The Agilent 536 thermocouple gauge is ideally suited to your rough vacuum applications. The gauge measures total pressures in the 1 x 10^-3 to 760 Torr (ATM) absolute range (1.3 x 10^-3 to 1013 mbar). The tube body is made out of 304 stainless steel and has a Platinel filament. This TC gauge has a baffle to extend the sensor life in the presence of condensable gases and improves performance at higher pressures.

Meanwhile, the thermocouple gauge simulator provides a way of calibrating and adjusting the zero setting on a thermocouple gauge controller. Set it to simulate either 760 Torr (atmosphere) or 10^-4 Torr.
