What hazardous environments is the ArlynGuard P certified for?
The ArlynGuard P is certified for Class I, II, and III Division 1, Groups A–G, and Class I Zone 0 hazardous environments. It also meets Division 2 (nonincendive) requirements for flammable gases, dusts, and vapors. For full approval documentation, contact us or refer to the FM Approval Guide.
Can I use this scale around hydrogen, acetylene, or combustible dusts?
Yes. The scale is approved for Groups A through G, which include hydrogen (Group B), acetylene (Group A), and various dusts (Groups E–G). This broad certification ensures compatibility with most common industrial hazards.
What’s the difference between Division 1 and Division 2?
Division 1 covers areas where hazardous substances are present under normal operating conditions. Division 2 applies to areas where hazards are present only under abnormal conditions (e.g., a leak or equipment failure). The ArlynGuard P is certified for both, giving you maximum flexibility and compliance.
Is AC power available, or is it battery only?
Both options are available. The standard model includes rechargeable NiMH batteries with up to 96 hours of use. For continuous operation, an AC Powered System (Configuration #2) is available and includes an Intrinsically Safe Zener Barrier.
Can I integrate this with a PLC, SCADA system, or cloud software?
Yes. Optional Safe Area configurations support industrial protocols like Modbus, PROFINET, and EtherNet/IP, as well as modern outputs like Ethernet, Wi-Fi, USB, and direct integration with Google Sheets or AxChange Cloud Monitoring.
Is this scale suitable for chemical or corrosive environments?
Yes. The standard platform is aluminum, but stainless steel platform upgrades are available for environments involving harsh chemicals or frequent washdowns. All load cells are heat-treated stainless steel for corrosion resistance.
Can the ArlynGuard P be customized for a specific size or capacity?
Absolutely. In addition to our standard platform sizes (16" x 18" to 48" x 48"), we can build custom dimensions or adjust capacity to meet your exact application. Contact us for a custom quote.
Does it support part counting or flow rate monitoring?
Yes. Parts counting is supported across all configurations. Flow rate monitoring and alarm functions are available via the UpScale Touchscreen Display (Configuration #4) in a safe area setup.
