PlantPen NDVI 310

Handheld reflectance meter with integrated GPS module, USB/Bluetooth communication and dedicated software. Measured parameter: NDVI index

The NDVI 310 measures Normalised Difference Vegetation Index, which is an important indicator of chlorophyll content in plants. The device compares reflected light at two distinct wavelengths: 660 and 740 nm.

Rugged and compact the PlantPen can be favorably used in the field, in the plant biology lab or for education. A handy leaf clip, simple two-button operation, and a bright display make the PlantPen an easy-to-use instrument that does not disturb investigated plants (no leaf detaching or damaging). It takes four AAA alkaline batteries and is supplied in a robust case.
