Digital Differential Pressure Gauge High Accuracy Air Gas Pressure Tester Manometer

Feature: 1. LCD DISPLAY: The digital differential pressure gauge come with a backlit LCD screen, which is very convenient when working at night or in any dark place 2. POSITIVE AND NEGATIVE PRESSURE MEASUREMENT: There are two ports on the top of the manometer, one for testing positive pressure and the other for testing negative pressure. You can select any port to test the pressure difference between the two zones(P1‑P2) 3. EFFICIENT AND FAST: Using the single tube connection of the air pressure gauge, you can quickly measure the current pressure value(relative to the current atmospheric pressure) 4. DATA RECORDING, KEEPING AND ZEROING: Differential pressure gauge data storage support 100 groups; Digital pressure gauge record test data function design is humanized, convenient for users to view after the test; The zeroing function of the gas manometer data is easy to operate, so the reading is accurate 5.
