Surface water conventional five-parameter portable water quality rapid tester

The synopsis of project
The ERUN-SP-M9000 series of surface water conventional five-parameter portable water quality rapid tester developed and produced by Erun Group is suitable for on-site rapid analysis of surface water environmental quality. The portable conventional five-parameter testing instrument for surface water refer to "GB 3838" standards, it can quickly detect five conventional water quality parameters: temperature, pH, dissolved oxygen, turbidity and conductivity of surface water such as rivers and lakes. The multi-parameter rapid water quality tester for rivers and lakes can be used for rapid testing of outdoor on-site surface water quality. It can help users quickly understand and grasp water quality conditions, and is of great significance for early warning of major or mobile water pollution incidents.
The contents of project

1、General 5 parameters of surface water:

(1) Temperature

Temperature fluctuations in surface water, especially non-seasonal abnormal changes, often have serious impacts on animals and plants in the ecological environment, and in extreme cases can lead to massive deaths. The GB 13195 thermometer method is mainly used for measurement.


(2)PH

The pH value of water quality is one of the key indicators. In surface waters, changes in pH affect animal feeding and algae's absorption of oxygen. The GB 6920 glass electrode method is usually used to measure pH value.


(3) Dissolved oxygen

Dissolved oxygen in water not only provides respiration for organisms, but is also used by oxygen-consuming microorganisms and is consumed by reducing substances such as sulfite ions, nitrite ions, and sulfides. It is the key to judging the self-purification ability of water quality, and is mainly measured by the GB 11913 electrochemical probe method.


(4) Turbidity

Turbidity reflects the cloudiness of water and is primarily caused by insoluble solids. Reducing turbidity helps reduce corrosives, bacteria, phytoplankton, and coliforms. The formazine turbidity method is currently widely used for determination.


(5) Conductivity

Conductivity not only shows the conductivity of water, but also indirectly reflects information such as total dissolved solids (TDS), salinity, and total ion concentration in the solution. The current mainstream measurement method is the electrode method.
