The GA-HB04 environmental four parameter water quality detector can quickly and accurately measure indicators such as CODcr, ammonia nitrogen, total phosphorus, and total nitrogen in surface water, groundwater, urban sewage, and industrial wastewater, with direct concentration reading; It can be widely used in sectors such as water plants, food, chemical, metallurgical, environmental protection, and pharmaceutical industries. The environmental four parameter water quality detector is a combination of a single fixed wavelength and fixed purpose spectrophotometer. It uses the principle of spectrophotometry to measure various parameters and establishes a linear curve between the concentration color rendering degree and absorbance of different parameters in the instrument. The instrument determines the concentration of the tested water sample by identifying the color. This instrument adopts a fully Chinese menu, which is easy to operate, convenient to use, and has high measurement accuracy.

The environmental four parameter water quality detector integrates CODcr rapid analyzer, ammonia nitrogen analyzer, total phosphorus analyzer, etc., and can quickly and accurately determine the concentration of relevant parameters in various types of water bodies.

The environmentally friendly four parameter host adopts a streamlined appearance design, and the surface material has been specially treated to have characteristics such as oxidation resistance, acid and alkali resistance. The body is made of polymer engineering materials, which are integrated into a lightweight and beautiful design.

During instrument testing, a 16mm colorimetric tube is used to complete the digestion and detection of the water sample in one unit, without the need to switch the water sample to a colorimetric dish again. This reduces the number of operational steps and avoids interference from other substances during the pipetting process, thereby reducing the probability of errors in the detection results.
