Quantum Amplified Sensors
Quantum sensors are calibrated for electric light or sunlight.
Photosynthetic Photon Flux (PPF) in µmol m-2 s-1, blue lens filters spectra for improved response
Our basic quantum light sensor with cosine-corrected head has a domed diffusion disk and head for improved self-cleaning characteristics and long-term stability.
An innovative blue lens improves the accuracy of these sensors and meters. The pigments in the lens filter incoming light for an improved spectral response.
Sensors are calibrated for use with electric lights or sunlight. If both are present in your application, such as in a greenhouse, we recommend the sunlight calibration.
QUANTUM SENSORS and LINE QUANTUM SENSORS are designed for use with dataloggers
