Real-Time Corrosion Monitoring
Quantitative Corrosion Assessment
User-Friendly and Robust Design
Long Sensor Life
When the minutest layer of corrosion builds up on the circuit surfaces of electronic systems at data centres, server rooms, control rooms, it aggravates electrical resistance and decrements equipment performance. Thus, installation of corrosion monitoring device is recommended to ensure early detection of corrosion potential, which can improve electrical systems performance.
Atmospheric Corrosivity Monitor provides qualitative and quantitative details of the overall corrosion potential of an environment (room) through copper and silver sensors.
It also measures and monitors the room temperature, relative humidity and the differential pressure (optional). It is based on Quartz Crystal Microbalance (QCM) technology. It measures the weight gain as a consequence of corrosion built up on the copper and silver plated sensors surfaces. The weight gain is translated to film thickness and the corresponding corrosivity classification level. The measurements are extrapolated in 24 hours for 30 days to know the severity level as per ISA standards.
Bry-Air Atmospheric Corrosivity Monitor diagnoses the corrosion of an environment according to the ANSI/ISA-71.04-2013 outlining the severity of corrosion from G1 (mild) to Gx (severe) environment. Reactivity monitoring can be used to characterise the destructive potential of an environment. Measurement of the thickness of corrosion film provides an excellent indication of the type(s) and level(s) of all corrosive gases present in the local environment.
Often it is seen that the environmental threats posed by fire, power, temperature, humidity and airborne particulates have long been recognized and successfully addressed in the server-room environment, but the corrosive potential of the air has been largely ignored. Even extremely low levels of contaminant gases at the ppb level corrode and damage the sensitive electronic cards in your servers. Excessive corrosion often leads to electronics warranty non-compliance, circuit board failure, ghost signalling, and even complete failure of electronics components.
Environments with higher atmospheric and air contamination require greater attention to air quality management. The interactive result of temperature variations and humidity with the gaseous contaminants has the potential to increase the threat of air corrosion, providing greater reasons for close monitoring of the immediate environment of IT infrastructure. All companies dealing with sensitive IT infrastructure such as data centres, server rooms, and control rooms, as a core part of their operations, need to implement a comprehensive checking and monitoring mechanism for the corrosion potential of the gases inside their facility. The ISA standards define or characterise environments in terms of their overall corrosion potential.
Based on the proven Quartz Crystal Microbalance (QCM) technology in which frequency output changes due to changes in weight. The stable digital output is not prone to drifts or errors and can be easily processed. The unit utilises copper and silver-coated quartz crystal microbalances and monitors the weight gain as a consequence of corrosion built up on the metal surfaces. The weight gain is translated to film thickness and the corresponding corrosion classification level.
ACM model BCM232 monitors the overall reactivity levels of gaseous airborne contaminants present. Reactivity Monitoring provides an exact and dependable way to evaluate the corrosivity potential of indoor air and also the effectiveness of installed filter systems.

Atmospheric Corrosivity Monitor enables measurement of the corrosion potential of an enclosed environment with ease and accuracy on a real-time basis. It is used across various industries that include:
An Atmospheric Corrosivity Monitor is a monitoring system that provides a real-time, quantitative indication of the overall corrosion potential of an environment. It helps assess whether the surrounding atmosphere poses a risk to sensitive electronic equipment.
The ACM measures the overall corrosivity of the environment rather than measuring the concentration of one specific gas. It provides a direct indication of the atmosphere’s potential to cause corrosion.
The monitor can support assessment of atmospheric corrosion severity, while ISA-71.04 classification provides the framework for interpreting corrosion conditions. For formal classification, the measurement method and applicable assessment procedure should be followed as specified for the particular application.
The ACM measures the resulting overall corrosion potential, making it useful in environments where several contaminants may be present simultaneously. This is particularly relevant to industrial facilities where mixed-gas exposure can affect electronic equipment.
It can be used in environments where sensitive electronics are exposed to potentially corrosive atmospheres, including power plants, oil & gas facilities, chemical plants, sewage and wastewater treatment plants, pulp & paper mills, data centers, semiconductor facilities and other industrial control environments.
Yes. These are important applications because DCS, PLC, SCADA, protection relays and other control electronics can be vulnerable to corrosive gases entering through ventilation systems, door gaps and other pathways.
