Digital pirani vacuum gauge

The UVS Model DPRG series Vacuum Pirani Gauge Controller displays vacuum pressure as measured from a S-PR-GH sensor tube. It displays vacuum measurements based on thermal conductivity of air or nitrogen. The Model DPRG-XGH-SP controller covers the range from 0.001bar to 1000 mbar, and controls relay with independent set point.
***The optional RS232 along with analog output 0 to 10V and 4 to 20 mA facility can be obtained on request
