Brief introduction: The instrument according to the latest standards of the state of the water quality of total nitrogen determination of the alkaline potassium persulfate digestion ultraviolet spectrophotometry (HJ - 2012 instead of 636 GB 11894-89), "design and manufacturing, is specially according to the situation of water quality in our country and national regulations and rapid development of a total nitrogen tester, this instrument is stable performance showed clear, measure the rapid, simple and convenient use, can be widely used in environmental protection, scientific research, production monitoring and other fields, is an ideal instrument to environmental monitoring and control. Features: 1. Rapid and accurate determination of surface water, groundwater, water, urban sewage and industrial waste water, total nitrogen content in concentration direct reading; 2 gb uv method, dual wavelength detection process automatically switches and automatically calculate total nitrogen, measurement accuracy; 3. The sample room is square pool, and is suitable for a variety of specifications than the color of plating, to ensure that the measuring precision and can support more extension project; 4. Can store the testing data in real time, storage capacity of up to 50000 groups (including test date, test items, test results); 5. The instrument memory work curve can be directly call and concentration of automatic calculation results, while 180 extension curve with space, convenient user establish extended range and expand the test items 6. Have automatic multipoint linear fitting function, user extension project can be directly call curve fitting procedures, no manual calculation curve; 7. Choose 7 inch high reliability, good stability, strong full color LCD touch screen, clear display measurement project, comprehensive information on the absorbance value, density and the man-machine interactive operation, to provide customers the most friendly and convenient operation experience; 8. Instrument built-in high-end brand micro thermal line printer, can print test results fast, convenient data retained; 9. Support on-line detection data processing, the current data and historical data storage can be uploaded to the computer for processing through the cable. Technical indicators: Measuring range: 0-80 mg/L (section measurement) Detection limit: 0.2 mg/L Measurement error: plus or minus 10% or less Repeatability error: plus or minus 3% or less Photometric drift: 0.005 A/h or less The sample room, multi-function color pool Storage: to test 50000 groups of data The number of curve: more than 180 Presentation: 7 inches full color LCD touch screen Operation mode: touch screen man-machine interactive operation Print mode: thermal line printing : standard RS232 communication interface Power supply: 220 v
