The Gold Standard For Traditional Photosynthetic Light Measurement
The MQ-500 is a full spectrum quantum sensor with a spectral range of 389 to 692 nm ± 5 nm, which can be seen in the graph pictured. This improved spectral response increases the accuracy of LED measurements.
Refined Spectral Response
The improved spectral response of the MQ-500 increases the accuracy of LED measurements making it ideal for use with both natural and electric light sources.
This cosine-corrected sensor is designed to maintain its accuracy when radiation comes from low zeith angles. The sensors measure PPFD with a cosine response accurate within ± 5 % at 75 ° zenith angle.
Head is potted solid making it submersible and suitable for use in all climate conditions.
Warranty and Support
All Apogee products are backed by an industry-leading four-year warranty and outstanding customer support.
