Cvc penning gauge gph-320 plus extras must see
This unit powered up and the light lit when we plugged it in.
There are some minor scratches on the unit and cords, but it
seems to be in very good cosmetic shape. We are unable to
test the unit extensively, so we are selling it as untested and
The GPH-320C gauge is a single station gauge which indicates pressures on a three-range scale calibrated in units of dry air pressure. There are no short-lived components to replace. The silicon rectifier assembly is rated for twice its normal operating voltage. The high-voltage regulated transformer is checked for freedom from corona. Conservative design throughout assures long trouble-free life, and close voltage regulation makes the GPH-320C insensitive to line voltage variations.
Measures pressure from 10-3 to 1 X 10-7 Torr
Automatic voltage regulation assures stability
Sturdy stainless steel sensing tube
Available in 115VAC, 60 Hz or 230VAC, 50Hz
