The Purafil OnGuard Smart(OGS) 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 OGS's copper and silver sensors measure the rate of corrosion in real-time. An internal data logger stores the results to access through the internet or directly transmits to a process control system. The latest generation of OnGuard monitors now includes a room pressure sensor, and Wi-Fi capabilities. Ideal for control rooms, server rooms, motor control centers, rack rooms or other areas where corrosion is a concern, the OG4 allows action to be taken before problems develop.
The OGS comes with two quartz crystal microbalance (QCM) sensors, one that is plated with copper and anoth¬er with silver. The QCM is used to measure the corrosive film that results from the environment. This highly sensitive method of measurement will indicate contaminant levels at or less than one part per billion (1 ppb). The corrosion film thickness is measured and recorded in Angstroms (Å). This measurement corresponds directly to ISA Standard S71.04-2013.
