OnGuard Lite Help

The OnGuard lite is a stand-alone, battery operated corrosion monitor that does not require lab analysis or sophisticated equipment for evaluation.

Once activated, the unit blinks a green light (PASS) as long as the environment maintains corrosion free air.

If the monitor blinks a red light (FAIL), air quality is corrosive, and your equipment may be at risk for corrosion related failure. Contact Purafil by phone or web so we can provide a solution before costly damage occurs.
