MPG40x ATM to Ultra-High Vacuum Gauge

 

The INFICON Inverted Magnetron Pirani Gauges, MPG400 and MPG401, measure from 5 x 10-9 mbar toatmosphere (3.8 x 10-9 Torr to atmosphere). Combining technologies into one single compact unit withone logarithmic analog out put signal significantly reduces the complexity of installation, setup an dintegration.

This Cold Cathode inverted magnetron Gauge MAG400 series is direct replacement of the  PTR 90 Transmitter series:
