Description
Robinair RAVG-1 Digital Micron Vacuum Gauge
The Robinair RAVG-1 is a job-ready digital micron vacuum gauge built for HVAC/R evacuation work. It gives clear vacuum readings during commissioning, service and repair so you can verify moisture removal and confirm the system is holding a deep vacuum before charging.
With a MEMS Pirani sensor, six measurement scales, a tri-colour backlit display and an operating range from atmosphere to 10 microns, this gauge suits technicians who want accurate evacuation checks without guesswork.
Key Features & Benefits
- Measures vacuum from atmosphere down to 10 microns for deep evacuation verification.
- Reads in microns, mmHg, inHg, mBar, Pa and Torr for flexible workflow preferences.
- MEMS Pirani sensor supports stable field measurement during evacuation testing.
- 5-digit LCD with tri-colour backlight helps you read status quickly on site.
- ~31 bar / 450 psi overpressure resistance adds protection in day-to-day service work.
- Compact format suits split system, refrigeration and general HVAC/R commissioning tasks.
Product Details
A micron gauge is not just a nice extra during evacuation. It is the tool that tells you whether the system has actually reached and held a deep vacuum. The RAVG-1 is designed for technicians who want a dedicated digital gauge for evacuation verification rather than relying on rough manifold readings.
Use it during installation, repair and recommissioning work to monitor pull-down progress, isolate the pump, and confirm the system stabilises at an acceptable vacuum level. For tradies working across residential air conditioning, refrigeration and light commercial jobs, this is the kind of tool that helps reduce guesswork and call-backs.

FAQs
Q: What does a digital micron vacuum gauge do?
A: It measures deep vacuum during evacuation so you can confirm moisture and non-condensables have been removed before charging the system.
Q: Why use a micron gauge instead of manifold gauges alone?
A: Manifold gauges are not accurate enough for deep vacuum measurement. A dedicated electronic vacuum gauge gives the sensitivity needed for evacuation verification.
Q: Where should the gauge be connected during evacuation?
A: For the most meaningful reading, fit the gauge on the system as far away from the vacuum pump as practical, then isolate the pump and allow the reading to stabilise.
Q: What units does the RAVG-1 display?
A: It reads in microns, mmHg, inHg, mBar, Pa and Torr.
Q: Who is this gauge best suited to?
A: It suits HVAC/R technicians, apprentices, contractors and service teams who need accurate evacuation verification on air conditioning and refrigeration jobs.
