The OnGuard Smart corrosion-monitoring device incorporates a room pressure sensor and WiFi capabilities to provide a complete picture of the environment’s air quality with multiple connectivity options. In addition to measuring room pressure, the OnGuard Smart also monitors temperature and relative humidity. Most importantly, copper and silver corrosion corresponding to ISA Standard 71.04-2013 is measured via this company’s Quartz Crystal Microbalance (QCM) sensors. The OnGuard Smart can also alert an operator to a potential failure of electronics so action can be taken before failures occur. Data-logging and reporting capabilities provide diagnostic data to pinpoint problem areas or times so that issues can be resolved quickly. System data are captured in realtime, and are accessible remotely. — Purafil, Inc., Doraville, Ga.
