Manometer Gas Pressure Tester Digital Air Pressure Meter, 12 Selectable Units Differential Pressure Gauge HVAC Gas Pressure Tester

We had a need to measure low gas pressures without spending an arm and a leg. This seems to fill the bill. Accuracy unknown as we have nothing to check it against.

EXCELLENT PRODUCT!! Does exactly what it is designed to do!! Purchased two more for my field technicians.

the digital readout is very good

Worked well for price. I used it on my furnace and then to validate the calibration on a another device. Good for light work but nit so much if you use it full time as a technician

Exactly what I needed to diagnose whether my gas line could supply enough pressure to run two water heaters at once along with everything else.Device can select from a large number of different units, as everyone seems to measure gas pressure differently. "Inches of water" seems to be preferred for natural gas systems, and it will read that directly.

The rubber tubing is not durable. It works, but I've already had to cut damaged sections off the tubing a couple times. If I use it too much, there will be none left! Also there's nowhere to store the threaded attachment in the case. It's easy to lose.As far as functionality, like I said: it works.

Good product for a good price. Exactly what I needed for my business. If you are a professional in need of super accuracy you may need to slender a lot more but this item is pretty darn good.

Not accurate for my needs, purchased another instead

Bought this after making a water column U-Tube manometer. That worked but blew the water out often. Not recommended although they are most accurate. So I bought this. Wow. It IS accurate and you can zero it. You can also set it to stop powering itself down after a few minutes, which is recommended.I used this for my RV after installing an on-demand water heater. I wanted to be sure it was getting proper pressure. I also installed a new regulator since mine was 20 years old.In my case, it's common for me to run the furnace at the same time as the water heater. So I put the furnace on and set the regulator to 11" of water based on knowing the water heater needed 11".This made a significant difference in the operation of both the furnace and the water heater. The noise from the water heater while running was greatly reduced. It's now virtually silent. And the furnace works like a top. I checked the readings with several cycles of the furnace and it's accurate and repeatable. This is a good manometer to buy. Just treat it gently as it is Chinese.Also, I was able to determine there were no leaks in the propane system after 30 minutes. Excellent. You can easily buy an adapter to fit the 3/8 flare fitting on the propane feed line to the water heater at Home Depot or most any hardware store.

Easy to use only thing it defaults measurement to kPa would have preferred default measurement in mbar

Lo utilizo profesionalmente y todo perfecto

Provato per taratura caldaia, funziona molto bene, non è uno strumento professionale ma svolge egregiamente il suo lavoro

Gut und günstig , Verarbeitung ist gut , Messwerte zeigen keine Abweichung mit Profigeräten.Habe das Messgerät für Heizthermen und Brennwertgeräte / Brenner im Einsatz , funzt im Keller sehr gut. Habe noch ein Testo für mehr € im Einsatz mit Eichprotokoll alle 12 Monate , bisher keine Abweichungen erkennbar. Schlauchanschlüsse baut sich der Fachmann bekanntlich ja selbst. ich habe hier Schläuche aus dem Ölzubehör im Einsatz 6mm hochflexibel. Die mitgelieferten Schläuche sind nicht so der Hit, kurz und eher etwas für das Labor. Insgesamt Preis Leitung Top
