The larger battery makes this a good unit compared to those that run AA batteries. I test for hours straight with this meter without battery replacement. Very accurate and past the drop test a couple times.

Worked fine, used for home Natural Gas furnace. I replaced a defective valve.I used this after to measure the pressure on the outlet of the new valve.If you want the measurement in 'inches of water column (WC)', you set the manometer units to 'inH20'

so i have a obvious 410a refeidgerant leak I can see it on evap coil…i put this thing right over the oily refeidgerant leak and it does NOTHING…however i run it over my arm or skin and it goes off. It is either a total dud and I got a lemon or this product is trash.

it is a good little manometer that reads clearly and stable.it has a back light and can be zeroed out. i like the small size and the fact that i can measure .05" or .04" water column and it doesn't just drop out below.2:. it doesn't "walk" away from zero

It drifts around, must continually rezero.
