Product Introduction
The ESN2000 multi-parameter water quality on-line analyzer is a device used for real-time monitoring of multiple key parameters in water bodies. It provides continuous and accurate data, helping users to promptly understand the water quality situation and take corresponding measures. It is applied in fields such as environmental monitoring, water resources management, and health supervision.
Measured Parameters
It can measure one or multiple parameters, and up to 6 parameters can be measured simultaneously.
Temperature Chlorine Dioxide/Residual Chlorine/Ozone pH Turbidity Conductivity Oxidation-Reduction Potential
Instrument Features
- Modular design, easy to maintain;
- It can monitor and display 6 parameters simultaneously;
- Fast response time, capable of quickly and accurately monitoring the changes of water samples;
- For residual chlorine measurement, the three-electrode constant potential method is used, and only the reference electrode needs to be replaced, reducing the cost of consumables;
- It can measure residual chlorine/chlorine dioxide/ozone, and can be directly switched through the menu;
- No reagents are required, and there is no secondary pollution;
- Closed pressure flow path, not easy to scale, with automatic sewage discharge, requiring little maintenance for a long time;
- Built-in flow compensation, not affected by flow rate and pressure, providing more accurate measurement;
- Built-in Internet of Things module (optional), and the data can be accessed to the user platform;
- Support for real-time viewing of instrument monitoring data through the mobile APP;
- Design in a modular way, and the protocol can be customized according to user requirements;
- Built-in water shortage detection system, which can feedback the operation status in real time, improving the reliability of monitoring data;
- Users can remotely control the instrument through the platform and mobile APP, reducing the cost of manual operation and maintenance;
- Support for chemical dosing control, realizing intelligent dosing.
