Description

TES-1339P Data Logger Light Quantum Meter
Description
Autoranging 5 steps and conversion to μmole/m2/s (PPFD: Photosynthetic Photon Flux Density).
Integral illuminance measurement and conversion to mole/m2/d (Daily light integral).
Luminous intensity measurement.
Point - average function.
Spectral correction factor function. (include LED)
TES 1339P Data Logger Light Quantum Meter is a precision instrument used to measure illuminance (lux, footcandle) and photosynthetic photon flux density (PPFD μmole/m2/s) in the field.
It meets CIE photopic spectral response, f ’1 ≦6%.
It is fully cosine corrected for the angular incidence of light.
The illuminance meter is compact, tough and easy to handle owing to its construction.
The light sensitive component used in the meter is a very stable, long-life silicone photo diode and spectral response filter.
