Televac 2A Mini Thermocouple Passive Vacuum Gauge
Starting at: $180.00
Televac 2A Mini Thermocouple Passive Vacuum Gauge
The Televac 2A VacuMini is a commercial version of Televac’s highly successful NASA 2A gauge. Our 2A VacuMini 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 VacuMini is roughly half the size and volume of traditional thermocouple vacuum gauge tubes. This thermocouple vacuum gauge’s primary limitation is that with all of our vacuum controllers, this thermocouple vacuum transducer 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 gauge also has slightly reduced accuracy over some parts of its operating range when compared to the 4A convection Pirani vacuum gauge. The VacuMini vacuum pressure gauge can be operated by several Televac controllers, including the MX200, MM200, MC300, B2A, Compact 2A, Vacuguard, and MV2A.
Has standard 1/8″ NPT Fitting for connecting to your system.

Televac 2A Mini Passive Thermocouple Vacuum Gauge
The Televac 2A Mini Thermocouple Gauge is a compact, passive Pirani-style vacuum sensor designed for rough-vacuum measurement from approximately 1×10⁻³ Torr to 1 Torr. Its stripped-down, miniaturized form factor makes it an ideal solution where space is limited—integrating easily into OEM equipment, tight process ports, or retrofit projects requiring reliable vacuum feedback with minimal footprint.
Top Benefits of the Mini 2A
- Ultra-compact design: Smaller than standard 2A, perfect for constrained spaces or inline mounting.
- Cost-effective rough vacuum sensing: Passive thermocouple (Pirani) technology offers dependable readings with minimal investment.
- Durable and simple: No electronics in the probe—robust performance with low maintenance requirements.
- Flexible system integration: Pair with compatible controllers like the MV2A or MX200 for readout, logging, or automation.
Applications Suited for the Mini 2A
- OEM instruments and vacuum assemblies where panel space is at a premium.
- Small vacuum ovens or chambers in research or industrial setups.
- Retrofits and upgrades in existing systems needing compact and reliable vacuum feedback.
- Process control segments in packaging, freeze-drying, or vent-controlled systems.
Technical Highlights
- Range: Roughly ~1×10⁻³ Torr to ~1 Torr.
- Gauge Type: Passive thermocouple (Pirani) sensor—no built-in electronics.
- Mounting: Miniature flange or threaded connection—check product variant for exact fitting.
- Calibration: Standard for air/N₂; apply correction factors when measuring other gases.
- Compatibility: Requires an external controller, such as the MV2A or MX200, to interpret signal and provide outputs.
Passive vs. Active Thermocouple Gauges
- Minimal size and cost: No built-in electronics reduce both space and price compared to active models like MX2A.
- External flexibility: You choose controller and output format—enables customized setups.
- Simplicity and reliability: Less to go wrong at the probe end ensures fewer maintenance interventions.
Integration Tips
- Match with controllers: Connect to MV2A for basic analog readout or MX200 for multi-channel, digital, or networked setups.
- Combine for full-range sensing: Consider coupling with wider-range or high-vac sensors like MX4A or MX7B.
- Install carefully: Use a clean, vertical mounting port to ensure accuracy and reduce contamination risks.
FAQs
What is its pressure range?
Approximately from 1×10⁻³ Torr to 1 Torr, tailored for rough vacuum detection.
Does the mini gauge include electronics?
No—the Mini 2A is purely passive. You’ll need a controller like the MV2A or MX200 to get readings.
Can it be used with various gases?
Yes—but keep in mind it’s calibrated for air/N₂. Use appropriate correction factors when working with other gases.
