【 Model recommendation: TH-SS07, a manufacturer of meteorological environment monitoring instruments and equipment. Yunjing Tianhe supports customized services for merchants. You can rest assured when choosing Shandong Yunjing Tianhe. 】 Portable water quality detector equipment - quickly arrive at the scene to quickly monitor multiple parameters of water bodies. The portable multi parameter water quality detector is a portable device that integrates multiple water quality parameter detection functions. It has the characteristics of portability, multi parameter detection, high accuracy and stability, intelligent operating system, diversified detection methods, data management and transmission, real-time positioning and on-site evidence collection, and is widely used in various fields such as environmental monitoring, drinking water safety, aquaculture, sewage treatment, etc. Designed with high-strength PVC engineering plastic carrying case, the structure is compact and easy to carry and operate. The overall weight of the machine is relatively light, usually around 10kg, making it convenient for users to carry out water quality testing work anytime and anywhere. Simultaneously detecting multiple key indicators of water bodies, such as pH value, dissolved oxygen, conductivity, turbidity, temperature, ammonia nitrogen, total phosphorus, total nitrogen, COD (chemical oxygen demand), BOD (biochemical oxygen demand), heavy metals (such as lead, mercury, cadmium, chromium, arsenic, etc.). High precision and stability are achieved through the use of high-precision sensors and imported light sources to ensure the accuracy of detection results. The precision rotating device detects the color tube, effectively ensuring accuracy and increasing stability by 10 times. Equipped with automatic calibration function, supporting single point or multi-point calibration, and customizable calibration cycle to ensure long-term stability.

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.
