Digital Vacuum Gauge

Our digital vacuum gauge series is built around the WZ-VG100 High-Precision Digital Vacuum Gauge, featuring a backlit digital display and audible alarm, with four selectable vacuum units (Pa, mbar, mmHg, microns). It offers a measurement range of 0–10,000 Pa, with an accuracy of ±5% of reading between 2–100 Pa (at 20°C), and a maximum oil overload pressure of 14 PSI/0.1 MPa — suitable for high-precision applications such as refrigeration system evacuation testing and laboratory vacuum measurement.

The accompanying Rapid-Y connectors are designed specifically for vacuum hose connection and splitting, built from high-quality materials to ensure sealing performance and durability under extreme vacuum conditions. The two versions accommodate 3/8" to 3/8" and 3/8" to 1/4" hose connections respectively, with custom thread sizes available in 1/4", 3/8", 1/2", and other specifications. The digital vacuum gauge series is widely used in refrigeration system evacuation testing, vacuum defoaming bucket connections, and laboratory vacuum line setups — a key measurement tool for ensuring accurate, reliable evacuation work.
