Introduction: Total phosphorus refers to the sum of orthophosphate, pyrophosphate, metaphosphate, polyphosphate and organic phosphate in water. The water sample is digested at high temperature and converted various forms of phosphorus into orthophosphate. The instrument adopts automatic control of water sample collection, high temperature digestion, reaction measurement, data processing and data transmission, and completes the whole process of analysis of total phosphorus in wastewater in rapid succession. According to the ammonium molybdate spectrophotometric method, the instrument uses potassium persulfate as a decomposing agent in an acid solution to convert polyphosphate and organic phosphorus into orthophosphate. The orthophosphate reacts with ammonium molybdate to form a yellow phosphomolybdenum antimony complex. The compound is reduced to phosphomolybdenum blue with ascorbic acid, and then its phosphate content is measured with a total phosphorus analyzer. Features: 1. 7-inch LCD touch screen is simple and convenient to operate, the interface is beautiful and generous, and the display content is rich and intuitive. 2. The integrated design of digestion and measurement makes the measurement results more accurate and fast. 3. The light source adopts imported monochromatic light diode, which has excellent performance, concentrated energy and low power consumption. 4. Using high-precision syringe pump, high measurement accuracy and low reagent consumption. 5. Adopt acid and alkali resistant, high temperature resistant valve circuit, long service life and less manual maintenance. 6. The instrument is equipped with a pretreatment device, which can meet different water quality measurement requirements. 7. With automatic calibration function, to ensure that the instrument can measure more accurately. 8. With intelligent maintenance function, automatic cleaning after each test to ensure that each measurement is more accurate and reduce the amount of manual maintenance.
