{"product_id":"apogee-instruments-sq-420x-smart-quantum-sensor-usb","title":"Apogee Instruments SQ-420X Smart Quantum Sensor, USB","description":"The Apogee Instruments SQ-420X Smart Quantum Sensor, USB, can be connected directly to a computer (Windows or macOS X) for taking spot measurements or graphing and datalogging real-time PPFD using the included ApogeeConnect software. The sensor can also act as a stand-alone PAR datalogger by simply connecting it to most standard 5 V DC USB power plugs. Internal memory within the sensor head is capable of storing 10,000 user-specified periodic measurements that can be downloaded as a CSV file to a computer for analysis.\n\u003cbr\u003e\u003cbr\u003e\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\u003e\n\tResolution - 0.1  µmol m-2 s-1\u003c\/span\u003e\u003c\/li\u003e\n\t\u003cli\u003e\u003cspan\u003e\n\tCalibration Factor - custom for each sensor and stored in the firmware\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 - 410 nm to 655 nm (wavelengths where the response is greater than 50% of the maximum; see Spectral Response Graph in Images)\u003c\/span\u003e\u003c\/li\u003e\n\t\u003cli\u003e\u003cspan\u003eDimensions - 2.4 cm X 2.8 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":42621018931285,"sku":"RAO00003","price":259.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0646\/2626\/2101\/files\/AO00003-2.jpg?v=1781983951","url":"https:\/\/vascaaquariumsupply.com\/products\/apogee-instruments-sq-420x-smart-quantum-sensor-usb","provider":"VASCAAquariumSupply","version":"1.0","type":"link"}
