amonia nitrogen analyzer detector

AD-82B laboratory handheld portable desktop ammonia nitrogen detector reagent analyzer analyzer product description: The ammonia nitrogen analyzer is suitable for the detection of ammonia nitrogen concentration in large, medium and small water plants, industrial and mining enterprises, and domestic industrial water, so as to control the ammonia nitrogen of the water to meet the prescribed water quality standards. Product principle: This instrument uses microcomputer photoelectron colorimetric detection to replace the traditional visual colorimetric method. Elimination of human error, so the measurement resolution is greatly improved. Features: 1. Microcomputer, touch keyboard, LCD liquid crystal display numbers clearly, easy to use 2. Using spectrophotometric photoelectric colorimetric, it is convenient to use reagents. The water sample can be counted within a few minutes after the reagent is reacted. The number shows the value of ammonia nitrogen. The reagent is packaged in a convenient water bottle. 3. The patented LED light source automatic control circuit made by our company has stable light source and solves the problem of preheating when starting up. The light source has a lifespan of up to 20 years, and it can be used directly without preheating. 4. The high-power lithium battery and power adapter in the main unit are suitable for quantitative measurement of the soup in the laboratory. It can be used continuously for 4 hours after charging for 2 hours, and it is ready to use. 5. The instrument stores the calibration curve within the full range, and the power failure protection is provided. The calibration data will not be lost. It can be automatically adjusted to zero and 5 points. The data has non-linear processing and data smoothing functions. The minimum reading of the meter is 0.01mg /L. technical parameter: 1. Measurement range: 0.02~25mg/L; 2. Minimum indication value: 0.01mg/L; 3. Repeatability: ≤1%; 4. Accuracy: ±5%FS±1 word;
