Product Introduction
The instrument can quickly determine COD, ammonia nitrogen, total phosphorus, total nitrogen, turbidity, suspended solids, etc. in various water quality, and integrates mature technology in the field of water quality analysis, making the entire analysis system more perfect, simpler and faster operation, and more stable and reliable detection results. It is widely used in emergency monitoring, industrial wastewater, domestic sewage, sewage treatment, chemical industry, food, beverage, textile printing and dyeing, electroplating, papermaking, petroleum metallurgy, river management, scientific research units, colleges and universities and other fields.
Principle of operation:
The digestion colorimetric integrated tube and the multi-channel water quality rapid Tester can be used seamlessly, and are compatible with φ25mm colorimetric tubes.
● The testing of each parameter is in line with national standards, industry standards or international standards.
● Two built-in COD detection methods
Method 1: HJ/T399-2007 (National Standard)
Method 2: Import testing method
● The standard detection parameters are as follows:
- COD (Prefabricated Reagents)
- COD (Powder Pack Reagent or Custom Reagent)
- Ammonia nitrogen (NH3-N)
- Total Phosphorus (TP)
- Turbidity - Suspended Solids (SS)
● Strong scalability in the later stage, including but not limited to the following parameters:
- Total nitrogen - phosphate
- Total Chromium - Hexavalent Chromium
- Iron - nickel
- Zinc - Copper
.......
Operating Principle
1. Dissolve colorimetric integrated tube
The digestion colorimetric tube is used for operation, and the digestion of the sample and the reading of the results share a reaction tube, so there is no need to transfer the liquid to the cuvette for testing.
2. Direct display of results
The absorbance of the sample is measured by using a cold light source of a specific wavelength, and the instrument system directly converts the detection result into the sample concentration value through a specific algorithm.
3. Measure and remove outliers multiple times
Measure the water sample 10 times or more, remove outliers and take an average to reduce the impact of dirt, scratches, fingerprints, or defective glass tubes on the results.
4. Detect abnormal prompts
Indicate detection anomalies, such as blank comparison prompts, result overrun upper limit prompts, etc.
