Chlorine dioxide sensor

The DULCOTEST sensor family for chlorine dioxide offers two types of sensors with different measuring ranges. Each series contains different types for different measuring ranges. We offer the CDE2 series of chlorine dioxide sensors for the control and regulation of clean water, such as drinking water disinfection. We offer the CDP1 series to quickly adjust the chlorine dioxide content of the bottle cleaning line. The innovative sensor type CDR1 can be used for contaminated water such as drinking water, cooling water and raw water to generate wastewater.


  • CDE Series: Surfactant-free potable, industrial and process water with slow temperature changes
  • CDP Series: Bottle washing plant and other applications with surfactant addition and rapid temperature changes
  • CDR series: contaminated industrial water and process water, water containing surfactants, cooling water, irrigation water, low contaminated wastewater, hot water
