About this item

  • 【Multifunctional Pressure Gauge】Digital pressure gauge can measure +/-2.999psi or +/-20.68Kpa with an accuracy of +/-0.29%FSO and a resolution of 0.001, displaying ambient temperature of -40°F~176°F (-40℃~80℃) with high accuracy and wide range , max/min mode and DIF mode
  • 【12 Optional Units】 12 optional units (mmHg, inHg, ftH₂O, cmH₂O, inH₂O, Pa, KPa, mbar, bar, psi, Kgcm² and ozin²) 3 measurement modes (Max, Min. differential DIF) and the simple operation design with 5 buttons help you use this 200g portable differential pressure monitor easily
  • 【Dual Input Ports】There are two ports on the top of the differential pressure monitor, one for testing positive pressure and the other for testing negative pressure, you can choose either port to test the pressure difference between these two areas (P1-P2), equipped with two 4mm diameter hoses and a standard 1/8 inch hose adapter, the practical air pressure tester can be used to check and replace gas valves in natural gas furnaces, diagnose waterless tanks water heaters and measure static pressure in duct systems, etc
  • 【Zero Out】Support "zeroing" function, which can easily clear the remaining data and ensure to get accurate gas pressure measurement readings. Data storage 100 groups, auto shutdown: no operation after about 15 minutes Low battery alert: ≤ 6.8V [Note] Battery: 1*6F22, 9V, 250mAh
  • 【Easy to Use】Large LCD display prevents eye fatigue and clearly displays differential air pressure readings even in the dark.The professional air pressure gauge is specially designed for gas measurement and calibration, gas pressure system troubleshooting, laboratory testing, maintenance and installation of blowers, clean rooms, boilers and other gas equipment

Simple enough for me to use.Backlight display works well when you push the button.I would buy it again.

inaccurate manometer. I use it in hvac for checking gas pressure and i get wild readings that are incorrect. Compared to a stable fluke tester this is not useable.

I like that this is a small hand held unit that is simple to use. I use this unit to adjust my homes a/c vent balance. The small handheld held unit was easy to carry into the attic space, and comes with the tubing necessary for operation. Great for household use and accurate for my project.

This manometer comes in a soft zippered case. Lightweight case and the zipper operates smoothly. I got this to read both 2 psi and 7 in H20 natural gas . Both before and after a natural gas regulator. It worked fine for my needs. The numbers are easy to use and read. The buttons are gray with bold white lettering. The power button is red and easy to recognize over the other. The buttons have a good solid feel to them when pushed, not spongy.I am glad that I had this manometer to use on the project that I am doing. Served my needs fine and will have it for any future piping that I need to do . This is a good inexpensive meter.

I was able to successfully diagnose the faulty pressure switch of my furnace. It was difficult to diagnose since there are several aspects of the furnace that could lead to the pressure fault. I installed the manometer and let the furnace run and waited for the fault to manifest itself. The manometer proofed the pressure switch was periodically malfunctioning (sticking and wouldn't close) which led to the fault condition.

Ein tolles Gerät! Im Gegensatz zu billigeren hat es einen deutlich größeren maximalen Messbereich und kann daher gut für mehr als nur die Belüftung von Innenräumen eingesetzt werden. Es war auch viel Zubehör für diverse Anschlüsse dabei, was sehr praktisch war. Ich habe keine Möglichkeit die Genauigkeit zu testen, die Werte sind aber zumindest plausibel. Würde es jederzeit wieder kaufen!

This is a very well constructed product. It does exactly what the manufacturer claim. The monometer can detect several different physical variables. I only needed to test one physical variable.

1/4” barb only. Too small for typical ports.
