Convection Gauge Tube (1 mTorr - 1.000 Torr)Rugged sensor housing of stainless steel withstanding 150 psi overpressureLess than 500 milliseconds response time for a pressure change from 10-5Torr to atmosphereCalibration medium of dry air or nitrogenOptional display (1-1,000 microns)Adjustable set point with LED indicatorThe convection gauge measures absolute pressures by determining the heat loss from a fine wire filament maintained at a constant temperature. The response of the sensor depends o
