VKALTULmanometer gas pressure tester is designed with imported pressure sensors, high precision ADC and low power consumption MCU. It features professional digital pressure gauge with high precision, wide range, high resolution, large screen display and indoor temperature measurement.
This manometer HVAC can be extensively used in natural gas pipelines, air condition and refrigeration ventilation systems, mechanical hydraulics, plastic moldingceramic products manufacturing, biopharmaceutical molding, mining pressure testing, etc.
The manometer hvac with 4.45cm × 4.95cm high-definition display screen, which is clear and easy to read, also supports LCD backlight display, and can easily read data even in dark environments. 12 optional units (mmHg, inHg, ftH₂O, cmH₂O, inH₂O, Pa, KPa, mbar, bar, psi, Kgcm² and ozin²).
With a single channel it is possible to quickly measure the current detection pressure value(relative to the current atmospheric pressure), whereas the dual channel allows simultaneous detection of the pressure difference between the two detection ports(p1-p2).
The digital gas manometer has the storage function, which can store 100 groups of data. No operation for 15 minutes will automatically shut down. In addition, this manometer gas pressure tester also has a low battery reminder function, which can give a timely warning when the battery is low.

My furnace output was very low after replacing the gas valve, it turned out the factory-supplied gas valve was set to 1wc, and my furnace needed more than 3x higher pressure, I would have never been comfortable blindly increasing it that high, but with the manometer it was mostly easy as long as you know what you are doing and you correctly zero out and change the units on the device, burners still had blue flame after adjustment and the furnace runs super hot again.Safety-wise, I would not recommend everyone does this unless you have some confidence and are usually a DYI-er with some experience working with gas and watch a ton of how-to videos.Four stars for sending me an obviously used product, with minor scratches on the unit, and an open box, Amazon should have at least offered a discount for this item but chose to send it as new...Shame.The battery is NOT included, uses the regular square 9v.

I have a home generator and the gas pressure changes over time. I have to change the pressure at the regulator and I can obtain the correct pressure using this instrument.

I like the size and functionality of the unit. I don't like that you can't calibrate the unit. otherwise good quick tool for reading pressures of all types.

I picked up this manometer after learning that my car's engine is notorious for vacuum problems because the PCV orifice inside the intake manifold gets clogged. Sure enough, I had positive pressure in my crankcase at idle as blow-by gasses were building up and fouling the oil among other problems. Once I got the the PCV cleaned out, the manometer confirmed that I have vacuum again. I also checked the accuracy by measuring the pressure on my CPAP and it read 17cm/H2O exactly as it should, so this thing seems to be spot on.

Die deutsche Anleitung fehlt. Ich habe nur durch probieren herausgefunden, wie man den Nullpunkt setzt und es kontinuierliche Differenzdruk Messwerte anzeigt. Ich war am überlegen es zurück zu senden, aber da es mir für den Preis meine gewünschten PA Werte anzeigt, habe ich es behalten. Es ist etwas kompliziert, da wohl alle Tasten dreifach belegt sind. Je nach dem, wie lange man sie drückt.

This is a brilliant little tool. I’d never used one before and this was simple and easy to use. It’s very basic but seems to work really well. Would highly recommend!
