Western Enterprises VN-650 Flowmeter Nitrogen Purging Regulator w/650 PSI Test Pressure

Had the 500, and now I needed more for new co workers, I saw they had a 650 and Im glad I saw because I love the higher test pressure. Been using the 500 for 5 years now and plan on using this new one for years to come

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

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

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

La mejor herramienta, ahorras tiempo y fácil de usar , la recomiendo
