Because many contaminants are corrosive in nature (e.g., hydrogen sulfide and sulfur dioxide), reactivity monitors have long been used to gauge the quality of ambient air and to indicate the effectiveness of pollution control strategies.

Heartfil uses Purafil’s reactivity monitoring technique, which is passive in nature and involves the use of copper and silver Corrosion Classification Coupons (CCC).

The Purafil OnGuard 4000 (OG4) Atmospheric Corrosion Monitor indicates the level of corrosion before severe damage occurs, preventing costly downtime and maintenance repairs. Reactivity monitoring is an accurate and reliable method of evaluating the quality of air, characterizing the room environment, and evaluating the effectiveness of chemical filters.
The OG4’s copper and silver sensors measure the rate of corrosion in real-time.
