requires even greater precision, Arlyn also offers its Ultra Precision SAW Series, achieving up to 10× higher accuracy.
Can I integrate the scale with my PLC, SCADA, or ERP system?
Absolutely. The 620G Series is designed to seamlessly integrate into modern control environments:
- Standard analog outputs: 4–20 mA, 0–5 V, or 1–5 V
- Digital connectivity: RS-232, RS-422, RS-485, USB, and Ethernet TCP/IP
- Wireless integration: Wi-Fi support with the UpScale touchscreen indicator
- Industrial protocols (UpScale required): Modbus RTU/ASCII, Modbus TCP, EtherNet/IP, and PROFINET
What is AxChange, and how does it improve cylinder monitoring?
AxChange is Arlyn’s proprietary cloud-based monitoring and analytics platform. It transforms your scale into an active IIoT data node, allowing you to:
- Monitor live weights from any web-enabled device
- Automate inventory tracking and eliminate manual logging
- Receive instant email or SMS alerts for low-level thresholds or unexpected usage patterns
- Generate audit-ready historical reports for compliance and safety documentation
Do I need an indicator, or can the scale run in analog-only mode?
The 620G Series is highly configurable to fit your facility’s control architecture:
- For analog-only integration, choose 2-wire or 3-wire 4–20 mA or 0–5 V outputs without a digital indicator.
- For facilities requiring on-device visibility, select the standard MKE-5 Digital Indicator.
- For advanced control, batching, or data logging, upgrade to the UpScale 7″ Touchscreen Indicator.
Are intrinsically safe versions available for classified environments?
Yes. The ArlynGuard C Series offers a Factory Mutual (FM) Approved intrinsically safe configuration of the 620G Cylinder Scale. These models are certified for Class I, II, and III, Division 1 environments, making them ideal for facilities where:
- Flammable gases are stored or processed
- Combustible dusts are present
- Hazardous classifications restrict the use of standard electronics
What warranty coverage do the 620G Cylinder Scales include?
Arlyn Scales stands behind every product we manufacture in our Long Island, NY facility. The 620G Series comes with a comprehensive warranty that covers parts and labor for manufacturing defects. In addition, our robust support model gives you:
- Direct factory access to our engineers for troubleshooting
- Rapid response times and US-based technical support
- Long-term availability of replacement components and upgrades
Can I customize the platform size, capacity, or configuration?
Absolutely. Because everything is designed and built in-house, we frequently work with facilities that require:
- Alternative platform sizes (e.g. 12″ × 12″, 14″ × 14″, or compact footprints as small as 4″ × 4″)
- Multi-scale systems managed from a single indicator
- Custom capacities for niche applications
- Load-cell kits for OEM integration into existing platforms
How does Arlyn’s factory-direct model benefit me?
By eliminating distributor and reseller markups, Arlyn can invest more into premium materials, advanced electronics, and next-generation software — while still offering competitive pricing. This means:
- More technology for less cost compared to premium competitors
- Direct support from the engineers who designed and built your scale
- Faster lead times and simplified upgrade paths
