2、 Sensor Introduction
1. Dissolved oxygen sensor - conventional five parameter water quality monitoring instrument
Unlike ordinary DO electrodes, the polarographic thin film electrode uses a constant potential three pole testing system. The unique testing principle enhances the accuracy and reliability of electrode testing, and has a complete self diagnostic function.

2. pH/ORP Sensor - Conventional Five Parameter Water Quality Monitor
The online continuous monitoring of pH in the sewage treatment process imposes very strict requirements on instruments and sensors. A reliable operating system must meet the following requirements: the structure must be sturdy and durable, and the testing must be stable, safe, and reliable.
A complete set of sensors has been developed for online monitoring of sewage treatment in harsh environments, including an immersion type sturdy sheath with a preamplifier and glass sensing electrodes.

3. Conductivity Sensor - Conventional Five Parameter Water Quality Monitor
Strong anti-interference ability, stable and reliable operation

4. Turbidity Sensor - Conventional Five Parameter Water Quality Monitor
The online turbidity test adopts the scattered light turbidity method, which complies with the EN ISO 7027 standard. The characteristic of an online turbidity meter is that its testing range is very wide, with a turbidity of 0-5000NNU.
5. Turbidity testing principle
Turbidity is caused by suspended particles in water, which reflect incident light. Usually, scattered light in the 90 degree direction is used as the test signal, and the unit measured in this way is called NTU. The unit measured by the instrument calibrated with Formazine standard solution is called FNU. This method is suitable for testing low to medium ranges, from 0.01 to 5000 FNU. Using 860nm infrared light as the light source, it is not affected by the chromaticity of the sample.

Using precision optical components, the optical lens is made of wear-resistant sapphire;
Integrated design ensures reliable operation and undergoes strict and accurate calibration before leaving the factory.

3、 Application Fields

Suitable for online automatic monitoring of water quality for drinking water, surface water, etc.
