• ✉Practical Function✉ This digital manometer has data recording and holding function, data zeroing function. Gas pressure gauge data storage: 100 groups; the humanized design of the manometer gas pressure tester recording test data function is convenient for users to view after testing. The "zero" function of the pressure gauge data is easy to operate, so the reading is accurate. If you hold the device by hand, it will deviate from the zero reading, so it is best to place the gauge on a stable surface, zero it, and place it there to get an accurate reading.
• ✉High Efficiency✉ This manometer gas pressure tester is professionally designed with wide range, high resolution and high measurement accuracy for high standard testing. It has a high-quality pressure sensor, a high-precision ADC and a low-power MCU for accurate measurement results.
• ✉Dual Ports✉ There are two ports on the top of the differential pressure gauge, one for testing positive pressure and the other for detecting negative pressure. You can choose any port to test the pressure difference between two zones (P1-P2).
• ✉12 Selectable Units✉ This digital differential pressure gauge offers 12 selectable units, mmHg, inHg, ftH2, cmHg, inH2, Pa, KPa, mbar, bar, psi, Kgcm2 and Ozin2. Meet your needs in different situations, one equipment for multiple purposes.
• ✉Large LCD Screen✉ The size of the display is 4.45CM×4.95CM, the data is clear at a glance, and the displayed data is clearer and easier to read. And it supports LCD backlight, so you can see the data clearly even at night, and the operation is more convenient
