N-Pen N 100

N-PenN-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.

N-Pen Features:

  • Lightweight, hand-held design.
  • Non-invasive measurement method.
  • Easy two-button operation.
  • Quick and easily repeatable measurements.
  • Battery-operated.

N-Pen Applications:

  • Significant yield increase.
  • Quick tuning of nitrogen management in crops.
  • Increasing nitrogen use efficiency.
  • Reducing the risk of yield-limiting N deficiencies.
  • Saving labor and/or application costs.
  • Reducing the risk of excessive fertilizer applications and subsequent contamination of the environment.
  • Agronomy research.

N-Pen Reading:

  • 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.

N-Pen Sampling:

  • 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).
