application area
Widely used for wastewater testing in industries such as sewage treatment, chemical, pharmaceutical, hospital wastewater, food, printing and dyeing, and can also be applied to laboratory, emergency, and field monitoring and analysis.
Product Features
- The measurement method complies with the provisions of standard methods and has good consistency with manual analysis.
- Multi channel flow path design for batch testing of multiple samples simultaneously.
- Equipped with a large capacity lithium battery, it can be used for both AC and DC purposes and can be used for portable outdoor applications.
- Large capacity data storage and power-off protection design ensure that the instrument is not damaged and data records are not lost.
- Intelligent design for fault self diagnosis makes instrument management and maintenance simple and convenient.
- Measurement data can be exported using a USB flash drive for easy analysis and statistics by users.
- Low reagent usage, low operating costs, and strong anti-interference ability.
