Details
Built for the Most Hazardous Environments
The ArlynGuard F series is certified for use in the most volatile industrial settings—Class I, II, III Division 1 Groups A through G and Class I, Zone 0 environments. This includes flammable gas zones (like hydrogen and acetylene), combustible dust areas, and ignitable fibers found in oil refineries, chemical plants, and agriculture processing facilities. Factory Mutual (FM) approvals cover all key components, including the MKE-5-IS Indicator and Arlyn’s proprietary load cells.Engineered for Abuse, Built to Outlast
Every ArlynGuard F model is equipped with industrial-grade, heat-treated stainless steel load cells—not aluminum or mild steel. These cells are protected in reinforced steel frame pockets designed to withstand forklift hits, pallet drops, and shock loading. The deck is a thick diamond steel plate with a durable, three-part epoxy coating. For harsh chemical or washdown environments, full stainless steel platforms are also available.High-Capacity Performance with Reliable Accuracy
With standard capacities ranging from 2,500 to 20,000 lb and a resolution as tight as 0.5 lb, ArlynGuard F is a workhorse for bulk weighing, pallet tracking, and drum batching. Internal resolution reaches 1 part in 500,000 with 0.1% accuracy across all models—ideal for production environments where safety and throughput matter more than ultra-fine precision.Battery or AC Power—Your Choice
Standard models operate on three rechargeable NiMH AA batteries with ~96 hours of use between charges (safe-area only). For continuous operation, an AC-powered version is available (Configuration #2), using an Intrinsically Safe Zener Barrier to maintain compliance in hazardous areas while eliminating downtime.Clear Displays, Flexible Controls
Each scale includes a stainless steel swivel-mount digital display with a large graphical LCD and 1” high digits. Functions include automatic tare, stored tare memory, net/gross toggling, and unit conversions (lb, kg, oz, etc.). Need a different setup? Choose from a touchscreen interface, remote display, or even a no-display configuration for PLC-integrated systems.Smart Integration Options (Safe Area Only)
Modern industrial operations often require data output and automation. ArlynGuard F supports optional safe-area communication outputs like:- USB, RS-232, Ethernet, Wi-Fi
- Modbus RTU/TCP, PROFINET, EtherNet/IP
- Cloud monitoring via AxChange, Google Sheets integration, Data logging with no PC required
- These options are available via safe area display configurations (see Configuration Guide below).
Built in the USA, Backed by Engineers
Manufactured in Long Island, NY, every ArlynGuard F scale is designed, built, and supported by Arlyn’s in-house engineering team. That means faster service, better customization, and no distributor markups—just rugged performance and expert support direct from the source.Available Upgrades

What hazardous environments is the ArlynGuard F certified for?
The ArlynGuard F is certified for Class I, II, and III Division 1 hazardous locations, including Groups A through G, as well as Class I, Zone 0 environments. It is also rated for nonincendive use in Division 2 locations. That includes flammable gases (like hydrogen and acetylene), combustible dusts (like carbon black or flour), and ignitable fibers. Contact us if you need help verifying a specific application or material.
Can I use this scale in a washdown or corrosive environment?
Yes. The standard platform includes a chemical-resistant epoxy coating, and an optional full stainless steel construction is available for more aggressive washdown or corrosive settings. Contact us to confirm the best option for your environment.
What’s the benefit of the AC-powered option?
Our AC-powered system (Configuration #2) includes an Intrinsically Safe Zener Barrier and is ideal for continuous-use environments where battery swapping is inconvenient or not feasible. It allows the scale to be permanently powered from a safe area.
Can I integrate this scale with a PLC or SCADA system?
Yes. ArlynGuard F supports multiple industrial protocols including Modbus, PROFINET, EtherNet/IP, and analog outputs (4–20mA or 0–5VDC). Integration is available through Safe Area configurations with the appropriate display and barrier setup.
Does it support wireless or cloud-based data logging?
Yes. With the UpScale Display in a Safe Area (Configuration #4), you can enable Wi-Fi, log data directly to Google Sheets, or monitor in real time via Arlyn’s AxChange cloud platform.
How long does the battery-powered version last?
Typical operation is up to 96 hours per charge. Each unit includes rechargeable NiMH batteries and a spare set with a charger. Batteries must be changed and recharged in a designated safe area.
Can I get a custom platform size or capacity?
Yes. Since all ArlynGuard F scales are manufactured in-house, we offer a wide range of custom platform sizes and weight capacities. Let us know your exact requirements and we’ll design a system to match.
Can I operate the scale without a display?
Yes. Configuration #5 allows for a no-display option with an analog output. This setup is ideal for customers who need to route weight data directly to another system without using a local display.
How accurate is the ArlynGuard F?
All models offer ±0.1% of full-scale accuracy with internal resolution up to 1 part in 500,000. For example, a 5,000 lb capacity scale delivers 5 lb accuracy—ideal for bulk, pallet, and drum applications. For ultra-precise needs, consider the ArlynGuard S series.
