Measure chlorine dioxide with optimal precision and accuracy in drinking water, institutional hygiene, cooling tower and food manufacturing applications.


Sister product to the ChlordioX Plus, the ChlordioXense utilises the same EPA approved method for measuring Chlorine Dioxide and is now approved as an alternative testing method for public water drinking supplies under the Clean Water Act.

Chlorine Dioxide has a number of advantages as a disinfectant, but measurement methods in the field can be difficult to carry out repeatably. The ChlordioXense uses unique disposable sensor technology to remove operator dependence and deliver accurate Chlorine Dioxide results.

Among the features are:

  • Simple test procedure – fill the sample vessel, insert the sensor and close the lid
  • Results available in less than one minute – no lengthy measurement times
  • Waterproof USB connection – download data without any additional software and upload software updates

Supported with a full range of calibration check standards and technical advice, the ChlordioXense is an integral part of any Chlorine Dioxide control programme. To enable customers to make immediate checks on instrument performance in the field, FREE check standards are now included with this kit.

  • ChlordioXense Instrument
  • USB Cable
  • 100 CDX sensors including calibration chip
