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 (400750nm) and UVA (320400nm) 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.
Measure PAR And See the UVA + RGB Breakdown Behind It
AH-Quantuv doesn't just show total PAR. It reveals UVA and the PAR contribution of Blue, Green, and Red light.
Helping growers understand how their grow lights actually work.
UVA (320400 nm)
Check whether your grow light truly delivers UVA, which may influence plant stress response and secondary metabolite production.
Blue PAR (400500 nm)
Understand how much blue light your plants receive important for chlorophyll absorption and compact growth.
Green PAR (500600 nm)
Green light penetrates deeper into dense canopies, helping lower leaves receive usable light.
Red PAR (600750 nm)
Red light provides the primary energy for photosynthesis and strongly influences flowering and growth rate.
With AH-Quantuv, growers can measure not only how much light plants receive but what kind of light it is.
