TGH-STP b-type total lead water quality online automatic monitoring instrument

The TGH-STP b-type total lead water quality online automatic monitoring instrument adopts the xylenol orange spectrophotometric method. In a buffer liquid system, lead reacts with xylenol orange to form a light red complex, and the absorbance of the solution after the reaction is measured. The measurement method used by the instrument complies with the requirements of the GB/T7470 water quality - Determination of lead - spectrophotometric method (HJ762-2015) standard.

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.
