Digital Micron Gauge for HVAC Systems
The JB Industries DV-22N is a digital vacuum gauge built for HVAC technicians who need to measure system evacuation levels. It provides a clear LCD readout of vacuum depth so users can confirm that moisture and non-condensables have been removed before charging refrigerant.
Check Power and Connection Compatibility
Verify that your vacuum pump or manifold includes a 1/4 in female connection to match the gauge fitting. The unit runs on standard AA batteries, so ensure fresh cells are available for the job site. Operating ambient temperature must stay between 32 and 120 degrees Fahrenheit for accurate sensor performance.
Thermals Noise and Power Draw
The gauge has no moving parts, so it operates silently and generates no measurable heat during use. Power consumption is limited to the AA battery supply, drawing minimal current while the LCD is active. The included pack of ten sensor filters helps maintain consistent readings by protecting the sensor from contamination.

Questions about this item
What comes in the box with the DV-22N and what must be purchased separately?
The gauge includes ten sensor filters. AA batteries for the power supply are not included and must be bought separately.
Which measuring range version of the DV-22N should I choose?
This model has a single fixed range of 10 to 100,000 microns; no alternative capacities or versions are offered.
How does the 10 to 100,000 micron range perform on a real HVAC system?
It reads from deep evacuation at 10 microns up to atmospheric pressure at 100,000 microns, covering the full working span for standard vacuum procedures.
