Online chlorine dioxide meter is a microprocessor-based water quality online monitoring control instrument.
This instrument is widely used in online monitoring of water supply, tap water, rural drinking water, circulating water, washing film water, disinfectant water, pool water. and other industrial processes. It continuous monitoring and control chlorine dioxide and temperature value in aqueous solution.
85~265VAC±10%,50±1Hz, power ≤3W;
9~36VDC, power consumption≤3W;
Chlorine dioxide: 0~20mg/L; 0~20ppm;
1.Large display, standard 485 communication, with online and offline alarm, 98*98*130mm meter size, 92.5*92.5mm hole size, 3.0 inch large screen display.
2.Historical curve: The chlorine dioxide measurement data can be stored automatically every 5 minutes, and the residual chlorine value can be stored continuously for a month. Provide standard solution calibration and field calibration.
3.Built-in various measurement functions, one machine with multiple functions, meeting the requirements of various measurement standards.
4.The design of the whole machine is waterproof and dustproof, and the back cover of the connection terminal is added to extend the service life in harsh environments.
5.Panel/wall/pipe installation, three options are available to meet various industrial site installation requirements.
Electrical connection The connection between the instrument and the sensor: the power supply, output signal, relay alarm contact and the connection between the sensor and the instrument are all inside the instrument. The length of the lead wire for the fixed electrode is usually 5-10 meters, and the corresponding label or color on the sensor Insert the wire into the corresponding terminal inside the instrument and tighten it.
