Dabeco - Model DAW2407 -Digital Chlorine/Chlorine Dioxide Probe for Tap Water

As the free chlorine or chlorine dioxide concentration in the water sample changes,the sensorgenerates different current intensities, which are processed by a regulator and signal amplifier, and converted into standard Modbus RS485 signals.

The sensor does not require the replacement of reagents during use, and is easy to maintain, ensuring the stability, reliability, and accuracy of the instrument`s long-term operation. It can be used in water plants, rural drinking water, water stations, secondary water supply, and other fields.
