Ideal for applications that monitor heavy weight cylinders, containers and tanks that require very high precision alerts, these scales are also used in every application where precision and extreme durability are important. Arlyn Scales introduces patented new SAW (Surface Acoustic Wave) Technology – a breakthrough in the scale industry. It utilizes an All Digital system to provide unrivaled accuracy that is 10x better than standard scales, with a resolution that is up to 20x better. 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. Not only is this scale extraordinary in accuracy, but it was also built to last with a diecast aluminum frame, stainless steel weighing pan, and click type switches. 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.
