NFPA 99 Compliant Regulator Flowmeter with Alarm Gauge



After many requests for a less expensive purge alarm with a regulator flowmeter, we are happy to announce this NFPA 99 Compliant assembly.

The LON2 purge alarm gauge is a Standard Pressure Gauge with built-in Audio and Visual. When the tank pressure reaches 500 psi or less, the gauge triggers an audible buzzer and a flashing red light.

The bottom connection is 1/4-inch male NPT and now includes the A333-N2R adapter FREE at no additional cost!
