Vacuum Research's thermocouple vacuum gauge is a simple and low cost instrument for vacuum measurement in the popular 1 to 2000 mTorr range (microns). A 0 to 5 VDC analog output is standard on both the indicator and dual set point controller models. Operates with the gauge tubes listed below or any Varian 531 or 536 tube. (read more)

The convection gauge is the lowest cost instrument that can provide a continuous monitoring and control of your vacuum system from atmosphere all the way down to 1 mTorr. (read more)

The convection gauge is the lowest cost instrument that can provide a continuous monitoring and control of your vacuum system from atmosphere all the way down to 1 mTorr. The gauge tube is all stainless steel and has both 1/8 inch NPT and 1/2 inch O.D. smooth tubulation for sealing in compression ports. (read more)
