Model 245 Pressure Transmitter DigiComp
Viatran's Model 245 DigiComp pressure sensor is among our most accurate pressure transmitters for industrial test and research applications. The 245 measures gage and absolute pressure from 3 PSI to 5,000 PSI (0.2 to 345 bar) with standard accuracy of ≤±0.06% FSO.
