DULCOTEST CGE 3-mA

Pictures can differ from the selected variant.

Free chlorine sensor without disturbance by electrolysis processes and for stabilised chlorine.

Sensor for free and total available chlorine, such as derivatives of chloro(iso)cyanuric acid, without disturbance when used in swimming pools where disinfection is provided by electrolysis processes. For operation with controllers with 4-20 mA input

Description product group

Measured variable: total available chlorine, for instance disinfectant with organic chlorine, such as derivatives of chloro(iso)cyanuric acid
Measured variable: free chlorine without interference with the presence of cyanuric acid
Gold electrode to prevent faults by products from electrolysis processes where the electrodes are immersed directly into the sample water (without diaphragm)
Diaphragm-covered sensor (encapsulated) minimises faults caused by changing flow or substances in the water
Hydrophilic diaphragm guarantees the permeability of chloro(iso)cyanuric acid derivatives towards the measuring electrodes
The special reaction system of the electrolyte allows the total available chlorine to be determined and use at a high pH of up to 9.5
