상품특징
Make sure this fits by entering your model number.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 vacuumPowers 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 temperatureNIST traceable - The female connection on this unit allows for direct connection to the A/C unit without need of hose connectionAutomatically adjusts for fluctuating temperature - T2-4 flare tee used to attach hoses to gauge (sold separately)
상품설명
JB\'s DV-22 reads vacuum in seven international units: microns, PSIA, In, bars, Pascal\'s, Torre and more. 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.
