The water quality monitor is a professional instrument and equipment used for the monitoring of water quality environmental parameters. The accurate detection system of the water quality monitor can help users obtain fine data, analyze the water body conditions more accurately and effectively, prevent breeding risks in advance, and avoid losses in time. The water quality monitor senses the changes in the water quality environment, and the water quality sensor needs to be mainly relied on to collect the water quality environment. So what sensors are commonly used in water quality monitors? No.1 Residual Chlorine Sensor Chlorine is the most widely used disinfectant, especially in the disinfection process of drinking water. The residual chlorine sensor can detect the content of free chlorine, monochloramine and total chlorine in water samples. No.2 TOC sensor TOC is also called total organic carbon. It is an important target for analyzing the pollution of organic matter in water samples, and TOC sensors are also mostly used in water quality analysis in the pharmaceutical industry. No.3 pH sensor The pH sensor first obtains the acid-base value of the water body by detecting hydrogen ions, and the pH value is an important goal of the water body, and there are strict requirements for the water body pH value in many occupations. No.4 Conductivity sensor The conductivity sensor can be said to be the most used sensing device in the water quality detector. It is mainly used to detect the concentration of total ions in the water body, and can be divided into electrode type, inductive type and according to different measurement principles. Ultrasonic type. No.5 ORP sensor ORP sensor is mainly used for the oxygen recovery potential of the solution. It can not only detect the water body, but also detect the ORP data in the soil and culture medium. Therefore, it is also the sensor with the most application fields. Usually it Will be used with PH sensor. No.6 Turbidity Sensor The turbidity sensor measures the suspended solids in the water by measuring the amount of light passing through the water, and these suspended solids can reflect the pollution of the water body. Therefore, it is often used in the measurement of rivers, sewage and wastewater by water quality detectors. No.7 Dissolved oxygen sensor is a sensing device that measures the amount of oxygen dissolved in water. The oxygen molecules in the solution to be measured penetrate the selective membrane of the sensor, and the corresponding reduction or oxidation reaction occurs on the cathode and anode inside the sensor, and at the same time A current signal is generated, and the magnitude of the current is proportional to the concentration of dissolved oxygen, and the concentration of dissolved oxygen is judged by the magnitude of the current.
