Free-chlorine analyser – maintenance-free, consistently accurate readings

Australian instrumentation

supplier ProDetec now offers the new Sigrist free- chlorine analyser that self- cleans to ensure a consistent accurate reading of chlorine levels every time in seconds.

Perfect for the treatment of drinking water, says ProDetec, as well as water in beverage and food production and process water in various industries, the Sigrist AquaDMS Disinfection Measuring System helps technicians effectively optimise the chlorination of water.

The system can precisely measure chlorine levels over long periods of time because all sensors are equipped with an automatic sensor cleaning function called ASR. This function ensures that all the sensors are automatically cleaned at least once within a 24-hour cycle to deliver a precise reading of chlorine levels every time. The process removes coatings of organic and inorganic material from the sensors to provide zero point stability and no drift.

Plus, the automatic cleaning function eliminates the need for the Sigrist AquaDMS to be manually cleaned and the use of chemical additives. This saves both money and valuable time that can be directed elsewhere. Further, the system’s self- cleaning mechanism also allows installations to benefit from the convenience of longer calibration cycles.

ProDetec says as it is fast, efficient and highly reliable, the analyser allows the user to directly measure chlorine levels within the water in real time. This removes the need to send water samples to a lab and gives the technician precise and immediate control over chlorine levels so that they can be adjusted if necessary.

Compact and easy to install, the Sigrist AquaDMS Disinfection Measuring System is all encompassing. It includes an intelligent control system and flow regulator. The operator touch screen, sensor, assembly and wiring are pre-mounted on a panel. The control system features an easy to use touch screen and colour display that clearly illustrates values, alarm and status messages. The flow regulator ensures a stable flow of water through the system for the continuous accurate measurement of disinfectants.

The system is also flexible. As free chlorine measurements are affected by pH and temperature, an optional pH electrode can be integrated into the Sigrist AquaDMS. An input is also available for temperature as well as digital in and out.
