Constant Voltage Digital Residual Chlorine Dissolved Ozone Chlorine
Dioxide Sensor
>>Overview
The instrument consists of signal measurement, processing, display,
and panel controls. By applying a specific negative voltage
amplitude between the polarized electrode and reference electrode,
this device selectively allows residual chlorine, chlorine dioxide,
and ozone concentrations to participate in the reaction. These
substances undergo electrochemical reactions at the cathode of the
electrode, generating current signals proportional to their
respective concentrations. Through collection and analysis of these
current signals, the instrument calculates the concentrations of
residual chlorine, chlorine dioxide, and ozone. Key features
include:
▪ High selectivity
▪ No replacement parts required
▪ Minimal maintenance
▪ Long electrode lifespan
▪ High reliability
This product is widely used in drinking water treatment plants,
distribution networks, swimming pools, industrial wastewater
systems, and cooling water circulation systems for continuous
monitoring and control of residual chlorine, chlorine dioxide, and
ozone levels in water.
