Features with all optional accessories: Automatic Warm-up Low Battery Indicator Programmable Vacuum Level Light Replaceable Sensor (no calibration required) Sensor or Cable Disconnect Indicator (displays with Red LED) Protective Rubber Boot for Durability Heavy Duty Hook folds back into unit for compact storage AC/DC Connector capability Auto-Off after 10 minutes with disabling capabilityAs a professional technician the assurance of a deep vacuum on a system is imperative. The main problem with many small handheld units is their inaccuracy and durability. Although the thermocouple sensor has been proven to be much more accurate and durable than the thermister type, the problem has been the inconvenience of a cumbersome tabletop unit. Mastercool is introducing a hand held unit using thermocouple technology. This vacuum gauge has been designed with the technician's field environment in mind, allowing for self-calibration and a sensor that will not be damaged by small mists of oil. The Mastercool unit allows for a target vacuum range to be programmed with a light sensor indicator. Now you have the freedom to continue with your other work and come back to the system once you see the indicator light signaling your target vacuum.
