The Z955 N- Pen is a lightweight, battery-powered PlantPen that can be used for nondestructive in vivo measurements of N content in plants. The N-Pen measures the reflectance of light at 565 and 760 nm and calculates NDGI (normalized difference greenness index) from which total N content (%). It is rugged and compact and ideal for use in the field, in a plant biology lab, or in teaching plant biology.
Z955 N pen uses a rechargeable Li-ion battery and has a memory capacity of 16 MB. Measured data are numbered and may be recalled on the LCD display in sequence after completion of the experiment. Transfer of data to a PC is possible with Bluetooth and USB module. The PlantPen is supplied with software that allows data transfer, visualization, and export into spreadsheet programs. With the built-in GPS module, it is an ideal instrument for field measurements.
