Gas Cylinder Weighing Scale (Model CWS 321)
Manufacturer: Setra
 
The Model CWS 321 Weighing Scale is designed to weigh gas cylinders to within 0.10% accuracy, reducing gas replacement costs and shutdown time. Its compressed pivot design results in a low profile (less than 1 inch) scale, ideal for easy gas bottle replacement. The multiple strain gauge design eliminates off-center-loading errors. High resistance strain gauges, combined with an additional RFI shield, produce lower susceptibility to output noise and RFI error.
