Compatible With: MX200, MX200 EthernetIP, MX4A

Features and Benefits:

  • Low cost Pirani vacuum pressure gauge
  • Compact, robust, contamination resistant vacuum transducer
  • Numerous fittings available (1/8″ NPT, NW25, NW40, CF40, among many others)
  • Drop-in vacuum pressure gauge replacement
  • Excellent customer support for vacuum transducers
  • Filters available for highly contaminated environments

The Televac® 4A convection gauge (also often called a Pirani or vacuum pressure gauge) is a fast, robust, contamination resistant, and high accuracy low vacuum pressure gauge due to the Pirani filament design. Note that by comparison to the 2A thermocouple vacuum gauge, the 4A Pirani vacuum gauge must be mounted vertically.

The 4A convection gauge will read from 1*10-3 Torr (1 micron) to 1000 Torr (1,000,000 microns, slightly above atmosphere) as opposed to the more limited range of the 2A with our vacuum controllers. It also has improved accuracy over the 2A, with several of our active gauges and controllers offering ±10% accuracy over the full operating range of the vacuum gauge. The 4A vacuum pressure gauge can be operated by several Televac® controllers, including the MX200, MX200 EthernetIP, and MX4A.
