【Manometer Gas Pressure Tester with Data Zero Function】The "return to zero" function of the manometer gauge data is easy to operate so that your readings are accurate. If you are hand holding the device, it tends to drift from zero readings, so it is best to place the manometer on a stable surface, zero it out, leave it there to take the accurate reading.
【Digital Manometer with Data Recording & Holding Function】Gas manometer data storage: 100 groups; the user-friendly design of the manometer gas pressure tester recording test data function is convenient for users to view after testing; automatic shutdown: no operation after about 15 minutes; low battery reminder: ≤6.8V 【Note】Battery: 1* 6F22, 9V, 250mAh (not included in the package)
【Differential Pressure Gauge with 12 Selectable Units】The length of the two hoses in the gas pressure gauge set is 25cm; The thread size of the barb metal connector is 1/8 inch; 12 optional units (mmHg, inHg, ftH₂O, cmH₂O, inH₂O, Pa, KPa, mbar, bar, psi, Kgcm² and ozin²)
【Multifunctional Pressure Gauge with Accurate Readings】The digital pressure gauge adopts a high-quality pressure sensor, which has the characteristics of high precision and wide range. High-precision ADC and low-power MCU. Maximum/minimum mode and DIF mode. Professional air pressure gauges are specially used for gas measurement and calibration, gas pressure system troubleshooting, laboratory testing, maintenance and installation of blowers, clean rooms, boilers and other gas appliances.
【Easy-to-Operate Exhaust Back Pressure Gauge】The exhaust pressure tester is tested at idle and 2500rpm. The pressure should be lower than 1.25psi at idle, and lower than 3psi at 2500rpms. The tester has a 2.5-inch gauge, 2 pressure units (PSI and bar), and 3 colors to indicate good or bad status. The highly visible mark greatly helps users to directly read the data.
