WGM701 Wasp Cold Cathode Pirani

WGM701 Wasp™ Cold Cathode Pirani


WGM701 Wasp is InstruTech’s new full range vacuum gauge module which combines an inverted magnetron cold cathode with a pirani vacuum gauge sensor in a single device to provide pressure measurements from 7.60E-10 Torr to atmosphere. The pirani sensor is used to measure the pressure from atmosphere to 7.60E-03 Torr. The cold cathode sensor is then automatically activated and takes over the pressure measurements down to 7.60E-10 Torr.
