N-Pen N 100

N-Pen is a light-weight, battery-powered instrument that can be favorably used for effective nitrogen management in plants throughout their growing season.

Essentially, the N-Pen characterizes nitrogen amount by means of reflectance and by the concept of a close link between chlorophyll content and nitrogen content in plants.

Rugged and compact N-Pen can be favorably used in the field, in the plant biology lab or for education. The use of the N-Pen is non-destructive and permits quick, repeated measurements throughout the growing season. It takes four AAA alkaline batteries and is supplied in a robust case.

Offered are also N-Pen versions with a communication module (Bluetooth, USB, or serial) and the possibility of data transfer to a PC.
