24V Chlorine Dioxide Analyzer Used For Sewage And Wastewater Disinfection

Introduction

Among the commonly used disinfectants, the concentration of chlorine dioxide required at the same time is the lowest. After being dissolved in water, chlorine dioxide basically does not react chemically with water, nor does it exist in a dimerized or polymerized state. Its diffusion speed and permeability in water are faster than chlorine, especially at low concentrations. The ADS2-U3D-CD7 chlorine dioxide analyzer is a single-parameter instrument. It is compatible with DRFN's membrane-covered chlorine dioxide sensors.

Advantages Of Chlorine Dioxide Analyzer

1. Two settable SPST relays. The setting objects include alarms for the high and low values of the measurement parameters, the control of the cleaning cycle of the sensor. The warning of the working environment temperature.

2. A two-wire RS485 interface, the communication protocol is MODBUS RTU. The chlorine dioxide controller supports JSON text data format.

3. All the configuration entered by the user is kept indefinitely, even if there is no power, the data will not be lost.

4. 128*64 black and white graphic dot matrix screen, and the display backlight provides always on and energy-saving mode selection.

5. It has time and historical data recording functions to meet higher data management requirements.

6. Menu password can be set to facilitate hierarchical management.

Applications Of Chlorine Dioxide Analyzer

The instrument is used for disinfectant measurement in drinking water, swimming pool and industrial cooling water, water plant effluent and municipal pipe network monitoring.
