TGH-STN type total nitrogen water quality online automatic monitoring instrument

The TGH-STN type total nitrogen water quality online automatic monitoring instrument adopts the detection principle of high temperature and high pressure alkaline potassium persulfate digestion ultraviolet spectrophotometry. The pre treated water sample is digested under high temperature and high pressure conditions, acidified, and subjected to photometric detection to achieve rapid determination of total nitrogen concentration. The measurement method used by the instrument complies with the requirements of the "Water Quality Total Nitrogen Alkaline Potassium Persulfate Digestion UV spectrophotometry" standard (HJ636-2012).

Product features:

1. Select valve components: Choose reagent sampling timing, flexible and diverse channels, with advantages such as minimum volume, easy maintenance, and long service life.

2. Visual photoelectric system: Through the visual photoelectric system, precise measurement of reagents is achieved, overcoming quantitative errors caused by wear of peristaltic pump tubes.

3. Micro metering component: With precise quantification of trace reagents, it reduces the amount of reagents used.

4. Sample injection component: Peristaltic pump negative pressure suction, an air buffer zone is set between the reagent and the pump tube to avoid corrosion of the pump tube; At the same time, it makes the mixing of reagents more concise and flexible.

5. It has functions such as automatic range switching, automatic standard sample verification, and waste liquid separation.

6. Reagent tube: Imported modified PTFE transparent hose with a diameter greater than 1.5mm is used to reduce the probability of particle blockage in water samples.
