Elitech VGW-Mini Wireless Digital Vacuum Gauge with Adaptor Rechargeable Pressure Tester Meter HVAC 0-19000 Micron, Alarms via APP, Offline Recording, Temp Compensation, 1/4" SAE
- UPGRADED ELITECH TOOLS APP(ioS and Android): An intergraded app, that allows users to manage all Elitech tools such as vacuum pump, digital manifold, vacuum gauge, pressure gauge, refrigerant charging scale on one app, more efficient and more intelligent.
- MULTIFUNCTIONAL DESIGN: Settable target, notifications will be sent when readings exceed the predetermined value. The data can be recorded and exported in Excel and PDF format.
- INTELLIGENT JUDGEMENT OF H2O STATUS: The vacuum meter automatically judges physical state of H2O by comparing ambinent temperature and water saturation temperature corresponding to the vacuum in the system.
- LARGE DISPLAY: Continual digital readout of evacuation process can be viewed easily on the large, full-view LCD screen.
- WIDE MEASUREMENT RANGE & HIGH ACCURACY: Used to test system leak and discern vacuum pump quality of the evacuation in an HVAC and refrigeration system; accurate measurements from 19,000 Microns (atmosphere) to 0 Micron. Accuracy: ±10% or ±10 Micron
- NOTICE: There is an oil proof film inside the head of the product, which may cause a delayed numerical display when directly connected to the vacuum pump. We suggest to remove the oil film when connecting the vacuum pump and reinstall it when connecting the system.

NoteTroubleshooting recommendation: Use an angled adapter to connect the vacuum gauge directly to the vacuum pump, and perform a vacuum test without the oil filter membrane installed. Ensure all connections are well-sealed, then observe whether the vacuum level can drop below 40 microns within 1 minute. If it does, the vacuum gauge is functioning properly; if not, there may be a leak. To ensure accuracy, it is recommended to repeat the test and keep the testing environment free of moisture.
Oil filter membrane: This product is equipped with an oil filter membrane designed to prevent vacuum pump oil mist from entering the vacuum gauge sensor, protecting the device from oil contamination and extending its service life. The oil filter membrane effectively ensures measurement stability during long vacuum evacuation processes. Please note that the oil filter membrane may slightly affect response speed and ultimate vacuum level during short, no-load vacuum tests. If performance comparison tests are needed, it is recommended to temporarily remove the oil filter membrane.
Precautions: To ensure accurate vacuum gauge readings, keep all connections tight and sealed. Regularly check and replace the protective oil film. If readings become unstable, inspect and gently clean the sensor with a suitable cleaner. Oil on the sensor or film causes inaccurate measurements.
2700 Pa:The VGW-Mini only starts displaying readings when the vacuum is below 2700 Pa (approx. 27 mbar). If the customer's analog gauge shows 50 mbar (approx. 5000 Pa), the vacuum level hasn't reached the measurable range yet. Recommend continuing evacuation to see if the pressure drops into range.
Charging Guidelines: Use a standard 5V/1A adapter. Do not use high-voltage fast chargers (such as 9V/12V PD fast chargers), as this may cause the small lithium-polymer battery to overheat and swell.
