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)

QED manufactures precision helically wound Bourdon tube pressure gauges, pressure switches and pressure gauge/switch combinations for a wide range of demanding applications.

The Bourdon tube design offers both extreme simplicity and reliability. When pressure is present at the tubes open end, it causes the tube to unwind predictability. (read more)

Vacuum Research's thermocouple vacuum gauge is a simple and low cost instrument for vacuum measurement in the popular 1 to 1000 mTorr range (microns). It operates with any line voltage from 90 to 240V at 50 or 60 Hz, and can be used with our VRL-6 or Hastings DV-6 gauge tubes. A 0 to 5 VDC analog output is standard on both the indicator and dual set point controller models. (read more)

The new DV-6S Tube has been designed for rigorous vibration and shock applications. This new gauge tube is specifically designed for outdoor use on cryogenic tanks including railcar and tanker truck applications. The gauge tube is compatible with other Hastings products, but specifically the handheld HPM-4/6. (read more)

WIKA announces its new Type 232.34DD Direct-Drive Gauge. The instrument incorporates "bourdon-tube" theory with a spiral wound bourdon tube. However, it eliminates the "movement components" found inside the typical bourdon tube pressure gauge. This results in fewer moving parts, among other advantages. (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)

A range of precision–formed pipe and tube assemblies, for the reliable transfer of high pressure gases used in Cryogenic Cooling of IR Detectors, Radar Waveguide pressurisation, Stores Ejection and Actuation systems, and Air-Oxygen systems. (read more)

Convection gauges are very popular because they can measure from atmosphere to 1 mTorr. More properly described as "Convection Enhanced Pirani Gauges," these rugged and inexpensive instruments can directly interface with your PLC to control all crossovers and inititate substrate heat down to 1 X 10-3 Torr.
