Description
The Ultra Precision Scale is the flagship product of Arlyn Scales. But now, it comes in Intrinsically Safe version as well. The new Explosion Proof ArlynGuard S comes equipped with an Intrinsically Safe Ultra Precision SAW Load Cell sensor that provides 10x the accuracy of regular scales. Its extremely low power consumption provides long battery life from three (3) rechargeable AA batteries. It also supports external power supply through an intrinsically safe safety barrier. If your needs require a scale that needs to have a readable resolution of 1:100,000, to operate in explosive, flammable and hazardous conditions, then the ArlynGuard S would be a perfect scale for that application.
It also offers excellent temperature stability and durability. In many situations, one higher capacity SAW scale can substitute for 2 or 3 standard scales of different capacities. SAW scale technology was invented and developed by Arlyn. As with all of our scales, we only sell our scales factory direct. Other features include easy installation, easy to read graphics LCD display, full numeric keypad, and easy to use menu-driven interface. The indicator also offers Units Conversion, Net/Gross, Tare, Zero, and many other secondary functions. The optional communications interface allows communication to non-hazardous areas, giving RS-232, USB, Ethernet TCP/IP, analog 4-20mA, and setpoint outputs.
