Increased Accuracy for Underwater LED Lighting Measurements!

Apogee's MQ-510 PAR meter is perfect for underwater testing of LED light intensity and immersion effect correction factor has already been applied through the monitor's firmware giving you the corrected underwater value.

• Designed for underwater use
• Full Spectrum
• Works will all lighting types
• Improved spectral response
• 2-meter shielded cable

The MQ-510 Par Sensor has been specifically designed to give reliable and repeatable readings underwater with LED lighting. With an increased spectral range, and larger sensing optic you will get more precise readings with all types of lighting systems. Apogee now has the immersion correction factor installed in the meter and will automatically compensate for any effects underwater readings may have.

Apogee has calibrated the MQ-510 sensor with electronic lights that is stored in the firmware of the meter. Calibration with electronic lighting makes it the perfect PAR meter for any type of aquarium lighting. The sensor has a housing designed to be fully weather-proof and self-cleaning allowing years of service with minimal maintenance.

No more days of looking and guessing how much light is being put into your tank. Apogee is the leader in radiation sensing devices and recently introduced the MQ-510 USB Powered Quantum PAR Sensor that now corrects for underwater variables. PAR (photosynthetic active radiation) is the easiest way to measure the available light for corals to consume and use for photosynthesis. With LED lights giving more and more control to the consumer the best thing is a PAR meter that is affordable and simple to use. With PAR readings you can monitor light degradation, clarity of the water, and intensity of the lighting schedule. Most LED lights out on the market today have more power than what your corals can take and will quickly bleach out from too much light. By having a PAR meter to monitor the light intensity you will have tangible numbers to go off of, instead of just guessing.

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.
