Bộ đo mật độ cây Opti-Sciences PSK Plant Stress Kit

Includes the Y(II) meter and the FV/FM meter

Y(II) meter

Measures light adapted Y(II) protocol with an FM' correction option, PAR, ETR, Leaf temp, & Leaf absorptance

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.

Opti-Sciences developed a system that does not require expensive fiber optics, but still follows the proven methods needed for reliable plant stress measurement. Y(II) is measured from the top of the leaf along with PAR or photosynthetically active radiation. Furthermore, leaf temperature is measured from the bottom over a large area, allowing a more reliable value.

Measures the light adapted Y(II) protocol with an FM' correction option, PAR, ETR, Leaf temp, & Leaf absorptance.

Features:

  • The Y(II) meter may be purchased separately from the Plant Stress Kit
  • Y(II) measurement & ETR measurement can be corrected for leaf absorptance
  • Leaf absorptance measurement including leaf transmittance using RGB sensors
  • PAR measurement
  • Non Contact Leaf temperature measurement averaged over a large area
  • FM' correction option at high actinic light levels, according to Loriaux 2013
  • Diurnal monitoring capability designed for growth chamber work. It allows measurement day and night. Useful for laboratory work.
  • Relative humidity sensor
  • USB transfer of comma delineated files to Excel ® or other spread sheets.
