Product Description
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.
