Reliable online measurement of free (effective) chlorine – with the versatile DULCOTEST® sensors.
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.
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.
Your benefits
Five different sensor ranges and numerous different versions deliver the following benefits: Use with a wide range of water qualities (pH, salt content, temperature, chemical and contamination load), use in combination with many disinfection processes: chlorine gas, sodium hypochlorite, calcium hypochlorite, electrolysis, use in a wide measuring range of 0.01 to 1,000 mg/l.
Precise, real-time amperometric measurement for efficient process control (short response time)
Amperometric measuring means no clouding or discolouration
Stable zero point
Integrated temperature compensation eliminates faults caused by influence of temperature
For sensors with diaphragm-covered measuring electrodes: Reduced dependence on flow, substances in water and film-forming media. Diaphragm-covered measuring electrodes embedded in an electrolyte ensure long service life. This maintains optimum measuring conditions regardless of process conditions. Low-cost maintenance thanks to easy diaphragm cap changes.
