Description

Water quality detection equipment

Technical Field

The utility model belongs to the technical field of water quality detection, and particularly relates to water quality detection equipment.

Background

The oxidation-reduction potential parameter (ORP) is taken as an important index in water, and although the oxidation-reduction potential parameter (ORP) cannot independently reflect the water quality, the oxidation-reduction potential parameter (ORP) can be integrated with other water quality indexes to feed back the ecological environment in the water outlet system. The handheld water quality detector can be connected with an industrial ORP transmitter which is made of high-purity platinum, acid-resistant, alkali-resistant and oxidation-resistant, and is used for measuring ORP in the solution.

For the water body organisms, the proper PH value ranges from 7.5 to 8.5, and too low or too high is extremely unfavorable for the growth of the water body organisms, can cause the ecological balance to be broken, and the food chain in the water can also be broken. The pH value is too low, the aquatic organisms easily cause physiological hypoxia, the pH value is too high, the aquatic organisms are easy to erode gill part tissues, the gill part tissues are used as organs for filtering impurities and breathing of the aquatic organisms, and the aquatic organisms can only wait for death after being eroded.

Many organisms in water carry out photosynthesis, some carry out respiration, and the state of dissolved oxygen in a water body which is not polluted by organic matters is saturated, but when the content of the organic matters in the water exceeds the dissolved oxygen supplying speed, especially when the dissolved oxygen index is close to 0, the organic matters are easy to be decomposed in the environment, so that the water quality is polluted, and the index of harmful matters in the water is increased.

The conductivity of water refers to the degree to which water in a target body of water can conduct electricity. The conductivity in water is measured by the degree of penetration of electricity in water. If one wants to try to transfer electricity to pure water, this is not achieved, since pure water contains almost no ions that can conduct electricity. The presence of a large number of ions allows for greater water conductivity. However, there are a large number of conductive ions in the sea and water conductivity measurements are often used as an indicator to ensure that the sea and the living beings in the sea remain healthy. In addition to reflecting the health of seawater, it is also possible to work with the salinity of the body of water, which is measured in order to determine the content of dissolved salts in the water. Conductivity and salinity are often used in combination with each other because of the interactivity between them. Since conductivity is easily measured separately, these readings can be used to identify the total dissolved solids and salinity concentration in the water, both of which have an impact on water quality and aquatic life. Salinity is critical to water quality because salinity affects the solubility of dissolved oxygen.

From the above, the parameters such as ORP value, pH value, dissolved oxygen and water conductivity are important parameters for evaluating water quality, and the current water quality detection device is integrated with sensors capable of detecting different parameters, each sensor is protected by a protection cover to avoid bruising, and the protection cover also affects the water flow infiltration sensor, thereby affecting the detection result.
