Hooking a sensor up directly to your computer allows you to easily log readings within the Apogee software or any application of your choice.\n\u003cbr\u003e\u003cbr\u003e\nThe 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.\n\u003cbr\u003e\u003cbr\u003e\nApogee 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.\n\u003cb\u003e\u003cspan style=\"font-style: italic;\"\u003eFeatures:\u003c\/span\u003e\u003c\/b\u003e\n\u003cul\u003e\n\t\u003cli\u003e\u003cspan\u003e Product Manual  (pdf in new window)\u003c\/span\u003e\u003c\/li\u003e\n\t\u003cli\u003e\u003cspan\u003eResolution - 0.1  µmol m-2 s-1\u003c\/span\u003e\u003c\/li\u003e\n\t\u003cli\u003e\u003cspan\u003eCalibration Factor - custom for each sensor and stored in the firmware\u003c\/span\u003e\u003c\/li\u003e\n\t\u003cli\u003e\u003cspan\u003eCalibration Uncertainty -  ± 5 %\u003c\/span\u003e\u003c\/li\u003e\n\t\u003cli\u003e\u003cspan\u003eMeasurement Repeatability - less than 1 %\u003c\/span\u003e\u003c\/li\u003e\n\t\u003cli\u003e\u003cspan\u003eField of View - 180°\u003c\/span\u003e\u003c\/li\u003e\n\t\u003cli\u003e\u003cspan\u003eSpectral Range - 389 nm to 692 nm (wavelengths where response is greater than 50% of maximum)\u003c\/span\u003e\u003c\/li\u003e\n\t\u003cli\u003e\u003cspan\u003eDimensions - 2.4 cm X 3.7 cm high\u003c\/span\u003e\u003c\/li\u003e\n\t\u003cli\u003e\u003cspan\u003eUSB Cable - 4.6 m (15 ft)\u003c\/span\u003e\u003c\/li\u003e\n\t\u003cli\u003e\u003cspan\u003eCurrent Draw (when Logging) - 5.1 mA\u003c\/span\u003e\u003c\/li\u003e\n\t\u003cli\u003e\u003cspan\u003eWarrantied for 4 years against defects in materials and workmanship\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VASCAAquariumSupply","offers":[{"title":"Default Title","offer_id":42621018964053,"sku":"RAO00004","price":436.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0646\/2626\/2101\/files\/AO00004-2.jpg?v=1781983951","url":"https:\/\/vascaaquariumsupply.com\/products\/apogee-instruments-sq-520-full-spectrum-smart-quantum-sensor-usb","provider":"VASCAAquariumSupply","version":"1.0","type":"link"}
