ONGUARD 4000The Purafil OnGuard 4000 (OG4) Atmospheric Corrosion Monitorindicates the level of corrosion before severe damage occurs, preventing costly downtime and maintenance repairs. Reactivity monitoring is an accu- rate 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. An internal data logger stores the results to be accessed through the internet or directly transmit to a process con-trol system. Ideal for control rooms, server rooms, motor control centers, rack rooms, or other areas where corrosion is a concern, the OG4 prompts preventive action beforeserious problems develop. Benefits•Indicates the level of corrosion before severedamage occurs• Prevents costly repairs and production downtime•Tracks peaks and trends to determine the level ofcorrosion• Easy access to data and graphs• Readings correspond to ISA Standard 71.04-2013•Low maintenance: Sensors need replacement at 4000Angstroms of cumulative corrosion growth• RoHS compliant Features•Measures corrosion, temperature, and relative humidityon a continuous basis•Direct interface provided by the backlit LCDand keypad• Remote power from network cable (PoE)•4-20mA connection with existing facility managementsystems or distributed control systems (DCS)• AA battery-powered for remote or inaccessible areas• Provides incremental and cumulative corrosion data• Long service life• Accurate within ± 0.5-1% of full span Principle of OperationThe OG4 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 corrosivefilm that results from the environment. This highly sensitivemethod of measurement will indicate contaminant levelsat or less than one part per billion (1 ppb). The corrosionfilm thickness is measured and recorded in Angstroms (Å).This measurement corresponds directly to ISA StandardS71.04-2013.
