Features and Benefits:
- Low cost Pirani thermocouple vacuum gauge tube
- Compact, robust, contamination resistant vacuum pressure gauge
- Numerous vacuum transducer fittings available (1/8″ NPT, NW25, NW40, CF40, among many others)
- Drop-in thermocouple vacuum gauge tube replacement
- Excellent customer support for vacuum pressure gauges
- Convection gauge filters available for highly contaminated environments
Our 2A thermocouple vacuum gauge tube (also often called a Pirani or vacuum pressure gauge) is widely considered our most robust and contamination resistant low vacuum pressure gauge due to the Pirani filament design and operating temperature, and it’s simple to install because it can be mounted in any orientation. The 2A thermocouple vacuum pressure gauge tube’s primary limitation is that with all of our vacuum controllers, this thermocouple vacuum pressure gauge will only read from 1*10-3 Torr (1 micron) to 20 Torr (20,000 microns), instead of all the way up to atmosphere (760 Torr).
This vacuum pressure gauge also has slightly reduced accuracy over some parts of its operating range when compared to the 4A convection vacuum gauge. The 2A thermocouple vacuum gauge tube can be operated by several Televac® controllers, including the MX200, MX200 EthernetIP, MX200 PROFINET, MX2A, B2A Portable, Compact 2A, VacuGuard™, and MV2A. With the MX2A, the full measurement range from 1*10-3 Torr (1 micron) to 1000 Torr (1,000,000 microns) is available.
