The Residual Chlorine Analyser is buffer and reagent free, meaning it has a low total cost of ownership and with maintenance intervals at 6 or even 12 months The CRIUS 3500 is fast becoming the instrument of choice for the engineer who wants the best residual chlorine analyzer at the best price.

The CRIUS 3500 offers a vast array of communication protocols including Bluetooth, TCP/IP (with webserver), USB, RS485, TTL, Relays and 4-20mA outputs. It is possible to interface and control the CRIUS 3500 Residual Chlorine Analyzer remotely, enabling data, alarms and setup information to be sent direct to your computer via a GSM/GPRS modem. Despite all of the additional functionality that this unit has to offer, the purchase costs are less than, or comparable to, its competitors. If you then add in the cost savings of a truly automatic (no operator present) calibration system, some will achieve a replacement payback of only a few months.

The membraned polarographic probe, on the Total Chlorine Analyser, the Free Chlorine Analyser, and the Chlorine Dioxide Analyser is enhanced with a third, reference, electrode which eliminates zero drift. pH correction is often not required at all. A Total Chlorine Analyzer, Chlorine Dioxide Analyzer, and Free Residual Chlorine Analyzer are all available.
