Endress+Hauser TOCII CA72 total organic carbon analyser

Click2Contact

The TOCII CA72 total organic carbon analyser is a high-temperature TOC analyser that uses an exchangeable combustion unit to reduce maintenance downtime by 80% and a rotating shaft filter to eliminate blockages by particles larger than 200 microns.

The CA72 analyser uses high temperature to break down complex carbons enabling the TOC/TC (total organic carbon or total carbon) levels in wastewater to be monitored. Measuring times are 7-12 minutes in batch mode and 3-15 minutes in continuous mode, and the measuring range: is 0.25 to 12,000 mg/L. The instrument is optimised for applications with varying pH values and very high salinity.

With the CA72, the combustion unit can be easily removed and replaced. This allows the instrument to quickly start up again, reducing combustion unit maintenance time by up to five hours. The exchangeable combustion unit now gives customers the opportunity to do quick proactive maintenance reducing the chance of the system needing maintenance during a critical measurement time. To meet the set regulatory standards, TOC analysers must measure all organic carbon particles smaller than 200 microns. To eliminate the possibility of particles larger than 200 micron blocking the filter, Endress+Hauser has designed a rotating shaft filter that allows the water and smaller particles to pass through, with the larger material being diverted to waste. This design keeps the filter free of blockage and eliminates the need for filter replacement.

Endress+Hauser’s robust CA72 is suited to the monitoring of industrial wastewater and can provide alarms when preset limit values are exceeded.
