Active Monitoring
Reactivity monitoring is an accurate and reliable method of evaluating the quality of makeup and recirculation air in a controlled environment. Active monitoring involves constant feedback of data measuring the type and level of corrosion, temperature and humidity.


OnGuard 4000
Track the level of corrosion before severe damage occurs, preventing costly downtime and maintenance repairs. The OnGuard 4000 measures the overall reactivity level of air contaminants, temperature, and humidity in a controlled environment. Wall installation takes only minutes and data is accessible anytime, anywhere.

OnGuard Lite
The OnGuard Lite provides a simple Pass/Fail indication of a corrosion problem in your facility. This new monitor uses a silver sensor to identify if the atmosphere is corrosive enough to cause problems with equipment reliability.

OnGuard Smart
The next generation of the OnGuard now features a room pressure sensor. The OnGuard Smart measures the overall reactivity level of air contaminants, temperature, and humidity in a controlled environment. Wall installation takes only minutes and data is accessible anytime, anywhere.
