Water Quality Detector Ammonia Nitrogen Concentration Analyzer 0.02-25mg/L

Water Quality Detector Ammonia Nitrogen Concentration Analyzer 0.02-25mg/L Ammonia nitrogen (NH3-N) in the presence of free ammonia (NH3) or ammonium salt (NH4+) in water, the composition ratio depends on the pH value of water. When the pH value is high, the ratio of free ammonia is higher. Conversely, the ratio of ammonium is high. The main source of ammonia nitrogen in water is the decomposition product of organic matter in wastewater containing organic matter, and some industrial wastewater, such as coking wastewater and synthetic ammonia fertilizer plant wastewater. In addition, in the anaerobic environment, nitrite in water can also be affected by microorganisms, reduced to ammonia. In aerobic environment, ammonia in water can also be converted to nitrite, or even to nitrate. Determination of nitrogen compounds in various forms, contribute to the evaluation of water pollution and the status of &rdquo “ purification. When ammonia nitrogen content is high, it can be toxic to fish. Two, working principle The instrument adopts the method of measuring the ammonia nitrogen in water by the method of Na’s colorimetry. The method has the advantages of simple operation and high sensitivity. Its principle is: the free ammonia or ammonium ions in the form of ammonia nitrogen and sodium reagent reaction to produce yellow brown complex, the chroma of the complex is proportional to the content of ammonia nitrogen. Three, product features and technical parameters: Product features: 1, the use of cold light, monochromatic light as the light source, the optical stability is excellent, not disturbed by various light. 2, large screen LCD display. 3, can store 20 historical records, no loss of power. 4, with the factoryInternal pre storage Curve recovery function. 5, the host chassis using molded ABS material, good corrosion resistance. Technical parameter: 1, measurement range: 0.02-25mg/L (ultra range can be determined after dilution) 2, indication error: ± 3% (F.S) 3, repeatability: ≤ 3% 4,Optical stability: the absorption value of the instrument is less than 0.002A in 20min 5,Dimensions: 266× 200× 130 (mm) 6,Weight: 1KG 7,Power consumption: < 10W 8, the normal use of conditions: The environment temperature: 5 ~ 40 degrees The relative humidity: 85% ≤ The power supply: 1.5V battery The free vibration and electromagnetic interference significantly, avoid direct sunlight.

Ammonia Nitrogen Analyzer Detector Portable Water Quality Monitor 0.02 to 25mg/L

Ammonia (NH3-N) to free ammonia (NH3) or ammonium (NH4+) form exists in the water, the composition ratio depends on the pH of the water. On the contrary, the proportion of ammonium salt as high. Its principle is: to free ammonia or ammonium ions form of ammonia nitrogen and na’s reagent reaction generated yellow brown complex, the complex of chromaticity is proportional to the content of ammonia nitrogen.
