  • 【 High Accuracy Manometer 】 The digital manometer air and gas pressure tester adopts a high-quality pressure sensor, which has the characteristics of high precision and wide range. REC mode and DIF mode. Range: ±2.000 Psi; Accuracy: ±0.3% FS; Repeatability: ±0.25%; Linearity/Hysteresis: ±0.1% FS. Limit maximum pressure : 6Psi;
  • 【 Dual Port Pressure Measurement 】 There are two ports on the top of the gas pressure tester, one for testing positive pressure and the other for testing negative pressure. You can select any port to test the pressure difference 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).
  • 【 Data recording, Keeping, Zero function 】 Humanized design of water column manometer record test data function, convenient for users to view after testing; Before measuring, long press the "HOLD" key for more than 5 seconds to zero the differential pressure gauge, which will make the measured data more accurate.
  • 【 Large LCD Screen & Automatic Power Off 】 The air pressure meter is supported by an LCD backlight, convenient lighting operation, and display data that is clearer and easier to read. If there is no operation over 25 minutes of power-on, the manometer will automatically shut down to avoid wasting power. The handheld gas pressure manometer 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.
  • 【 11 Selectable Units & Wide Range of Applications 】 11 optional units: inH2O, Psi, bar, Mbar, kPa, inHg, mmHg, ozin2, ftH20, cmH20, kgcm2. The thread size of the barb metal connector is 1/8 inch. Equipped with simple hose connections. The air pressure gauge is suitable for ventilation and air conditioning system measurement, field calibration, and any gas pressure system troubleshooting.

SURKABA Digital Manometer features a large screen and measures pressure and differentials with multiple units. The package included multiple soft tubes, an adapter, and the manometer itself with a battery included. There is a soft carrying bag for it as well. It is convenient to use, but I am not able to evaluate if it's truly accurate. Also, it does not have some advanced features such as a magnetic back plate, but it is still a good manometer by itself.

I was only able to test this against a water manometer up to 10"H2O. It is quite sensitive to small changes in differential, so it will indicate the effect of small adjustment changes to something you are measuring. However, I did have to occasionally re-zero it while taking a series of readings. I saw drift of around 0.2-3". Not huge if you are at the top if the range, but very significant back down around a few inches. Also, it only has a zero rest, but no span adjustment. My testing indicated the accuracy does not meet the 3%FS claimed. At 2", the error was only 0.002", or .004%FS, but at 9.6" the error had already grown to .35", or 3.6%. I can't say what the error would be near full scale, but indications are it would be well above the 3% claimed.I think it performs fairly well for the price, so I gave 4 stars. But I can't give 5 stars because if you need high accuracy across the entire range (or even just the claimed 3%FS), and/or do not want to have to regularly check/reset zero, this does not do the job from what I see.

Nice portable tool.The LCD screen is easily readable with its large numbers.The tool features two ports for gas pressure. It can calculate the difference between the two ports as well for easy troubleshooting.It has an accuracy of 0.3% and has 11 measuring units.The tool also came with a few rubber tubing and one 1/8" barbed metal connector.The unit I got has a max pressure reading of 6PSI, if you need to go up to 30PSI you'd need to get their other model XF-189B which is just a few dollars more.
