CODMN-2AZ (manganese method) COD analyzer for water plant

One Purpose:
Suitable for COD concentration detection in large, medium, and small water plants, in order to control the COD of water to meet the specified water quality standards.

II Principle:
This instrument applies the principle of microcomputer photoelectron colorimetric detection to replace the traditional visual colorimetric method. Eliminating human error, the measurement resolution is greatly improved.
III Technical indicators:
1. Measurement range: 0-6.0mg/L
2. Power supply voltage: DC9V
3. Resolution: 0.01mg/L
4. Repeatability: ± 2%
5. Linear error: ± (5% FS)

6. Dissolution time: 30 minutes

4 Characteristics:
1. Microcomputer, touch sensitive keyboard, clear LCD digital display, easy to use.
2. The photoelectric colorimetric principle of spectrophotometry is adopted, which is convenient for using reagents. After digestion, the water sample can be put into the reagent for reaction, and the COD value can be read numerically.
3. Our company's specially designed Zhuanli technology LED light source automatic control circuit ensures stable light source and solves the problem of preheating during startup. Its light source has a lifespan of up to 20 years and can be used directly without preheating when turned on.

4. The host is equipped with a high-power lithium battery and power adapter, suitable for quantitative measurement in the laboratory or field. It can be used continuously for 4 hours after charging for 4 hours, and is ready to use.

5. The instrument stores calibration curves within the full range, with power-off protection, and calibration data will not be lost. It can automatically zero and calibrate at 5 points. The data has non-linear processing and data smoothing functions. The instrument has a small reading of 0.01mg/L.

6. Integrating multiple independently designed achievements and technologies, in compliance with the national standard GB/T5750-2006 for drinking water hygiene.
