Dry Battery Digital Vacuum Gauge
This product, built with Pirani professional vacuum sensor, can precisely measure the vacuum
level for getting the information of best dehumidification and removal of foreign matter (such as
oil, impurities, etc.), obtaining the best status for charging refrigerants, real-time monitoring and
measuring the leakage to the vacuum system, distinguishing the vacuum pump quality.
1/ Operated by mobile phone.
2/ Long wireless range to monitor vacuum.
3/ Smart vacuum pump will shut off automatically
after reaching the pre-set vacuum on the vacuum gauge.
4/ Auto power-off.
5/ Higher accuracy sensor
6/ Larger Maximum overload pressure,500psi✔ Product Description
