Analog Chlorine Sensors
For free and total chlorine
The electrochemical WTW chlorine sensors can be applied for measurements in drinking water or swimming pools. Connectable via MIQ/IDS module to the IQ Sensor NET.
We would like to inform you about the application range on our website.
Sensor Overview and Specifications
Three sensor models are presented visually, each depicted as a cylindrical probe with a protruding tip. Key dimensions are indicated: overall length approximately 200 mm, with a tip section of approximately 25 mm.
