MAIN FUNCTIONS OF ELITECH VGW-760:
    1.     MEASURES VACUUM LEVEL IN THE SYSTEM
* Measures pressure in the air conditioning unit after the vacuuming process, in “microns” (more accurate than psi/bar).
* 0 micron = perfect vacuum, but technicians usually target below 500 microns for a clean and dry system.
    2.     WIRELESS & PHONE CONNECTIVITY
* Uses Bluetooth, can connect to the Elitech app (iOS & Android).
* You can view micron readings live on your phone while doing other tasks.
* Also allows recording, logging & exporting data – very useful for reporting or job audits.
    3.     LEAK / MOISTURE DETECTION
* If after vacuuming, the micron reading slowly rises again → the system may have a leak or moisture.
* Helps confirm whether the vacuum truly “holds” or not.
    4.     LONG BATTERY LIFE & AUTO-OFF
* Uses 2x AAA batteries, long-lasting with auto shutdown function when not in use.
    5.     BUILT-IN AMBIENT TEMPERATURE SENSOR (°C/°F)
* Built-in temperature sensor — sometimes important when vacuuming at low temperatures (which can affect readings).
