DS-300A three-in-one COD, ammonia nitrogen, and total phosphorus analyzer

Type D, ammonia nitrogen, total phosphorus three-in-one meter
Product description
1. Instrument description:
This product combines the classic colorimetric method with advanced computer technology The application of microcomputer photoelectronic colorimetric detection principle to replace the traditional visual colorimetric method eliminates human errors and greatly improves the measurement resolution. The automation of the measurement process is realized. It can be widely used in sewage outlet monitoring of factories and mines, import and export monitoring of urban sewage treatment plants, water quality monitoring of rivers and lakes, and process control of sewage treatment facilities.
2. Main functional features:
● Large-screen LCD backlight display, pure Chinese operation interface and humanized programming.
● It has a wide measuring range and can automatically switch the measuring range according to the actual situation of the water sample.
● Point-to-point correction mode automatically calculates slope, intercept and correlation coefficient with high measurement accuracy.
● The intelligent design of fault self-diagnosis makes instrument management and maintenance simple and convenient.
● Large-capacity data storage power-off protection design ensures that the instrument is not damaged and data records are never lost.
● Strong anti-interference ability and suitable for industrial sites.
● Can be widely used in monitoring surface water and pollution sources.
● Using a unique semiconductor cold light source, the light source life span can reach tens of thousands of hours.
● Can be connected to a computer to export measurement data and can be connected to a printer to automatically print measurement data.
● Less reagent consumption, lower running costs and strong anti-interference ability.
