III 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 the application of reagents. After the water sample is placed in the reagent for reaction, it can be read within a few minutes, and the digital display shows the value of dissolved oxygen. The reagent is packaged in a convenient drip bottle.
3. Our company's specially designed 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 can be equipped with a high-power battery, which can be used for quantitative measurement in the field. It can be used continuously for 4 hours after 2 hours of charging, 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. Integrate multiple independently designed achievements and technologies, in compliance with the national standard GB/T5750-2006 for drinking water hygiene.
