"ISEmax CAS40D is an ion-selective electrode system for the continuous measurement of ammonium, nitrate, potassium and chloride. The system consists of a sensor based on the Memosens protocol, electrodes and the Liquiline CM442 transmitter. It is mounted on the basin rim. Up to three ion-selective sensors simultaneously measure nitrate, ammonium and, where applicable, other variables in the aeration basin.","Your benefits","Reliable, cost-saving unit:","- Nitrate and ammonium measured directly without the need for expensive","sample conditioning","- Ion-selectivity prevents interference from nitrite","- Optional potassium and\/or chloride measurement, also to compensate high","concentrations of interference ions","- Low operating costs since no reagent used","Versatile and flexible:","- Large measuring range 0.1-1000 mg\/l NH4-N and 0.1-1000 mg\/l NO3-N","Easy-to-use and safe:","- Installed directly on the basin rim, no measuring container or sample-","conveying pump required","- Low maintenance thanks to automatic flushing unit","- Membrane cap replacement every 6 months prolongs electrode service life","- Standardized communication via the Memosens protocol enables plug&play"
