Full spectrum water quality rapid analyzerBased on UV visible absorption spectroscopy technology, multi parameter synchronous analysis is achieved through full band scanning. Its advantages are reflected in multiple aspects such as detection efficiency, accuracy, environmental friendliness, intelligence, and cost-effectiveness, as follows:
1. Multi parameter synchronous detection significantly improves efficiency
Wide coverage: It can simultaneously measure more than 20 water quality parameters such as COD (chemical oxygen demand), ammonia nitrogen, total phosphorus, total nitrogen, nitrate, turbidity, chromaticity, chlorophyll-a, TOC (total organic carbon), etc., meeting the detection requirements of most indicators in the "Environmental Quality Standards for Surface Water" (GB 3838-2002).
Single detection replaces multiple operations: Traditional methods require step-by-step use of different instruments or reagents to detect various parameters, while a full spectrometer can complete multiple analyses with one scan, reducing time by more than 80% (such as from 2 hours to 10 minutes).
2. Quickly respond and adapt to on-site emergency needs
Extremely fast detection speed: Most models can complete detection within 60 seconds, while some models (such as Quick90) have a response time of ≤ 10 seconds, much faster than traditional spectrophotometry (which takes 15-30 minutes).
Real time monitoring capability: suitable for rapid screening of sudden pollution events (such as chemical spills, algal outbreaks), providing data support for emergency decision-making.
3. High precision and stability, reliable data
Dual beam compensation technology: By comparing the reference beam with the sample beam, real-time elimination of the influence of light source fluctuations and environmental interference (such as temperature changes) on the results is achieved, with a transmittance accuracy of ≤ 0.3% T and a wavelength error of ≤ 0.5nm.
Advantages of full band scanning: Covering the entire 190-750nm band, it can capture more characteristic absorption peaks and avoid errors caused by overlapping interfering substances in single wavelength detection. For example, when detecting COD in high chlorine wastewater, traditional methods may produce bias due to chloride ion interference, while full spectrometers can correct the results through multi wavelength fitting.
Compliant with national standards: The test results meet the requirements of standards such as HJ/T 399-2007 (COD rapid method) and HJ 535-2009 (ammonia nitrogen Nessler's reagent spectrophotometric method), with an error range of ≤± 5% FS.
4. No need for chemical reagents, environmentally friendly and safe
Zero reagent consumption: Based on optical principles, there is no need to add heavy metal salts, strong acids, or other reagents to avoid secondary pollution (such as traditional COD detection that requires the use of mercury sulfate to mask chloride ions, resulting in mercury containing waste liquid).
Operational safety: reduces the risk of exposure to toxic and harmful reagents, especially suitable for long-term use by laboratory personnel or on-site testing personnel.
Low operating costs: No need for reagent procurement, storage, or waste liquid treatment fees, long-term use can save more than 50% of costs.
5. Intelligence and portability, adaptable to diverse scenarios
Intelligent operating system: equipped with a 7-inch color touch screen, supporting Chinese menu, one click detection, automatic calibration, data storage (can store more than 1000 sets of data), and USB flash drive export.
Internet of Things Integration: Supports RS485 signal output, 4G/Wi Fi modules, and can be integrated with environmental monitoring platforms or enterprise ERP systems to achieve remote monitoring and data sharing.
Portable design: Some models (such as T6800) weigh ≤ 5kg and are equipped with a portable case, suitable for outdoor, vehicle mounted, or mobile laboratory use.
6. Modular expansion to meet customized needs
Flexible configuration of detection items: Users can choose basic modules (such as COD+ammonia nitrogen) or extended modules (such as heavy metals and pesticide residues) according to their needs to avoid functional redundancy.
Easy software upgrade: The host software can be updated through a USB flash drive or online, supporting the addition of new parameters or algorithm optimization to extend the device's lifespan.
7. Wide applicability, covering the needs of the entire industry
Environmental monitoring: detection of surface water, groundwater, inflow and outflow of sewage treatment plants, and industrial wastewater.
Drinking water safety: Water treatment plants, secondary water supply, bottled water, mineral water testing.
Industrial production: monitoring of wastewater discharge in industries such as chemical, pharmaceutical, food, and papermaking.
Research and teaching: Environmental engineering, food science and other majors in universities are used for experimental teaching of water quality analysis.
