The Apogee Instruments SQ-520 Full-Spectrum Smart Quantum Sensor is a USB powered sensor that will hook up to any PC or MAC allowing you to use your personal computer instead of an expensive dedicated monitor with the included 15 foot long USB cable. Hooking a sensor up directly to your computer allows you to easily log readings within the Apogee software or any application of your choice.
The SQ-520 Par Sensor has been specifically designed to give reliable and repeatable readings under LED lighting. With an increased spectral range, and larger sensing optic you will get more precise readings with all types of lighting systems. If you do not have a computer near your tank, don't worry, the SQ-520 can store up to 10,000 measurements internally and viewed later when powered by a stand-alone 5v USB power adapter like a battery pack or wall adapter.
Apogee has calibrated the SQ-520 with electronic lights making them perfect for any type of aquarium lighting. Calibration will be stored within the firmware of the sensor. The sensor has a housing designed to be fully weather-proof and self-cleaning allowing years of service with minimal maintenance.
