Online ORP Meter

1.Online ORP Meter Product Introduction

Online ORP Meter is used to monitor ORP value in chemical, environmental protection and food industries, and is used to measure ORP at different temperatures.ZS6 Online ORP Meter is an instrument capable of monitoring ORP online.It integrates ORP sensors and measurement module communication storage, which can quickly and accurately record key parameters in water.At the same time, the instrument supports extended water quality multi-parameter sensors, including but not limited to ORP, pH, dissolved oxygen (DO), conductivity, turbidity, temperature, ammonia nitrogen, etc.It can be combined and configured according to different needs and applications, and records and stores historical monitoring data and alarm history records, supporting historical data export.xlsx.The RS485 interface supports MODBUS-RTU communication protocol to facilitate users to communicate freely with PLC, DCS, configuration software, DTU and other devices to connect and transmit data.

2.Online ORP Meter application field

Online multi-parameter water quality detectors are widely used in the monitoring and control of various water bodies, including but not limited to the following fields:

1.Water plant: used to monitor the pH value, dissolved oxygen, turbidity and other parameters of tap water to ensure the safety and hygiene of tap water.

2.Groundwater monitoring: used to monitor the pH, conductivity, temperature and other parameters of groundwater in order to promptly discover and solve water quality problems.

3.River and lake monitoring: used to monitor the water quality of rivers and lakes, such as dissolved oxygen, turbidity, ammonia nitrogen and other parameters, so as to take pollution control measures in a timely manner.

4.Ocean monitoring: used to monitor the ocean's water quality, such as salinity, dissolved oxygen, temperature and other parameters, so as to promptly detect and control marine pollution.

5.Sewage treatment: used to monitor the water quality parameters of sewage, such as pH, COD, ammonia nitrogen, etc., in order to control and regulate the sewage treatment process.

6.Industrial production: used to monitor the water quality conditions in the industrial production process, such as pH, conductivity, dissolved oxygen and other parameters, so as to adjust the process process in a timely manner and ensure product quality.

7.Scientific research: used for water quality monitoring in the field of scientific research, such as lake eutrophication, climate change and other research.
