About this item

  • 【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.

Difficult to understand. I now have gone back to slack tubes.

The tester appears to work well as intended.However I purchased this because the first reviewer showed a case to house the tester.This was not included as I had expected. Bad assumption on my part.

My Generac 13kw standby generator was having a lot of engine "searching"problems. This was due to excessive NG pressure. I purchased this CMtool manometer, to aid in the proper setup and adjustment. It worked perfectly and the learning curve was not at all difficult. A lot less expensive than others and appears to also be quite accurate. I have no problem recommending this tool to other DIYers.

I wish it was rechargeable, I'm not a big fan of 9VDC especially if you are not going to use it for a while.Asides from that it works well on Big Maxx heatter I got a hard case for it to keep everything secure .

For the price, it worked. I used it to balance a new energy recovery ventilator (ERV). The supplied rubber tubing was too short by about 4 inches and I needed to order longer ones. As advised by other purchasers, it did work but you have to keep the tubes as straight as possible.
