"These are the best chlorine dioxide sensors we've ever used and we've tested most"
, Alistair Cameron, UK

The DioSense range of Chlorine Dioxide Analyzers, and Chlorine Dioxide Monitors utilise the very latest and best chlorine dioxide sensor available in the world today. It is a membraned device which is insensitive to chlorine, uses no reagents, is extremely stable, and has reduced maintenance and reduced whole life costs.

The DioSense sensors and flow cells are available with different controllers giving you the same great performance with different communication, display, and control options. With the DioSense range of residual chlorine dioxide analyzers, you get everything that you need - and nothing that you don't.

The DioSense Residual Chlorine Dioxide Monitor is used in many applications requiring the measurement of chlorine dioxide concentration for chlorine dioxide monitoring or residual chlorine dioxide dosing control.

Autoflush

As described in a seperate brochure, the DioSense can come equipped to automatically clean itself at user defined intervals. The Autoflush is particularly useful in food preparation, pulp and paper, and many applications where there is likely to be a build up of solids in the sample. The DioSense range of chlorine dioxide monitors are particularly resistant to tensides and are therefore particularly useful in food washing applications.

Anywhere you have a requirement to measure residual ClO2 is a suitable application for the DioSense. The DioSense chlorine dioxide monitor range is particularly suited to working in sites where reliability and ease of use are most important.

Multi-Sensor Systems

The whole range of DioSense Residual Chlorine Dioxide Monitors and Controllers can be fitted with additional sensors such as chlorite or pH. Please ask your local distributor for more details.

Cost of Ownership

With its reduced maintenance, reduced calibration and reduced spares requirements the DioSense ClO2analyzers are undeniably the most cost effective ClO2 analyzers available.

According to the EU Directive 98/83/EC, the operators of waterworks must ensure that the levels of harmful chlorite (ClO) in drinking water remain below the specified limit of 0.2 mg/l. The monitoring of Chlorite at the same time as Chlorine Dioxide is also a European requirement.

In most situations the ClO2 Monitor should be able to control the dosing of ClO2 by adjusting flow rates, pump rates, or valve positions automatically to maintain the residual chlorine dioxide setpoint. Chlorine dioxide analyzers are often used to monitor the residual ClO2 in difficult ‘dirty’ applications such as in hospitals or the food industry. In these cases, in order to maintain an appropriate Chlorine Dioxide residual it is necessary to automatically clean the sensor using an autoflush.

Principle of Operation

The membraned amperometric chlorine dioxide sensor is a two electrode sensor which operates at an elevated applied potential which in turn eliminates zero drift. Its unique design means that no reagents or buffers are required at all and calibration is a simple one point (no zero required) operation. In addition to the state of the art amperometric chlorine dioxide sensor the DioSense range of controllers has all the functionality that you need. Choose from the CRONOS, CRIUS® or CRATOS controller to give you the highest quality chlorine dioxide monitor, with all the functionality you need, at the lowest price possible. This means that you pay for everything that you need, and nothing you don't, without sacrificing the quality of measurement.

Residual Chlorine Analyser | Free Chlorine Analyser

For pH compensation to be valid it must be done with the highest quality pH sensors and with chlorine sensors that have a reduced susceptibility to varying pH, such as those used in the HaloSense range of residual chlorine analysers. The HaloSense range of Residual Chlorine Analysers are used in many applications requiring the measurement and control of residual chlorine levels.
