Instrument characteristics
1.& nbsp; The analyzer is separated from the digester and does not affect the stability of the optical system.
2.& The instrument is a cold light source, narrow-band interference optical system, good optical stability, 16 adjustable light intensity during calibration, arbitrary setting, can effectively solve the problem of measurement range expansion caused by signal strength.
3.& nbsp; Host and resolution instrument color touch screen, Chinese and English display, friendly operation interface, with operation guide help, to explain various functions.
4.& nbsp; You can query the curve. In addition to querying the curve equation, you can also query the standard value and corresponding absorbance of each standard substance during calibration, as well as the calibration time and calibration personnel number, and completely reproduce the state during calibration.
5.& nbsp; With one-button restore function, when the factory curve and user curve data records are lost due to accidents, one-button restore can be realized.
6.& nbsp; The resolver has a multi-point error-free calibration to achieve zero-error measurement of the set point, completely eliminating the error caused by the nonlinearity of the common resolver on the market due to temperature sensors.
7.& nbsp; The digestion instrument has a regular reminder and can be set to automatically shut down after digestion. The instrument has a secondary protection function. When the temperature of the digestion instrument exceeds 200 degrees, the instrument will cut off the power supply itself to ensure the safety of the digestion process.
8.& nbsp; In addition to the factory curve * more than 250 curves, the user can add 3500 curves by himself, calibrate the curve, and store it in the instrument.
9.& Up to 100,000 records are stored (including parameter name, concentration, unit, detection time, operator number, etc.).
10.& Print function: you can print the test records immediately or query the records.
11.& nbsp; USB port, can connect to a computer.

Shenzhen Changhong Technology Co., Ltd. is a high-tech enterprise founded in 2002. For more than 20 years, we have been committed to the research and development, production and sales of hundreds of water quality monitoring instruments such as COD determinators, ammonia nitrogen determinators, total phosphorus determinators, total nitrogen determinators, and various water quality heavy metals and inorganic compounds. Product technology involves computer, MCU software and hardware, optics, chemical analysis and other technical fields. The company's current products mainly include: COD tester, ammonia nitrogen tester, total phosphorus tester, total nitrogen tester, turbidimeter, residual chlorine tester, copper, iron, nickel, zinc, hexavalent chromium, nitrite, cyanide, sulfide, iodide, volatile phenol, hydrazine, aniline and other monitoring instruments for hundreds of substances in water. At the same time, it produces instruments for measuring physical parameters in water such as pH, conductivity, dissolved oxygen, turbidity, chroma, and total hardness. The company's products have been sold all over the country. Currently, there are more than 8,000 domestic customers, located in more than 20 provinces, municipalities and autonomous regions across the country, and exported to Thailand, Indonesia, Singapore, Europe and the United States and other countries. It has formed a good reputation among users and has become the leader in the domestic water quality testing instrument industry with the most complete varieties, the most stable product quality, and the best comprehensive performance indicators. The "Shenchanghong" brand has also become a well-known brand in my country that independently produces water quality testing instruments. The company has been focusing on product quality management and new product research and development for many years, and the stability, repeatability and operability of its main products are in a leading position in China. The comprehensive performance is close to or even partially beyond the most well-known foreign brands, and more than 8 newly developed products are released every year. Product sales steadily occupy the market at an annual growth rate of more than 30%. Changhong Technology is becoming a well-known enterprise in China's water quality testing instrument industry in a way of "active innovation, quality priority, continuous progress, and steady advancement".
