OnGuard™ Smart
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™ Active Monitoring
The Purafil OnGuard™ Smart range provides continuous, real-time monitoring of air quality conditions that can contribute to atmospheric corrosion in critical environments. By measuring corrosion reactivity levels alongside temperature, humidity, and room pressure, the system delivers accurate insight into the effectiveness of air treatment and chemical filtration strategies. Designed for applications such as data centres, control rooms, industrial facilities, water and wastewater plants, museums, and other sensitive environments, OnGuard Smart helps identify corrosive conditions before they lead to equipment damage, unplanned downtime, or costly repairs. With easy installation, remote data accessibility, and optional Modbus connectivity for integration with building and process control systems, the OnGuard Smart range supports proactive asset protection and informed maintenance decisions.
