AH-Quantuv PAR Meter for Grow Lights, PPFD Meter 400-750nm with UVA Measurement 320-400nm, Shows PAR Breakdown of Blue Green Red, Records PAR & UVA for Light Distribution Mapping

Measure PAR and UVA Light Accurately. Measure PAR (400-750nm) and UVA (320-400nm) irradiance intensity to understand how your grow lights actually perform. The PAR sensor IC is manufactured by a well-known Japanese semiconductor company, delivering reliable and consistent readings for grow lighting analysis. See the PAR Breakdown of Blue, Green, and Red. Unlike most PAR meters that only show a single value, AH-Quantuv displays the PAR contribution of Blue, Green, and Red separately. This helps growers better understand the spectrum of their grow lights and optimize lighting for different plant growth stages. Understand How Spectrum Affects Plant Growth. Plants typically require more blue light during the seedling and vegetative stages, while higher red light supports flowering and fruiting. Viewing the spectrum breakdown helps growers adjust lighting to promote healthier plant development. PAR Recording Function for Light Distribution Mapping. The built-in recording function allows you to log up to 100 PAR measurements, making it easier to evaluate the light distribution across your grow area and identify hotspots or low-light zones. Multiple Display Modes & Easy Operation. Switch between screens to view PAR values, UVA irradiance intensity, RGB PAR breakdown, and historical records. The HOLD function allows stable readings for easy observation. Simple interface design makes operation straightforward. Certified Quality. CE certified for reliable performance and safety.
