Digital Manifold Pressure Gauge Refrigeration Tester Vacuum Pressure Meter HVAC Tester Freon Pressure With Sight Glass ,Easy to Use

1.Digital refrigerant pressure gauges are made of the latest microcomputer controllers, 24-bit AD converters and high- precision pressure sensors. It not only can accurately measure the pressure of gas and liquid, but also can measure the vacuum pressure. 2.The pressure gauge has no movable parts, so it has long service life, high measuring accuracy and good long-termstability. 3 It contains the pressure and temperature parameters of common refrigerant, and the measured parameters of refrigeration system such as pressure, condensation temperature, evaporation temperature and so on are clear at a glance. 4.Widely used in refrigeration equipment, air conditioning refrigerant tools, snow seed pressure measurement, vacuum equipment, pneumatic equipment and other hydraulic, pneumatic measurement occasions.
