Tested, works great. Pumped down and was sensitive in the lowest regions of its range. Full Scale range is 10 Torr, so it's precision is down to 10 mTorr. Used formerly, has some scratches and dents from use. See photos for the test we ran. Relay points work fine.
Has a KF16 quick connect vacuum fitting. Pinout diagram is shown on the side of the gauge.
From the manufacturer:
The 625H Absolute Capacitance Manometer features two user adjustable process trip point relays, each with an adjustment range from 0.1% to 100% of Full Scale or voltage equivalent 0.01 to 10 VDC. Dual color LEDs indicate relay status. It is temperature controlled at 100°C.
-Temperature controlled to 100°C for 0.25% of reading accuracy
-0 to 10 VDC analog output proportional to absolute pressure
-Two adjustable process trip point relays
-Measures total pressure directly, independent of gas composition
