Brief introduction of multiparameters
In order to protect the water environment, it is necessary to strengthen the monitoring of sewage discharge. The quality of the design and inspection of the test points (mainly multi-parameter water quality analyzers) plays a vital role in water environmental monitoring. Determination of various chemical components in water by chemical and physical methods. Multi-parameter water quality analyzer is divided into simple analysis, full analysis and special analysis of three. Brief analysis in the field, the analysis of the project less, but requires fast and timely, apply to the initial understanding of a large area within the aquifers of the main chemical composition of groundwater specific analysis of the project according to the specific needs of the task. Another multi-parameter water quality analyzer can quickly and accurately qualitative and quantitative analysis, and can be fully automated, intelligent, real-time online, multi-parameter analysis at the same time, the results and print the report card.
Features of NANBEI multiparameters:
1. It can measure pX/pH, ORP, conductivity, TDS, salinity, Resistivity, dissolved oxygen, saturation and temperature.
2. It adopts LCD display and Chinese operation interface.
3. It has manual/automatic temperature compensation.
4. It provides zero oxygen and full scale calibration.
5. When the meter measures conductivity, it can switch frequency automatically to guarantee measuring accuracy.
6. It has power failure protection functions.
