Every Thermionics thermocouple vacuum gauge tube is individually calibrated. Each tube is matched to perform as each and every other tube of the same model so tubes can be replaced without the need to recalibrate the gauge controller. Tubes from some manufacturers are not matched -- every tube from Thermionics is maTChed™.

Thermocouple vacuum gauges offer an economical method of vacuum pressure measurement with accuracy suitable for many monitoring and control applications as well as general laboratory use. Simplicity of operation, low cost and the inherent ruggedness of these gauges has led to their widespread general use for "time proven" dependability and zero maintenance.
Thermionics offers a wide range of thermocouple gauges to suit demanding scientific, industrial and process control applications. Three basic units offer a choice in cost, materials, and power supply requirements. Additional models are variable to satisfy specialized ranges and operating conditions as well as provide interchangeability with other manufacturers' products.
All materials used in the tubes are vacuum compatible and satisfy moderate temperature and environmental requirements. Optional materials of construction are available to provide higher temperature excursions and greater resistance to environmental conditions.
We offer technical information and welcome consultation on the application of these gauges. Quantity discounts and private label packaging are available to OEM customers.

| Model No. | Description/Application | Price |
|---|
| TG-500M | Direct replacement for the Varian 531. Noble metal alloy thermocouple, excellent sensitivity and reproducibility. "Workhorse" for general use and easily calibrated for different gases. | $44. |
| TG-6343M | Fast response, long-term stability, low filament contamination under normal use. Very low supply current requirements allow use with battery-powered gauge controller (see model TGC-100B) | $42. |
| TG-6343/004M | Same as TG-6343 except manufactured with tighter tolerances to achieve a high degree of repeatability from tube to tube | $48. |
| TG-7822M | Very stable response, MilSpec vibration resistance, low filament contamination rate | $48. |
