DioSense – Chlorine Dioxide
Online, continuous Chlorine Dioxide Analyzers and Controllers make up the DioSense range which utilizes the very latest and best chlorine dioxide sensors available in the world today. There are two sensors in the range. The first 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 second is a non membraned 3 electrode sensor that is capable of high temperature and high pressure operation.
Key Benefits
- Amperometric sensors – continuous online chlorine dioxide ppm measurement
- No chemical reagents – lower cost of ownership
- Stable and reliable – excellent process control
- Suitable for all potable and process water
- Up to 6 months between maintenance
- No interference from residual chlorine
- Tolerant of water containing detergent
