Chlorophyll content (SPAD) III

REQUIREMENTS: Firmware v0.41 or higher. Measures transmission at 940nm and 650nm in order to determine the 'greenness' of a leaf, an indicator of chlorophyll content and nitrogen content. The 940 is used to account for leaf thickness. Improvements over Chlorophyll content (SPAD): - performs 3 different spads at 3 intensities for thin and thick leaves - auto-chooses appropriate intensity - is calibrated to a Minolta SPAD device from factory.

Improvements over previous version -

  • Compatible with firmware v0.41 or higher.
