Customer Reviews
Brilliant bit of kit. Much easier to carry around than my old U gauge manometer, and the backlit screen is a lifesaver in dark boiler cupboards.
Spot on for HVAC differential pressure testing. The multi-unit display means I don't have to convert readings in my head anymore.
Good solid gas pressure tester. Accurate readings and easy to zero. The included hoses could be slightly longer, but they do the job.
Excellent value compared to the Kane digital manometer I used to have. Does exactly the same job for a fraction of the price.
Very compact and easy to use. The data hold function is great when you're in an awkward spot and can't see the screen while testing.
Does what it says on the tin. Good low pressure gauge for boiler work. Battery life seems decent so far.
Swapped my analogue manometer for this digital one and haven't looked back. Much faster to get a reading.
