The application-based DULCOTEST sensors for free chlorine deliver precise measured values and a high degree of monitoring and process reliability in any disinfection application.
Free chlorine is the most important disinfectant in the world. This term is used to refer to the compounds Cl2 (elementary chlorine), HOCl (hypochlorous acid) and OCl- (hypochlorite).
Our product line of DULCOTEST sensors for free chlorine provides five product ranges optimised for different applications. Each product range consists of several types with different measuring ranges.
The proven diaphragm-covered standard sensor for free chlorine CLE3 is used to monitor or control all types of clear water, for example in the disinfection of potable water. The variant CLE3.1 is especially suitable for an excess of combined chlorine, providing the most accurate results in the calculation of combined chlorine from the measurement of total chlorine and free chlorine.
Sensors CLB2 and CLB3 are easy-to-operate, low-cost chlorine sensors without a diaphragm for clear water without pollution.
Sensor CLO1 is particularly suitable for in-line electrolysis
processes where unwanted compounds may be formed; sensor CLO2 is also ideal for hot water disinfection.
Sensor CBR1 can be used in contaminated water, even for high pH values of up to 9.5, for example in the disinfection of cooling water.
Sensor CLR1 has been optimised for the disinfection or washing of foodstuffs and tolerates contaminated water and chlorine concentrations of up to 1,000 mg/l.
