 Phosphate Analyzer is a design and manufacture of advanced photonics technology intelligent dedicated photometer detector, which applies to high water and ultrapure water and micro-quantitative determination of trace amounts of phosphate. The greatest feature of the instrument is zero at any time update, to ensure peak minus baseline measurement results are relative values, thereby enhancing the accuracy of measurement. The apparatus flow path and by the chemical circuitry of two parts. Circuit part of the use of advanced chip technology, highly integrated components, so failure rate to a minimum. Optical part of all imported components, to improve stability. Part of a unique flow path design, the optical path of about 12cm, if the concentration of water samples under the same, to improve the optical path can increase the resolution, the drainage valve is not used, the less well-known power components using failure rate is lower. This instrument uses high-grade aluminum chassis, dimensions 250mm × 250mm × 95mm, large format LCD display, reliable working hours of 50,000 hours or more, the whole Chinese menu, easy to use. Thin-film-style buttons, more than 50,000 life 
 The principle types of instruments based on photometric design. When the fixed wavelength of light passing through the measured water samples, the solute absorbs light, transmitted light intensity decreased. When the light source wavelength, the measurement optical path and other factors determined, the measured concentration and voltage as the inverse. 
 A standard solution for calibration of the color solution, the SCM system based on the concentration of standard solution and the corresponding voltage value, using the least squares method, fitting out a formula for calculating the concentration. 2-5 point calibration can be free. Is the thermal power plant in addition to salt water, steam, condensate, boiler water and chemical, pharmaceutical, chemical, semiconductor industry, high purity water and silicate determination of necessary test equipment. Advanced technology, unique design, allowing users to enjoy a new work ethic.
