MEASUREMAN Diaphragm Type Capsule Low Pressure Gauge, 2-1/2" Dial, 1/4" NPT Lower Mount, Adjustable, 0-5Psi

The gauge seemed well built, as it’s a very sensitive gauge it is also delicate in some regards. Was able to thread right onto a 1/4 pipe reducer to 1/2” and test pressure on my gas line for my furnace.

I really have no way to test the accuracy but it is definitely precise. I am using to compare air pressure before and after a filter to know when it needs replacement. Very handy.

A necessity for converting a natural gas shop heater to propane to properly set the burner regulator pressure.

Nice small gauge for the money. Should help me monitor the condition of the air compressor on our septic system.

Currently in the process of adding a furnace and central air to my garage mahal. I ran about 60' of 1" polyethylene pipe 18" deep and wanted a solid pressure test before I began the backfill.I had a cheap gauge on the stub up to garage and a more expensive, liquid filled one I purchased at Amazon at the stub up exiting the house.Long story short, 48 hours later the newer gauge was reading 8 psi while the cheaper gauge was reading 10. Rather than moving forward and having to unearth an 18" buried line in the future, I decided to get this gauge.I installed it on a tee after a shut off in the basement to check the whole new run of pipe. I pumped the line up to 10 psi and it's still holding strong. I then took the other gauge and setup a test rig and pumped it up and submerged under water to find a very small amount of bubbles coming from where the brass fitting meets the gauge housing.I also did a pressure test on this gauge and it held 10psi for 2 days before I decided to trust it. It's a little more money than the rest, but a diaphragm gauge is worth the extra coin.

Installed alongside a vaporstat on my boiler to help dial in low PSI cycles. Works nicely, looks good. No complaints!

Works great

I hooked this to my propane gas line for my dryer and started to leak thru the diaphragm. I wrote to the vendor and even though the period for me to return it has passed, the vendor decided to honor the warranty. Now, this is the type of service you want. Customer service team have to gave them a 10. Received the new one and it is working perfectly. Customer service was fantastic resolving, 5 star.
