Residual Chlorine Analyzers including a Free Cl2 Analyzer, Total Chlorine Analyzer and Chlorine Dioxide Analyzer are available. The CRIUS 3500 Bufferless Residual Chlorine Monitor is the first of its kind in the world to offer automatic calibration as an option. Cleverly engineered and using state of the art electronics the CRIUS 3500 is able to save customers considerable sums of money by autocalibrating at user defined time intervals.

The Residual Cl2 Analyzer is bufferless and reagent free, meaning it has a low total cost of ownership and with maintenance intervals at 6 or even 12 months The Bufferless Chlorine Monitor is fast becoming the instrument of choice for the engineer who wants the best chlorine monitor at the best price.

The CRIUS 3500 offers a vast array of communication protocols including TCP/IP (LAN), USB, RS485, Modbus, TTL, Relays and 4-20mA outputs. It is possible to interface and control the CRIUS 3500 Residual Chlorine Monitor 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 instrument has to offer, the purchase costs are less than, or comparable to, its competitors. Some will achieve a replacement payback of only a few months, on their currently installed Free or Total Cl2 Monitors.

The membraned polarographic probe is enhanced with a third, reference, electrode which eliminates zero drift. pH correction is often not required at all.
