Our Top 10 Best differential pressure gauges On The Market

1. CMTOOL Manometer 12 Selectable Units Differential Pressure Gauge, Dual Port Manometer Gas Pressure Tester, Digital Pressure Gauge with Backlight Professional Air Pressure Meter Handheld HVAC Manometer

Features :

  • 【Portable Manometer with ABS Material and LCD Display】The handheld digital pressure gauge is made of ABS material, and the excellent performance of high-temperature resistance and impact resistance makes the air pressure meter have a long service life. 4.45CM×4.95CM display, support LCD backlight, convenient lighting operation, display data clearer and easier to read.
  • 【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.
  • 【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)
  • 【Manometer for Measuring Positive and Negative Pressure】There are two ports on the top of the differential pressure meter, one for testing positive pressure and the other for testing negative pressure. You can select any port to test the pressure difference (P1-P2) between the two areas. Using the single pipe connector of the air pressure meter, you can quickly measure the current pressure value (relative to the current atmospheric pressure).
  • 【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)
  • 【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.
