Description
The GPH-320C circuit is designed for years of trouble-free operation. Conservative design throughout assures long trouble-free life, and close voltage regulation makes the GPH-320C insensitive to line voltage variations. The GPH-320C gauge is a single station gauge which indicates pressures on a three-range scale calibrated in units of dry air pressure. The basic gauge is available in 115VAC, 60 Hz.
Features
- Measures pressure from 25 X 10-3 to 1 X 10-7 Torr
- Cabinet or half-rack mounting
- Sturdy stainless steel sensing tube
- Recorder output
- Available in 115VAC, 60 Hz
