Application:

Used for online continuous monitoring of phosphate content in boiler water of steam power plants

Main features:

1. Using patented technology - a constant pressure controllable timing injection device, as a quantitative solution for water samples and reagents in the instrument; Abandon peristaltic pumps, capillaries, and air pressureQuantitative scheme for precision metering pumps. Greatly simplifying the quantitative system, reducing maintenance costs, and improving reliability.
2. Using patented technology, a composite photoelectric detection device has been developed, which includes a mixer, reactor, stirrer, colorimetric cup, and photoelectric colorimeter in chemical reactionsInternalization simplifies the structure and minimizes maintenance.
3. Periodic measurement and automatic cleaning methods eliminate bubble interference, accumulated pollution, sample crossover, and measurement lag that are difficult to solve with traditional technical solutionsStubborn illness greatly improves the stability of the instrument.
4. Use only one reagent.
5. Extremely low operating costs, with an annual cost of approximately 750 RMB per unit.
6. Complies with the DL/T677-2009 standard for the power industry of the People's Republic of China.
