The Y(II) meter was designed to provide an inexpensive way to measure the fast light adapted Y(II) or ΔF/FM‘ protocol and to make it available to more people that need it.
- Y(II) or ΔF/FM’ with the option for FM’ correction according to Loriaux 2013 included. ETR, PAR, leaf temperature, relative humidity, leaf absorptance, FS, FM’ and FT.
- Light sources : White LED saturation flash to 7,000 μmoles.
- Sensors : 2 RGB sensors for measurement of leaf reflectance, leaf transmittance, and leaf absorptance, calibrated with standard.
- Memory : 2 Gigabytes
