What environments is the ArlynGuard C certified for?
The ArlynGuard C is certified for use in Class I, II, and III Division 1 hazardous environments, including Groups A through G. It also meets standards for Class I, Zone 0 areas with flammable gases and vapors, as well as dusty or explosive atmospheres like those found in labs, refineries, and chemical plants.
Can I use this scale to monitor gas cylinder usage?
Yes. The ArlynGuard C is purpose-built for weighing compressed gas cylinders with precision and safety. It supports capacities from 60 to 400 lbs and offers high-resolution readings ideal for monitoring cylinder contents.
What’s the benefit of upgrading to AC power?
The new AC power configuration (Configuration #2) supports continuous use without the need to recharge batteries—ideal for operations that require constant monitoring or high throughput. It also simplifies integration with permanent control systems.
Do I need a display in the hazardous area?
Not necessarily. You can configure the scale with a Safe Area Display or even choose a No Display option if you’re routing data directly to a PLC, SCADA system, or software interface. Contact us to match your setup with the right configuration.
How do I export weight data or integrate with other systems?
Safe Area configurations support outputs like USB, Modbus, Ethernet, and even Wi-Fi. We offer Google Sheets integration, USB data logging (no PC required), and SCADA-ready protocols via our optional UpScale Indicator.
Is this scale suitable for corrosive or wet environments?
The standard platform is made from rugged stainless steel and aluminum. For highly corrosive or wet areas, we offer an upgrade to a full NEMA-rated stainless steel enclosure. Contact us with details about your environment to confirm compatibility.
Can the scale count parts or track flow rate?
Yes. Parts counting is included by default. If you're dosing gases or tracking depletion rates, the optional UpScale Indicator adds a Flow Rate Function with alarms, ideal for process control and alerts.
