Overview

2 year development of the Tree Health Calculator methodology during the Beta program and PhotosynQ expert program

This version utilized the 3d printed Multispeq BETA prototype

Protocols

The One Protocol (Phi2, PSI, NPQ) II

The One Protocol to rule them all! Phi2, PSI, NPQt, combined!

Changes from previous The One protocol: - no longer outputs signal from the far red period, which simplifies the signal output for the user - changed distance between measuring pulses from 10,000 to 2,000 which improves measurement resolution - has an initial stabilization peri...

Chlorophyll content (SPAD) I

REQUIREMENTS: Firmware v0.38 or lower (used for older devices which do not have a SPAD calibration, generally device ID 87 and lower).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.
