DV-22N - DIGITAL VACUUM GAUGE

Category:
CHARGING EQUIPMENT, DIGITAL GAUGES

Sub Category:
MICRON GAUGES

JB’s DV-22 reads vacuum in seven international units: microns, PSIA, InHg, mBars, Pascals, Torr, and mTorr. The DV-22 has a micron range of 20 to 9,000 microns. It is a good idea to attach the micron gauge to the vacuum pump before evacuation to make sure the pump pulls down to at least 50 microns. If it doesn’t, your pump oil is contaminated and should be changed. A compound gauge only indicates that a vacuum is being produced, but does not tell you if moisture and acids are still present in the system. Micron gauges are the only tool to accurately read the low pressure produced when evacuation/dehydration is complete. Refer to page 11 of our catalog for more information.

DV-22N Features:

• Effective range 20-9,000 microns

• Low battery indicator alerts to replacing 9-Volt battery (not included)

• Saves last vacuum readout after shut-down

• Leak-proof with o-ring coupler to ensure proper register of vacuum

• Powers off after 10 minutes of no use to preserve battery life

• +32 degrees F to 120 degrees F (+0 degrees C to 48.9 degrees C) ambient temperature

• NIST traceable

• The female connection on this unit allows for direct connection to the A/C unit without need of hose connection

• Digital display with solid state circuitry automatically adjusts for fluctuating temperature

• T2-4 flare tee used to attach hoses to gauge (sold separately)
