First day pressure readings weren't consistent. Drastic fluctuation during readings, multiple tests on the same systems would give drastically different results, and when compared with 2 other manometer, wasn't even close to proper readings.I tried to use it day to day for over a month, I gave it a chance.It Just doesn't work. I don't recommend.

Easy to use. Used this tool to find a problem with a garage heater. Cheaper than getting a tech out to do the same thing. Good price.

apres avoir essayé une autre marque un peu moins cher, j ai du le retourné pour une variation continuelle des lectures. avec celui ci, aucune variation, et la lecture est stable. j ai reussis a bien ajusté le volet barometrique de la cheminee de notre fournaise. donc, j avais besoins de precision a des lectures tres faibles.

I've got this manometer to measure static pressures in my HVAC system. It is small, but convenient to use. It can measure positive, negative and differential pressures. I have no way to calibrate it right now, so have to trust its readings. Today I have measured 0.43 in H2O total external static pressure in my house, which is pretty good. You can also measure pressure drops over individual system components to find a restriction.I had to buy a couple of probes for the measurements. They are typical bent tubes with small holes near the tip. The diameter of the barbs on the meter is 4.9 mm, very close to the barb size on the probes. The included silicone tubes measure 3 mm ID and 5 mm OD and fit both the meter and the probes just fine. The power comes from three 1.5V AAA cells. I have used rechargeable NiMH cells and they work just fine. For the future I can measure the pressure drop across the air filter to decide when it is the time to replace it. It is a useful tool in every household.04-27-24 update. Today I was able to calibrate (kind of) my gauge against a precision calibrated Heise gauge. I was not able to go below 6 in H2O, but from 6 to 83 in H2O both gauges showed very close numbers. It was not a proper calibration, but it showed that I can trust this gauge. It even generated an overpressure error, when I slightly exceeded 83 in H2O.

Utilizzato per tarare il min/max del gas in uscita dalla valvola boiler, ha funzionato. Il tubicino in dotazione è piccolo e nel mio caso mi sono dovuto ingegnare con un piccolo giunto e spezzone di tubicino adatto alla presa sulla valvola gas. Soddisfatto dell'acquisto.
