4、 Four OrchidsAdvantages of SL-TJD best-selling upgraded version:

1The optical power adjustment technology adjusts the light intensity to the optimal state according to different wavelengths, while ensuring the stability of the light source.

2Using materials with good monochromaticityLED light source is used, and a monochromatic filter is used to produce a monochromatic light scheme. The absorbance linear automatic correction technology is used to test the linearity to achieve the linear effect of a grating type spectrophotometer.

3Unique automatic elimination of colorimetric dish errors functionReduce the accumulation of errors and achieve more accurate measurement results.

4Computers and microcomputers have precise calibration coefficients, conversion relationships, and linear regression equations, ensuring measurement accuracy higher than industry standards.

5The one-time combined extraction technology of multiple nutrients such as nitrogen, phosphorus, potassium, etc. in soil fertilizers is different from the conventional single item extraction method, which greatly improves the efficiency of soil fertilizer nutrient detection.

6Modular modular design for user maintenance and modelingpieceType maintenance provides maximum convenience.
