The MQ-500 is Apogee Instruments’ new quantum meter with an improved spectral response, providing accurate PAR/PPFD measurements under all light sources, including LEDs.

  • 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.
  • Rugged Design
    Head is submersible and suitable for use in all climate conditions.
  • Excellent Cosine Response
    Sensors measure PPFD with a cosine response accurate within ±5% at 75° zenith angle.
  • Reliable Accuracy
    To ensure accuracy, each sensor is carefully calibrated in controlled conditions, traceable to NIST reference standards.
