Features

1. The wavelength is automatically selected when measuring the sample, without adjustment. 

2. Adopt 5.0-inch large LCD screen, display in Chinese (available in English). The measured concentration is directly displayed and the absorbance is measured.

3. The instrument is convenient to carry around for on-site testing. The instrument has many functions, such as measurement, setting, recording, saving and data statistical processing. 

4. With data storage function, it can store 100 curves and 1999 data with time and parameter labels. The built-in printer enables the direct printing of the measurement results. 

5. Data interface: peripheral USB interface to support data management and instrument control. 

6. Cold light source, narrow-band interference optical system, good optical stability. Optical path system: using solid light emitting device as both light source and as monochromatic, light source / monochromatic, color slot, sensor integrated, no moving parts, pulse power supply, the service life of the light source up to 100,000 hours. 

7. Data power-off protection function. 

8. Power supply mode: dual power supply system, built-in lithium battery, and has the power self-diagnosis function, automatically prompt the power is insufficient. 

9. Online software: it can realize the input of the sample name, the tested items, testing institutions, inspection personnel and other information, and can export the text format data. Test report can be written directly, and report printing can be realized through the external printing system. 

10. With special reagents, the determination of the measured object can be realized only with the zero point correction. The operation accuracy is high, simple and fast. 

11. Expanded and customized test projects.
