▲ 13. The software automatically calls the standard curve and extraction ratio, without the need to input parameters. It can be turned on to zero and measured in blank, directly reading the oil concentration in water without manual calculation;

（3） Technical advantages

1. Using ultraviolet radiation225nm detection, capable of automatically measuring absorbance and calculating water sample concentration;

2. The instrument has a preset standard curve and can enter without configuring a standard solutionLine detection;

3. Specialized UV grating, shining wavelength225nm， Used for oil analysis scanning;

   ▲17.The built-in automatic extractor adopts a drum type three-dimensional magneticStrong stirring extraction technology, fully enclosed extraction. Special pre-processing equipment is requiredBox, realizing automatic liquid addition, extraction, separation and other automatic water sample processing, The processed water sample is directly measured on the machine.

4. Equipped with the function of automatically creating regression curves, it can be directly calculated without the need for manual calculation Add and expand new detection projects, which can be supported by multiple options7-point fitting, the fitted curve can be saved for a long time for easy retrieval in the future;

5. Equipped with automatic statistical analysis, storage and other functions, and a dedicated communication interface Equipped with specialized software for water quality testing, it is easy to transfer data to a computer Conduct summarization and mathematical statistics;

6. The sampling bottle has a scale display, and the extraction method without sample separation is in compliance with the standardHJ/T91-2002， The extraction results are consistent with the results of the national standard method;

7. Can directly use the built-in battery or220V AC power, can also be connected to a 12V DC power box or car power supply;

   ★ (4) Configuration requirement: 1 water sample extractor; One mainframe suitcase; 1 touch screen control terminal (built-in 11 inch); 1 set of colorimetric dishes; 1 extraction bottle (500ml); One copy of the instruction manual, one copy of the certificate of conformity, and one copy of the warranty card.
