YL-1AZ portable residual chlorine detector

one. Purpose:

YL-1AZThe portable residual chlorine detector is suitable for detecting the residual chlorine concentration of domestic or industrial water in large, medium, and small water plants, industrial and mining enterprises, swimming pools, and other places, in order to control the residual chlorine in water to achieve the specified water quality.

two. 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.

three.Technical indicators:

1.Measurement range:0-10mg/L

2.Power supply voltage:220V/50Hz/DC7.5V/0.2ADirect current1.5V×5Save battery

3.resolving power:0.01mg/L

4.Repeatability:1%

5.Linear error: ±（5％FS+1One word)

6. Can store 10 sets of experimental data for easy viewing after the experiment is completed

four.characteristic:

1.Microcomputer, touch sensitive keyboard,LCDThe LCD displays clear numbers, can automatically shut down, and is 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 residual chlorine value is displayed digitally.

3.Our company's technologyLEDThe light source automatic control circuit ensures stable light source and solves the problem of preheating during startup. Its light source has a long lifespan20Year, no preheating is required when starting up, it can be used directly.

4.The instrument stores calibration curves within the full range, with power-off protection, and calibration data will not be lost. Automatic zeroing and5Automatic point correction, data with non-linear processing and data smoothing functions, instrument zu (i) small reading is0.01mg/L.

5.Integrating multiple independently designed achievements, advanced technology, in compliance with national standardsGB/T5750-2006The hygiene of drinking water is poor.
