CORROSION MONITORS

Atmospheric Corrosion Monitors for Electronic Equipment Rooms

Reactivity Monitoring

Airborne molecular contaminants damage electronics, circuit boards, and components. The damage from corrosion can cause downtime in production, costly repairs, and equipment failure and replacement in worst-case scenarios.

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. Passive monitoring involves installation of a one-time use coupon that accumulates corrosion over a 30-day time period.

Purafil OnGuard Smart Corrosion Monitor

The Purafil OnGuard® Smart (OGS) Atmospheric Corrosion Monitor indicates the level of corrosion before severe damage occurs, preventing costly downtime and maintenance repairs. The OnGuard’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 control system. The latest generation of OnGuard monitors now includes a room pressure sensor, and Wi-Fi capabilities.

Features

• Tracks peaks and trends to determine the level of corrosion
• Measures temperature, relative humidity, and room pressure
• Low maintenance: Sensors remain reliable until reaching 4000 Angstroms of cumulative corrosion
• Direct interface provided by the backlit LCD and keypad
• Remote power from network cable (PoE)
• 4-20mA connection for existing facility management systems or distributed control systems (DCS)
• Accurate within ± 1% of full span

Benefits

• Indicates the level of corrosion before damage occurs, preventing costly repairs/downtime
• Ethernet and Wi-Fi enabled
• Easy remote access to data and graphs
• RoHS compliant
• Measures corrosion, room air pressure, temperature, and relative humidity on a continuous basis
• Provides incremental and cumulative corrosion data
• Easy to install
• Long service life
• Readings correspond to ISA Standard 71.04-2013

Purafil OnGuard Lite Corrosion Monitor

The Purafil OnGuard® Lite provides a simple indication of a corrosion problem in your facility. This new monitor uses a silver sensor to identify if the atmosphere is corrosive enough to cause problems with equipment reliability. Silver is the most sensitive metal for corrosion monitoring.

Features

• LED corrosion indicator light
• Simple peel and stick installation
• Silver corrosion sensor
• Compact design

Benefits

• Simple pass or fail result
• Corresponds to ISA Standard S71.04-2013
• No maintenance
• RoHS compliant
• No lab testing required

Purafil OnGuard 4000 Corrosion Monitor

The Purafil ONGuard 4000 (OG4) Atmospheric Corrosion Monitor indicates the level of corrosion before severe damage occurs, preventing costly downtime and maintenance repairs.  The OG4’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 transmit to a process control system.

Features

• Measures corrosion, temperature, and relative humidity on a continuous basis
• Direct interface provided by the backlit LCD and keypad
• Remote power from network cable (PoE)
• 4-20mA connection with existing facility management systems 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

Benefits

• Indicates the level of corrosion before severe damage occurs
• Prevents costly repairs and production downtime
• Tracks peaks and trends to determine the level of corrosion
• Easy access to data and graphs
• Readings correspond to ISA Standard S71.04-2013
• Low maintenance: Sensors need replacement at 4000 Angstroms of cumulative corrosion growth
• RoHS compliant
