Apogee MQ-500 Full Spectrum Quantum PAR Meter

The MQ-500 is used to measure incoming PPFD measurements in outdoor environments, greenhouses, growth chambers, and aquariums. Full spectrum quantum sensor with a spectral range of 389 to 692 nm ± 5 nm. Optional accessories pictured include the AM-310 Telescoping. Extension Wand for reaching further into plant canopy (super useful) and the Apogee AC-100 USB Data Cable to connect and download to PC. Accurate, Stable Measurements Long-term non-stability determined from multiple replicate quantum sensors in accelerated aging tests and field conditions is less than 2 % per year. Rugged, lightweight and portable with a four year manufacturers warranty. Refined Spectral ResponseThe 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.Cosine ResponseThis cosine-corrected sensor is designed to maintain its accuracy when radiation comes from low zeith angles. The sensors measure PPFD with a cos
