LI-COR Radiation Sensors: Type 'SA' (e.g. LI-190SA)
with BNC connectors.
LI-190SA Quantum Sensor - measures Photosynthetically
Active Radiation (PAR) in natural sunlight, under plant
canopies, and in growth chambers and greenhouses.
LI-191SA Line Quantum Sensor - averages PPFD over its
one meter length for plant canopy PPFD profile studies.
LI-192SA Underwater Quantum Sensor* - measures
Photosynthetic Photon Flux Density (PPFD) in air or under
water incident on a flat plane.
LI-193SA Spherical Quantum Sensor* - measures photon
flux from all directions under water. This measurement is
called Photosynthetic Photon Flux Fluence Rate (PPFFR).
LI-200SA Pyranometer Sensor - measures global solar
radiation (sun plus sky) and provides a typical accuracy of
±
5% under unobstructed daylight conditions.
LI-210SA Photometric Sensor - measures visible radiation
and has a spectral response equal to that for the average
human eye. Readout of illuminance (in lux) is used for
lighting studies or architectural modeling.
* Requires 2222UWB cable.
