N-Pen
Quick, reliable and easy measurements in the field or laboratory
About...

The N-Pen N 110 is a light-weight, battery-powered reflectance-based instrument that provides a convenient, cost-effective method for effective nitrogen management in plants throughout their growing season. The N-Pen measures nitrogen content by a reflective index that links chlorophyll content and nitrogen content. The rugged and compact design of the N-Pen is ideal for use in the field, in the research lab or for education.

Measurements using the N-Pen are non-destructive and permit quick, repeated monitoring of nitrogen content throughout the growing season. The device is powered by a Li-ion rechargeable battery and it is housed in a robust case. It is equipped with both USB and Bluetooth communication. Comprehensive FluorPen 1.1 software provides data transfer routines and many additional features for data presentation in tables and graphs.

Key Features

  • Lightweight, hand-held design
  • Non-invasive measurement method
  • Easy two-button operation


  • Quick and easily repeatable measurements

N-Pen

N-Pen N 110 is a light-weight, battery-powered reflectance-based instrument that provides a convenient, cost-effective method 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 feld, 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 batteries and is supplied in a robust case. N-Pen features both USB and Bluetooth communication module for data transfer are available. Comprehensive FluorPen 1.1 software provides data transfer routines and many additional features for data presentation in tables and graphs.

Currently Available Calibrations:


  • Maize
  • Wheat

APPLICATIONS


  • Significant yield increase
  • Increasing nitrogen use efficiency
  • Reducing the risk of yield-limiting N deficiencies
  • Reducing the risk of excessive fertilizer applications and subsequent contamination of the environment

N-PEN MEASURES


  • Nitrogen content correlating with Normalized Difference Greenness Index:
  • NDGI = (R780 – R560)/(R780 + R560)
  • Nitrogen content displayed as %
