Manometer,Professional Air Pressure Meter Dual-Port Manometer Gas Pressure Tester,12 Selectable Units Differential Pressure Gauge HVAC Gas Pressure Meter(Included Battery)

?Intelligent Dual Input?The dual input probe of the manometer can easily measure the differential pressure, the dual port manometer gas pressure tester is professionally designed with wide range, high resolution and high measurement accuracy, suitable for high standard testing, with high quality pressure sensor ?ABS material?Handheld HVAC manometer is made of ABS material, excellent high temperature resistance and impact resistance make the barometer has a long service life.4.45CM×4.95CM display, support LCD backlight, easy lighting operation, display data more clear and easier to read ?Data recording and holding function? 100 groups of gas manometer data storage; Humanized design of the manometer gas pressure tester record test data function, convenient for users to view after the test; Automatic shutdown: no operation after about 15 minutes; Low battery reminder ?12 optional units?12 optional units (mmHg, inHg, ftH?O, cmH?O, inH?O, Pa, KPa, mbar, bar, psi, Kgcm² and ozin²), two hoses in the gas pressure gauge set are 25cm long; the thread size of the barbed metal connector is 1/8 inch. ?Data zeroing function of the manometer?The "zeroing" function of the manometer gauge data is easy to operate and makes your readings accurate. If you hold the device by hand, it tends to drift from a zero reading, so it's best to put the manometer on a stable surface, zero it, and leave it there for accurate readings.
