Date: 2025-12-23Read: 12
Model recommendation:TH-SS07As a manufacturer of meteorological and environmental monitoring instruments and equipment, Yunjing Tianhe supports customized services for merchants. You can rest assured that the sewage quality detector is a precision instrument specifically designed to evaluate the quality of sewage. It is equipped with various professional sensors that can quickly and accurately detect key indicators such as chemical oxygen demand (COD), biochemical oxygen demand (BOD), ammonia nitrogen, total phosphorus, total nitrogen, pH value, suspended solids, etc. in sewage, comprehensively reflecting the degree of sewage pollution. The instrument is easy to operate, with some models supporting one click detection, real-time data display, and the ability to store and transmit data for easy subsequent analysis. It has strong anti-interference ability and is suitable for different scenarios such as industrial wastewater and domestic sewage. With its help, it is possible to timely grasp changes in sewage quality, providing scientific basis for adjusting sewage treatment processes and meeting discharge standards.
1、 Product Introduction
The SS07 portable multi parameter water quality analyzer is an electrode based water quality analysis instrument that uses fully digital electrodes to detect water quality, water temperature, conductivity, and other parameters PH、 Ammonia nitrogen, dissolved oxygen cod、 Turbidity parameter. The instrument is equipped with a self-developed FTIOT operating system, which is easy to operate, stable in performance, accurate in measurement, and has a wide detection range. It is also equipped with a high-capacity rechargeable lithium battery, making it convenient for users to conduct water quality testing in the field or laboratory at any time.
