Corrosion measurement of the environment

Per standard ISA-S71.04, “reactivity monitoring" provides a quantitative measure of the overall corrosion potential of an environment. Freudenberg Filtration Technologies offers corrosion monitoring in 2 options, passive and online:

Passive corrosion measurement

Passive monitoring

ChemDetect Coupons

Specially prepared copper and silver coupons are exposed in the operating environemnt for 30 days, and then analyzed in our laboratory by coulometric reduction. A report is provided showing the G-class corrosivity level per ISA-S71.04 standard.

Realtime corrosion monitoring

Online monitoring

ChemWatch

Copper and silver electronic sensors monitor the environment in real time, providing corrosivity levels and charts by the minute, allowing the user to react immediately in case of a rising corrosivity level in the room.

Chemical media testing

Different laboratory methods allow us to calculate the remaining lifetime of alumina based pellets, which is critical to identify the right time to replace the media. ​Freudenberg Filtration Technologies has multiple laboratories worldwide which offer:​

Remaining Lifetime Analysis (RLA): A small pellets sample is collected from the Gas Phase System operating in the field and sent to our laboratory for analysis. A report is then showing the remaining lifetime in percentage and moisture content. ​

Recurrent sample analysis and corrosion measurement are recommended, as gases and concentrations typically vary during the course of the year.
