2A Thermocouple Vacuum Pressure Gauge Tube (Pirani)
Considered the most robust and contamination-resistant low vacuum gauge due to the Pirani filament design and operating temperature, our 2A Thermocouple Vacuum Gauge (often referred to as Pirani or Vacuum Pressure Gauge) is easy to install as it can be mounted in any orientation.

Description
The main limitation of the 2A Thermocouple Vacuum Pressure Gauge Tube is that with all our vacuum controllers, this thermocouple vacuum pressure gauge only displays from 1*10-3 Torr (1 micron) to 20 Torr (20,000 microns) instead of all the way to the 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 vacuum pressure gauge can be operated by several Televac controllers, including the MX200, MX200 EthernetIP, 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.
