Measure and record Chlorophyll N measurements in just seconds with the SPAD 502 Meter – now exclusively available with or without a built-in data logger!
Assess nitrogen needs by comparing in-field SPAD readings university guidelines or adequately fertilised check or reference strips. Research shows a strong correlation between SPAD measurements and leaf N content. You benefit by increasing reducing costly under/over fertilising, increasing N-efficiency and producing healthier, higher-yield crops.
The SPAD 502 meter can be purchased with or without a built-in data logger. The data logging version (Item 2900DL) allows you to compile readings for statistical analysis. Includes an RS-232 port for communicating with a PC* and/or portable GPS receiver**. Use geo-referenced data to correlate N measurements to yield maps or download the data into mapping software.
