Apogee Instruments MQ-200 Quantum Separate Sensor with Handheld Meter


Quatum refers to the amount of energy carried by a photon. Apogee quantum sensors measure photosynthetically active radiation or photosynthetic photon flux (PPF). Photosynthetically active radiation (PAR), or photosynthetic photon flux (PPF), is the spectral range (wave band) of solar radiation from 400 to 700 nanometers that photosynthetic organisms are able to use in the process of photosynthesis.

    I am the lucky one having 2 Li-COR quantum sensor units, bunch of photospectrometers building kinetic flurimeters & stuff (check photosynq.org)...
    Now i compared it with Li-cor and i.e. when using 660 monochromatic light source (LED-actinic) or blue errors are huge exceeding 80%, it is calibrated for sunlight spot on, but for FL it is 10% off (i have done correlation for FL with LI190/LI-250 f(x)=0.904-5.94
    r^2 0.999
    for that reason i have printed spectral sensitivity curve and correlation and keep that in the box all the time.
    So spectraly it is meh 2-3stars, linearity is nice, it is small practical, looks good (better then Li-cor looks and functionality are great) waterproof (great)...
  • Very nice and compact By Reef&Frag on 12/10/2014

    I have been very happy with this unit. Very simple and easy to use. After watching some videos online it seemed like it worked better as a relative measurement than a precise reading. Overall very happy with my purchase.
  • Great for PAR By NE Patriots Fan on 4/3/2014

    Very good if you want to get serious about your lighting. This gives you great results and is easy to use. PAR is very important if you have a reef tank. This is a good meter to use to see where your lights stand. I bought one 8 year ago and still use it today.
  • Nice unit By Chicago on 3/25/2014

    I use this to track loss of light not necessarily the exact par. Works as described. Might want to research it's ability to read all blue led
  • Great product By ReefDVMs on 5/13/2013

    When switching over to LEDs and or moving coral via one system to another i have found this device to be very valuable, works well and waterproof sensor is prefect
