Details
Engineered for Hazardous Environments
The ArlynGuard T is certified for Class I, II, III Division 1, Groups A through G, and Class I, Zone 0 locations—ideal for chlorine ton cylinder weighing in environments with flammable gases, vapors, or combustible dusts. All components are FM Approved for intrinsically safe operation.Purpose-Built for Chlorine Ton Cylinders
Unlike generic platform scales, the ArlynGuard T features a stainless steel cradle specifically designed to hold chlorine ton containers securely in place. The low-profile frame ensures safe loading while minimizing shift or imbalance.Stainless Steel for Superior Durability
While most competing systems use painted or coated steel, the ArlynGuard T is built entirely from stainless steel. This ensures long-term corrosion resistance—critical in chlorine and other aggressive chemical environments.No Pivots or Levers—Only Accuracy
Traditional ton scales use a single load cell with a pivot and lever system that wears down over time. The ArlynGuard T eliminates those failure points with four heat-treated, stainless steel load cells that provide direct, consistent readings—up to ±0.1% accuracy.Flexible Power Options
Choose between:- Battery Operation (up to 96 hours per charge, safe-area recharge)
- AC Powered System (Configuration #2) with Zener Barrier for continuous use
Modern Outputs for Industrial Integration
Safe Area configurations support a wide range of outputs including USB, Ethernet, Modbus, Wi-Fi, and integration with Google Sheets or Arlyn’s AxChange cloud platform—ideal for SCADA, MES, or standalone logging.Available Upgrades

What hazardous environments is the ArlynGuard T certified for?
The scale is certified for Class I, II, III Division 1, Groups A–G, as well as Class I, Zone 0 hazardous locations. It meets FM Approval standards and is safe for use around chlorine gas, flammable vapors, combustible dusts, and other hazardous materials.
What makes the ArlynGuard T different from other ton scales?
Unlike generic platforms, the ArlynGuard T is specifically designed for chlorine ton cylinders. It features a stainless steel cradle, four load cells (not just one), and no pivot or lever mechanisms—resulting in greater durability, accuracy, and stability.
Why is stainless steel construction important?
Many competitive models use painted or powder-coated steel, which can corrode when scratched. The ArlynGuard T is built entirely from stainless steel, making it highly resistant to corrosion—ideal for chlorine or other chemically aggressive environments.
How accurate is this scale compared to other options?
The ArlynGuard T provides ±0.1% accuracy—up to five times more precise than pivot-based models using single load cells. The four-load-cell design ensures consistent readings, even if the cylinder isn’t perfectly centered.
Is this scale battery powered or AC powered?
Both options are available. Standard models run on rechargeable batteries (up to 96 hours per charge). For permanent setups, an AC Powered System (Configuration #2) is available and includes an intrinsically safe Zener Barrier.
Can I integrate this with our data systems or SCADA network?
Yes. Safe Area configurations support a wide range of outputs including Modbus, Ethernet, Wi-Fi, 4–20mA analog, USB logging, and even direct Google Sheets integration via our AxChange platform.
What display options are available?
You can choose from our standard MKE-5 digital indicator, the advanced UpScale touchscreen interface, or a no-display option for output-only environments. Secondary Safe Area Displays are also available.
Can I connect multiple cradles to a single display?
Yes. Dual configurations (T50-D) allow two cradles to be connected to one interface. This is ideal for facilities weighing multiple chlorine cylinders at once or managing simultaneous processes.
Is the ArlynGuard T customizable?
Absolutely. We manufacture all of our scales in-house, which allows us to offer custom cradle sizes, platform dimensions, and output configurations. Contact us to discuss your specific application.
