The PARwise PRO is a next-generation light meter designed to take the guesswork out of aquarium lighting. Powered by cPUR technology, it accurately measures not just intensity (PAR), but also the entire usable light spectrum from 350nm to 1100nmincluding UV and IR wavelengths. Whether youre fine-tuning your reef lights or optimizing coral placement, PARwise PRO gives you the data needed for maximum photosynthetic efficiency and coral health.

Key Features:

• cPUR spectral analysis: Understand what wavelengths your corals can actually use

• Pigment absorption insights: Visualizes how much light is absorbed by key photosynthetic pigments like Chlorophyll and Fucoxanthin

• Extended spectral range: Measures from UV-A through visible to IR (350nm1100nm)

• Supports air, freshwater, and saltwater calibration

• Measures more than PAR: Includes LUX, DLI, KELVIN, YPF, CRI, Purity, and more

• Chrome/Edge compatible software for Android, PC, and Mac (iOS not supported)

• USB OTG support for Android mobile devices

Measurements Include:

• cPUR & cPUR Light Integral

• PAR (PPFD)

• Full Light Spectrum (3501100nm)

• LUX, DLI, KELVIN

• YPF (for plant use)

• CRI, CQS, Purity, Dominant Wavelength, CIE X/Y
