Shenzhen Science Popularization Instrument K-YL2B portable residual chlorine analyzer (DPD)

1、 Product Introduction

Shenzhen Science Popularization Instrument K-YL2B portable residual chlorine analyzer,Suitable for detecting residual chlorine concentration in domestic or industrial water used by large, medium, and small water plants, industrial and mining enterprises, swimming pools, etc., in order to control the residual chlorine in the water to meet the water quality standards.

2、 Product 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.

3、 Technical indicators　　　　　　　　　　
1. Measurement range: 0-2.5-10mg/L
2. Power supply voltage: DC9V
3. Resolution: 0.001mg/L
4. Repeatability: ± 2%
5. Linear error: ≤ ±5％FS

4、 Product Features

1. Microcomputer, touch sensitive keyboard, clear LCD digital display, easy to use, comes with a portable waterproof tank with a waterproof rating of IP65.
2. The photoelectric colorimetric principle of spectrophotometry is adopted, which is convenient for the application of DPD reagents. After the water sample is put into the reagent for reaction, it can be read and the residual chlorine value can be displayed numerically.
3. Our company's patented 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, 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 immediately.

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, with non-linear processing and data smoothing functions. The minimum reading of the instrument is 0.001mg/L.

6. Integrating multiple independently designed patent achievements, advanced technology, and complying with the national standard GB/T5750-2006 for drinking water hygiene.
