ELECTRONIC VACUOMETER
The electronic vacuum gauge is used to accurately measure negative pressures, reaching practically the absolute vacuum, that is between 759 mm and 760 mm / Hg. This type of vacuum gauge is used by the refrigeration and air conditioning mechanic because it has a reading accuracy for pressure below 0.5mm Hg or 500mm Hg and easy to transport, today there is an electronic vacuum gauge in the format and size of the conventional manovacuometer, by lighting a leds that lights where it has graduation indicating the vacuum reached.
