USES: YL-1AZ portable residual chlorine detector is applicable to the detection of residual chlorine concentration of domestic or industrial water in large, medium and small water plants, industrial and mining enterprises, swimming pools and other places, so as to control the residual chlorine of water to meet the specified water quality standards. Principle: This instrument USES microcomputer photoelectron colorimetry detection principle to replace the traditional visual colorimetry. The human error is eliminated, so the measurement resolution is greatly improved. Technical indicators: 1. Measurement range: 0-2.5mg/L 2. Power supply voltage: DC9V 3. Resolution: 0.01mg/L 4. Repeatability: plus or minus 1% 5. Linear error: + / - (5% FS+1 word) Features: 1. Microcomputer, light touch keyboard, LCD digital display, easy to use. 2. The photoelectric colorimetry principle of spectrophotometry is adopted to apply the convenient reagent. After the water sample is put into the reagent for reaction, it can be read for more than ten seconds and the value of residual chlorine can be displayed numerically. 3. The company's special patent technology LED light source automatic control circuit, the light source is stable, to solve the startup must preheat. Its light source life is as long as 20 years, when the boot without preheating, can be used directly. 4. The host is equipped with high-power lithium battery and power adapter, which is suitable for quantitative measurement in laboratory or field. It can be used continuously for 4 hours after charging. 5. The calibration curve within the full range is stored in the instrument, with power failure protection, and the calibration data will not be lost. Automatic zero adjustment and 5 point automatic correction, non-linear data processing and data smoothing function, the minimum reading of the meter is 0.001mg/L. 6. Integrated with a number of independent design patent results, advanced technology, in line with the national standard GB/ t5750-2006 domestic and drinking water hygiene standards.
