The Edwards APG100-XM Active Pirani Vacuum Gauge measures vacuum pressures in the range 10-4 mbar to 1000 mbar. It operates using the principle of thermal conductivity in which the rate of heat loss from a heated filament is dependent on pressure of gas surrounding the filament. It contains a NW16, KF16 vacuum flange, is compact for easy installation, has a linear output, and a user replaceable tube sensor. They measure pressure from 1000 down to 10-3 Torr. The APG100 can be mounted in any orientation however the gauge tubes are individually factory calibrated in nitrogen whilst vertical.
