UPW-Q700CN fully automatic COD ammonia nitrogen analyzer Introduction: COD ammonia nitrogen analyzer is widely used in various industries and departments that require COD and ammonia nitrogen content analysis in water, such as environmental protection, water conservancy, agriculture, chemical industry, health and epidemic prevention, tap water, aquaculture, marine investigation, sewage treatment, production water quality control, etc. It can be applied to fixed laboratories or mobile monitoring vehicles. Testing basis: HJ/T 399-2007 Determination of Chemical Oxygen Demand in Water Quality - Rapid Digestion Spectrometric Method HJ 535-2009 Determination of Ammonia Nitrogen in Water Quality - Nessler's Reagent spectrophotometric method Features: 1. Developed and improved based on current national environmental standards, using standardized consumables regardless of sample concentration, allowing users to directly measure unknown water sample concentrations and avoid multiple operations 2. Equipped with functions such as one click detection and one click cleaning, the entire process of liquid intake, quantification, digestion, cooling, detection, waste disposal, and cleaning is fully automated, without the need for contact with chemical reagents. It is safe and reliable, and can also be used by non chemical personnel 3. COD adopts dual optical path high-precision detectors of 420nm and 610nm, while ensuring the detection accuracy of high and low concentration samples 4. Equipped with sample testing programming function, users can choose to test a single indicator or test two indicators in sequence, which is flexible and convenient to use 5. Equipped with specialized reagents and consumables to effectively ensure the accuracy of detection data. With preset standard curves, users can perform testing without configuring standard solutions, greatly reducing testing time and saving costs 6. Adopting a 7-inch high-resolution true color touch screen, the user-friendly and concise menu design makes operation more time-saving. A single interface contains detailed information such as detection time, items, absorbance, transmittance, concentration values, curves, etc 7. The digestion device is powered by safe voltage, and the whole machine does not require high voltage, which is safe and reliable 8. The digestion device is equipped with a fast air cooling device to improve the detection speed and ensure the stability and accuracy of the detection results 9. Adopting a long-life cold light source and solid-state detector, the instrument performs control system self-test, detector self-test, and energy calibration every time it is turned on to ensure system reliability and data accuracy 10. The instrument is equipped with 100 standard curve storage locations, supporting automatic curve calibration, automatic saving of calibration curves, and supporting users to establish extended detection projects. User curve data and self built project information can be saved in case of power failure 11. The instrument comes with a dedicated embedded printer, which integrates sample detection and data printing, and can print real-time and historical data anytime and anywhere 12. Equipped with a dedicated communication interface, data can be summarized and statistically analyzed through upper computer software 13. With a large storage capacity, it can store 10000 sets of detailed detection data, making it easy for users to view, count, or print in the future 14. Adopting micro detection technology, the consumption of a single detection sample is one milligram upgrade 15. Imported components are used for key pipelines, with reserved maintenance ports, making it convenient for customers to replace aging pipelines on their own 16. It has the function of automatically creating regression curves, allowing users to directly expand new detection items without manual calculation. It supports 5-point fitting, and the fitted curve can be saved for a long time for easy future reference 17. Can be equipped with UPS power supply 18. It can be equipped with a fully automatic sampler to achieve automatic measurement of multiple samples and has the function of automatic sample dilution Parameter indicators: Light source lifespan: 100000 hours Optical stability: ± 0.003Abs/10min Absorption range: 0.000-3.000 Abs Resolution: 0.001Abs Temperature control range: Room temperature~190 ℃ Number of curves: 100 Storage data: 10000 sets Display mode: 7-inch true color touch screen Parameter switching: Touch based automatic switching Communication interface: RS232/USB Printing method: Embedded printer Measurement range: COD 0-1000mg/L, ammonia nitrogen 0-10.0mg/L Measurement accuracy: ≤± 5%
