• RS485 digital transmission interface, standard Modbus communication protocol. • High measurement accuracy, fast response time, high reproducibility. • It can be used continuously on site for 9 months without calibration or maintenance. • The measurement value is not affected by the flow rate and pressure, and the maximum pressure resistance is 10 bar. • Directly pipe insertion. • Automatic temperature compensation.

This sensor differs from traditional electrodes. It is manufactured with cutting-edge Swiss technology, using silicon nitride-coated photopolymer films and silicon crystal semiconductors as conductive elements. It has built-in chlorine and temperature probes. Through MEMS technology, microelectronic components are injection-molded and encapsulated. As the free chlorine or chlorine dioxide concentration in the water sample changes, the sensor generates different current intensities, which are processed by a regulator and signal amplifier, and converted into standard Modbus RS485 signals.

Measurement range: 0~5mg/L Resolution: O.Olmg/L Response time: Less than 30s after polarization is completed Accuracy (@ 25°C pH7.2): 0-2mg/L: ^O.lmg/L, the absolute error is ±0.01mg/L; 0.1^X^2mg/L, ±5% of the measured value or ±0.03mg/L (whichever is greater) 2-5mg/L: ±5% of the measured value or ±0.25mg/L (whichever is greater) pH range: 5-9, the membrane head will be damaged if it is below 5 Sample flow rate: 12-30L/H, in the flow cell Temperature compensation: PT1000, built-in integrated automatic compensation Storage temperature: 0-40°C (no condensation) Output interface: RS485 (standard...

It can directly communicate with PLC, data acquisition instrument, and touch screen, and monitor the residual chlorine value in the water in real time and online. 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.
