Customer Reviews
Brilliant piece of kit. Replaced my old analogue u gauge manometer with this. The mbar readings are spot on for checking gas valves on combi boilers. Saves me loads of time.
Excellent gas pressure tester. The backlit screen is a lifesaver in dark airing cupboards. Highly recommend for any Gas Safe engineer.
Very accurate differential pressure gauge for HVAC work. The zeroing function is quick. Only dropped a star because the supplied hoses could be a bit longer, but standard tubing fits fine.
I use this digital manometer for automotive diagnostic work, checking DPF pressures. It's robust, easy to read, and the unit selection is very handy.
Great value for money compared to the big name brands. The accuracy is just as good, and it feels solid enough for daily van use.
Good air pressure meter. Simple to use and the hold function is useful when you're stretched awkwardly to reach a test point. Battery life seems decent so far.
Top rated digital manometer in my book. Next day delivery was exactly as promised. Essential tool for commissioning new heating systems.
