Digital Pirani Vacuum Gauge DPRG-2GH-SP

Digital Pirani Vacuum Gauge DPRG-2GH-SP

IHVP Measuring Equipment

The 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 gases. The Model DPRG-2GH-SP unit covers the range from 0.001 mbar to 20 mbar, and controls relay with independent set point. It is a dual channel gauge, channel selection from front bezel membrane switch.
