How is chlorine dioxide in water measured online? Online, continuous Chlorine Dioxide Analyzers and Controllers make up the DioSense range, which utilizes the best and most recent chlorine dioxide sensors available worldwide.
The DioSense chlorine dioxide sensors are membraned electrochemical sensors that don’t respond to chlorine, use no reagents, are incredibly stable and have less maintenance and reduced maintenance costs.
ClO2 is often used in challenging environments where sample preparation is key to making the sensors work reliably and for a long time between maintenance. Pi specializes in sample preparation.
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 design means that no reagents or buffers are required at all and calibration is a simple one point (no zero required) operation.
The DioSense chlorine dioxide analyzer is used in many applications from hospital water treatment to agricultural produce washing often as part of a chlorine dioxide dosing control regime. Capabilities including remote access via the mobile phone network using the Internet of Things MQTT communications protocol and full ClO2 dosing control, mark the DioSense as the chlorine dioxide analyzer of choice for many ClO2 generator suppliers.
Although it contains the word ‘chlorine’, there are distinct chemical differences between chlorine dioxide and what is normally referred to as chlorine disinfectant (hypochlorite).

While chlorine disinfectant is used the world over and is effective at maintaining drinking water safety, chorine dioxide does have a number of advantages:
When surface waters have taste and odor problems, chlorine dioxide can be an ideal primary disinfectant. Effective at concentrations as low as 0.1ppm and across a wide pH range, chlorine dioxide effectively penetrates bacterial cell walls to rapidly cause cell death. Industrial water applications (e.g. hot water loops, food washing) often use chlorine dioxide because of this.
Chlorine dioxide, when stored and handled properly, is perfectly safe to use. Like many disinfectant chemicals, chlorine dioxide has the potential to be harmful; this is what makes them effective at their intended purpose, and so prolonged exposure, contact or consumption is to be avoided.
