HVAC Micron Vacuum Gauge, Digital Vacuum Tester with Color-Alert Display, Temp & Humidity, Anti-Burst Sensor, 11 Units, 0-75,000 Microns, 1/4" SAE Fitting, T-Connector, Batteries Included

Take the guesswork out of HVAC/R vacuum measurement with the VIVANTECH digital vacuum gauge, engineered to be a reliable micron vacuum tester for every technician. Perfect for AC, heat pump, and refrigeration evacuation, this gauge delivers a fast, accurate readout from 0 to 75,000 microns using a responsive Pirani sensor. What sets it apart is the color-changing display. As you pull a vacuum, the backlit screen visually transforms and triggers a buzzer the instant your target micron level is met, giving you an unmistakable, hands-free alert that prevents over-evacuation. To help you diagnose the system deeper, the unit also reads ambient temperature, humidity, and saturation/evaporation temperature right on the screen, so you can better judge when moisture has been fully removed. Durability matters on the job, which is why this micron gauge is built with an anti-burst sensor protection system. It resists damage from unexpected positive pressure surges, dramatically extending the instrument’s lifespan compared to unprotected gauges. The large, crystal-clear display and 11 selectable vacuum units keep readings effortless in dark crawlspaces or bright sunlight. The kit arrives field-ready with a 1/4" SAE fitting, T-connector, sturdy portable bag, and 3x AA batteries included. With VIVANTECH’s 1-year warranty, you get both a professional-grade diagnostic tool and total peace of mind.

• Professional-Grade HVAC Micron Gauge: Precisely measures vacuum from 0 to 75,000 microns in real time during system evacuation. Ideal for AC, heat pump, and refrigeration diagnostics, helping you quickly verify dehumidification and system integrity with a vacuum pump.
• Smart Color-Changing Display & Buzzer Alert: The large backlit screen visually changes color the moment your preset target vacuum is reached, while the built-in buzzer sounds off simultaneously. This dual alert prevents over-evacuation and lets you work efficiently in any lighting.
• Built-In Temp & Humidity Monitoring: Goes beyond standard vacuum readings by displaying real-time ambient humidity and saturation/evaporation temperature. These insights help you assess dehydration progress and detect potential moisture or leak issues on the spot.
• Anti-Burst Sensor Protection: Engineered with a durable anti-burst design that shields the Pirani sensor from accidental positive pressure spikes, significantly extending the gauge’s service life. Delivers fast, repeatable readings with accuracy of ±(10% rdg + 10μm).
• 11 Selectable Units & Ready-to-Use Kit: Supports microns, mTorr, Torr, mmHg, Pa, hPa, kPa, mbar, psia, inHg, and umHg. Includes a 1/4" SAE fitting, T-connector, portable tool bag, and 3x AA batteries – everything you need for field service, backed by VIVANTECH for 1-year warranty.
