A must have for pressure testing and nitrogen purge. The 650 will get you pressure tests on your VRVs

All settings work like theyre supposed to and it works flawlessly.

Was a great just a little long to pressure check but other then that great

Best nitrogen regulator Ive used

Well made easy to use

Set and forget for braze shield gas, Purge and pressure test, this thing is built like a tank.

Product is great it saves time on swapping out flow meter from regulator

Best flow meter on the market. This meter is awesome for pressure testing hvac systems, and for purging while brazing linesets.
