The SQ-640 is sensitive enough to find leaks the eye and standard PAR sensors miss. It is a specialty sensor that over-ranges under normal grow-light levels.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eExtended range 340 to 1040 nm, optimized for low light\u003c\/li\u003e\n\u003cli\u003eDetects light leaks that disrupt plant dark periods\u003c\/li\u003e\n\u003cli\u003eHelps prevent hermaphroditism and photoperiod stress\u003c\/li\u003e\n\u003cli\u003eAnalog, SDI-12, or microCache options\u003c\/li\u003e\n\u003cli\u003eBuilt and calibrated in Logan, Utah; NIST-traceable, made in the USA, and backed by an industry-leading 4-year warranty.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhy Choose This Model\u003c\/h3\u003e\u003cp\u003eThe SQ-640 protects photoperiod integrity by finding the light leaks that cause costly crop problems.\u003c\/p\u003e\u003ch3\u003eIdeal Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDark-period light-leak audits\u003c\/li\u003e\n\u003cli\u003ePhotoperiod-room commissioning\u003c\/li\u003e\n\u003cli\u003eBlackout and light-deprivation verification\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Apogee Instruments","offers":[{"title":"Default Title","offer_id":52354478407991,"sku":"SQ-640-SS","price":459.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/0341\/5863\/files\/SQ-620-640-front__61967.1582046487.jpg?v=1780698017","url":"https:\/\/www.blacklabelsupply.io\/products\/apogee-instruments-sq-640-ss-quantum-light-pollution-sensor","provider":"BLACK LABEL","version":"1.0","type":"link"}
