2V6 Thermocouple Vacuum Gauge Tube (Pirani)

Part Number: 2-2111-0XX

Our 2V6 thermocouple vacuum gauge tube (also often called a Pirani or vacuum pressure gauge) is a direct replacement for the Teledyne-Hastings DV-6M vacuum gauge. No adjustments are needed when used with appropriate Televac, Teledyne Hastings, VRC, or Varian instruments and controllers. These thermocouple vacuum gauges are a robust solution with a measurement reading of  1*10-3 Torr to 1 Torr, and can withstand overpressure of up to 300 PSI.

The ideal vacuum controller to read from the 2V6 is the Televac VacuGuard. This low-cost digital instrument is fully self-contained and powered by a 1.5-volt battery. It will operate the 2V6, as well as our Televac VacuMini and our standard 2A thermocouple vacuum gauge.

VacuGuard Portable Vacuum Controller – The Televac VacuGuard is a small, battery-powered, portable vacuum controller that has a range of 1*10-3 Torr to 20 Torr and a bright LED display that reads in Torr and mTorr (microns). The portability of this vacuum controller makes it ideal for cryogenic and industrial gas applications where the vacuum controller needs to be carried to different (sometimes mobile) tanks to take vacuum measurements of their vacuum insulation or vacuum jacket.

2A Thermocouple Gauge – The 2A thermocouple gauge has a measurement range from 1*10-3 Torr up to 20 Torr. It
indirectly measures absolute pressure by detecting the thermal dissipation of a filament. This sensor is available in Brass and Stainless Steel with a variety of fittings to fit your system’s requirements.

MX2A Active Thermocouple Gauge – This gauge utilizes an easily replaceable Televac 2A thermocouple vacuum sensor. It has a variety of features including a wide range of measurement from 1*10-4 Torr up to 1000 Torr, RS-485 communications, two programmable set points, and a selectable analog output. The bright OLED display makes it easy to read from a distance. Options can be set from four capacitive touch controls located on the top of the unit or through RS-485 communications. The extensive selection of fittings, simplicity of use, ease of sensor replacement, and competitive cost make this unit an excellent choice for a variety of vacuum applications.
