N-Pen

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.

Lightweight, hand-held design

Non-invasive measurement method

Easy two-button operation

Quick and easily repeatable measurements

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
