Soil/fertilizer Nutritional Parameters Product introduction
HLY-TR05 is a multi light source testing system independently developed by our company. It adopts the filter photoelectric colorimetry technology. Due to the poor monochromaticity of the filter, the general linear error is large, and the national standard allows 3-8%. Hly-tr05 has reduced the error to 1-3% by improving the optical path design and intelligent microprocessor technology, and has reached the precision level of grating spectrophotometer, Reduced weight and cost.

Product Features:
1. High precision: the conventional soil nutrient instrument generally adopts the filter photoelectric colorimetry technology. Due to the poor monochromaticity of the filter, the general linear error is large, and the national standard allows 3-8%. Hly-tr05 has reduced the error to 1-3% by improving the optical path design and intelligent microprocessor technology, which has reached the precision level of grating spectrophotometer, reducing the weight and cost.
2. Equipped with the function of soil moisture measurement: in order to measure the nutrients of fresh soil, it is necessary to know the water content. Hly-tr05 has added the newly developed capacitive water sensor to quickly measure the water content of soil samples.
3. Extraction technology: the three nutrients of fast acting n, P and K in soil can be extracted at the same time, greatly simplifying the pretreatment work.
4. Anti interference ability: if there is special interference in a certain soil in the routine analysis, the experimenter can often add some treatment or choose another analysis method, but the quick test does not have this condition, so the quick test method and reagent formula must have strong soil adaptability and anti-interference ability. In this aspect, we have done a lot of research and optimized the reagent formula.
