Which is a good seller of plant nutrition analyzers

Plant nutrition analyzer

SCY-SPAD+

Instrument Features：

data measurement：Measurement accuracy and repeatability(Accuracy:± 1.0 SPADRepeatability:±0.3 SPAD)Customers can calibrate themselves based on leaves or standard samples with known chlorophyll content.

data grouping：The instrument can automatically group data and calculate the average value of each group of data. The data measured on the same blade can be automatically grouped together for easy viewing of each measurement and the average value of this group, effectively avoiding confusion of measurement data for different blades.

data browsing：You can browse the measured data, the average value of each group of data, and delete outliers at any time on the instrument.

Data export：The instrument can be directly connected to the computer, and the data can beEXCELFormat export, no need for upper computer software, simple and convenient operation.

display：high contrastLCDDisplay screen, can clearly display data even under strong light.

Quick and easy measurement：When measuring, simply insert the leaves and close the measuring probe. There is no need to pick the leaves, which does not affect the normal growth of the crop. Specific leaves can be monitored throughout the growth process of the crop to obtain more scientific analysis results.
