4、 Characteristics:
1. Microcomputer, touch sensitive keyboard, clear display of LCD numbers, 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 put into the reagent for reaction, it can be read within a few minutes, and the numerical display shows the value of chromium. The reagent is packaged in a convenient drip bottle.
3. Our company's 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 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 be automatically zeroed and calibrated at 5 points. The data has non-linear processing and data smoothing functions. The minimum reading of the instrument zu (i) is 0.001mg/L.
6. Integrating multiple independently designed achievements, advanced technology, and complying with the national standard GB/T5750-2006 for drinking water hygiene.
