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

PlantPen/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.

Key Features

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


  • Quick and easily repeatable measurements
  • Battery-operated
  • Integrated GPS module

PlantPen/N-Pen N 110

PlantPen/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 used for plant biology research or for education. Due to an inbuilt GPS module and splash-proof cover is N-Pen suitable for field experiments. The measurement is non-destructive and permits quick, repeated monitoring throughout the growing season.

The device is equipped with rechargeable Li-ion battery. Measured data are sequentially stored in the internal N-Pen memory. Data transfer is via USB or Bluetooth communication. 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
  • Barley


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

PlantPen/N-Pen N 110 MEASURES


  • Nitrogen content in percentage is correlated with Normalized Difference Greenness Index: NDGI = (R780 – R560)/(R780 + R560)

SOFTWARE


  • FluorPen 1.1 software (Windows 7, or higher compatible)
  • Bluetooth and USB communication
  • Visualization and data transfer routines to Microsoft Excel (optional)
  • GPS mapping
