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.
Currently Available Calibrations:

- Agronomy research
- Displayed is the actual nitrogen reading
- Nitrogen reading is calibrated for particular plant (here wheat and barley)
- Calibrations for other plants may be provided
- Variety or hybrid differences can greatly affect N-Pen readings
- Plant diseases, nutrient deficiencies and other kinds of plant stress can also affect N-Pen readings
- Simply insert the leaf between the leaf clip and the optical tip
- N-Pen collects and stores individual readings and calculates the average automatically
- Readings should be taken on different plants of the same species
- Readings should be taken on the 2nd (maximum 3rd) youngest leaf on each plant
- Readings should be taken on about the same location on each leaf (close to the mid part)
- FluorPen 1.0 software for data loading, processing, and visualization in a PC (optional)
- Bluetooth, USB or serial communication module (optional)
- GPS mapping plug-in
