It tracks:\u003cbr\u003e✔ PAR (Photosynthetic Light) – The type of light (400-700nm) plants use for growth.\u003cbr\u003e✔ DLI (Daily Light Integral) – The total amount of light your plants receive in a day.\u003cbr\u003ePlants rely on photosynthetically active radiation (PAR) within the 400-700nm spectrum to fuel photosynthesis. While sufficient light in this range is essential for growth, excessive exposure can lead to photoinhibition. Whether you're a home gardener, commercial grower, or plant scientist, this tool helps you monitor and optimize PAR levels, ensuring your plants receive balanced light intensity for optimal health and yield.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMeasure PAR (Photosynthetically Active Radiation) flux and DLI (Daily Light Integral)\u003c\/li\u003e\n\u003cli\u003eRecords up to 5 years of data and can export in CSV file\u003c\/li\u003e\n\u003cli\u003eConnect to PC via USB Type-C cable\u003c\/li\u003e\n\u003cli\u003eEasy to read 30 days of data in the main unit\u003c\/li\u003e\n\u003cli\u003eDate and Real-time clock Display\u003c\/li\u003e\n\u003cli\u003eDLI (Daily Light Integral) function\u003c\/li\u003e\n\u003cli\u003eIP65 Waterproof\u003c\/li\u003e\n\u003cli\u003eBattery level indicator\u003c\/li\u003e\n\u003cli\u003eManual and Automatic power-off function\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePPFD Measurement:    \n\u003cul\u003e\n\u003cli\u003eRepeatability: ±1μmol\/m2\/sec\u003c\/li\u003e\n\u003cli\u003eMeasurement Range: 0~5000 μmol\/m2\/sec\u003c\/li\u003e\n\u003cli\u003eDisplay Resolution: 0.01 μmol\/m2\/sec(0-99.99); 0.1 μmol\/m2\/sec(100-999); 1 μmol\/m2\/sec(1000-5000)                    \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eMeasuring Rate: 1 measurement per second\u003c\/li\u003e\n\u003cli\u003eCut-On Wavelength: 400±10nm\u003c\/li\u003e\n\u003cli\u003eCut-Off Wavelength: 700±10nm\u003c\/li\u003e\n\u003cli\u003eOperating Condition: 32~22°F (0~50°C);  0-95%RH, non-condensing\u003c\/li\u003e\n\u003cli\u003eStorage Condition: -4~140°F (-20~60°C);  0-95%RH, non-condensing\u003c\/li\u003e\n\u003cli\u003ePower Requirements: 2pcs AAA alkaline battery\u003c\/li\u003e\n\u003cli\u003eDimension: 115 x 60 x 24 mm\u003c\/li\u003e\n\u003cli\u003eWeight: 115g \/ 0.25pounds (without batteries)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSet Includes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e1 x PAR Meter\u003c\/li\u003e\n\u003cli\u003e1 x Type-C Cable\u003c\/li\u003e\n\u003cli\u003e2 x AAA batteries\u003c\/li\u003e\n\u003cli\u003e1 x Soil rod\u003c\/li\u003e\n\u003cli\u003e1 x Screwdriver\u003c\/li\u003e\n\u003cli\u003eEnglish Instruction Manual\u003c\/li\u003e\n\u003cli\u003eStandard Factory Packaging\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"A06","offers":[{"title":"Default Title","offer_id":43067239039019,"sku":"ILLX-499","price":74.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/5850\/1675\/files\/par-499-digital-dli-meter-datalogger-plant-light-for-growers-measures-daily-integral-400-700nm-photosynthetic-ideal-hydroponics-greenhouses-indoor-gardening-556.jpg?v=1770633130","url":"https:\/\/instrulife.com\/products\/illx-499","provider":"Instrulife","version":"1.0","type":"link"}
