Chinese wholesale Optical Dissolved Oxygen Sensor - Online Membrane Residual Chlorine Meter T6555 – Chunye

Function

Online residual chlorine meter is a microprocessor-based water quality online monitoring control instrument.

Typical Use

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 residual chlorine, pH and temperature value in aqueous solution.

Mains Supply

85~265VAC±10%,50±1Hz, power ≤3W;
9~36VDC, power consumption≤3W;

Measuring Range

Residual Chlorine: 0~20ppm;
pH: -2~16pH;
Temperature: 0~150℃.

Features

1.Large display, standard 485 communication, with online and offline alarm, 235*185*120mm meter size, 7.0 inch large screen display.

2.The data curve recording function is installed, the machine replaces the manual meter reading, and the query range is arbitrarily specified, so that the data is no longer lost.

3.Historical curve: The residual chlorine measurement data can be stored automatically every 5 minutes, and the residual chlorine value can be stored continuously for a month. Provide “history curve” display and “fixed point” query function on the same screen.

4.Built-in various measurement functions, one machine with multiple functions, meeting the requirements of various measurement standards.

5.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.

Electrical connections

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.
