Description
The JB Industries DV-41 Micron Gauge is an essential diagnostic tool for HVAC technicians performing system evacuations. This digital vacuum gauge measures system vacuum in microns (millitorr), providing the precise readings needed to verify that a refrigerant system has been properly evacuated before charging. Unlike manifold gauges that cannot accurately measure deep vacuum levels, the DV-41 displays readings from 0 to 9,999 microns with high accuracy, confirming moisture removal and system integrity. The large digital display is easy to read in any lighting condition, and the 1/4" SAE flare connection fits standard vacuum pump and manifold hose fittings. Proper evacuation to below 500 microns is required by most equipment manufacturers—this gauge ensures compliance and protects system warranties.
