- MQ-210 Underwater Quantum PAR Meter - Apogee
Increased Accuracy for all Underwater Lighting Measurements!
Measure and store the PAR (photosynthetically active radiation) readings of your reef tank to ensure the healthy growth of your inhabitants.
- Handheld meter with large, easy to read LCD display
- Records reading for review
- Record measurement in Automatic mode or Manually
- Separate sensor head is fully potted, dome-shaped design - waterproof, weatherproof and self-cleaning
The MQ-210 Par Sensor has been specifically designed to give reliable and repeatable readings underwater with all types of natural and electronic lighting. Apogee now has the immersion correction factor installed in the meter and will automatically compensate for any effects underwater readings may have.
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.
We personally like inputting all of our reading into a spreadsheet to make a chart of light output and overlay the readings on a photo as well. Having a picture with your tanks PAR levels is very handy to have when placing new corals in your tank.

1x Apogee MQ-210 PAR Meter and Sensor
I need to know the differences MQ-200 and the MQ-210? And what would be better to measure PAR to an T5 lighting?
Excluding LEDs, the MQ210 will be the best bet and most accurate measuring device for taking measurements of electronic sources of light under water. The MQ200 is the previous model which did not have internal corrections for underwater measurements, but is also the unit most commonly used by hobbyists up to this point, and what you will find most posted measurements are taken from.
Hope this helps! Have a great day!
