The working principle of general device to test water quality is to involve the corresponding substances in water by electrochemical reaction or chemical reagent reaction, and then calculate the content of the corresponding substances in water by colorimetry, titration and conductivity measurement. In order to protect the water environment in production and life, it is necessary to strengthen the monitoring of sewage discharge. The quality of drinking water is declining, which is harmful to human health. Water quality measurement devices play an important role in environmental protection, water quality detection and water resources protection.
Device to test water quality is divided into multi-parameter measuring instrument and single-parameter measuring instrument according to their functions.
Devices to test water quality are divided into COD, BOD, ammonia nitrogen, total phosphorus, turbidity and PH meters.
Device to test water quality can be divided into portable measuring instrument, Laboratory Intelligent Measuring instrument, simple economic measuring instrument, online measuring instrument and so on.
