The ITC Reefculture PARwise PRO is an advanced light meter designed to give you a deep understanding of your aquarium's lighting conditions. It moves beyond simple intensity readings by utilizing innovative cPUR technology to precisely measure both the intensity and the specific spectrum of light that your corals can actually utilize for photosynthesis. This sophisticated yet user-friendly device connects to your Android mobile device, PC, or MAC, allowing you to fine-tune your light's intensity, color spectrum, and photoperiod for optimal coral health and growth.

This professional-grade meter boasts an extended spectral range from 350nm to 1100nm, detecting crucial UV-A and NUV wavelengths that influence coral coloration. A key feature is the Pigment Analysis section, which displays an absorption spectrum graph for pigments like Peridinin, Fucoxanthin, and various Chlorophylls, providing unparalleled insight into photosynthetic efficiency. With a PAR range up to 6000 µMol/m2/s, an IP68 waterproof rating, and auto-compensating temperature response, the PARwise PRO is built for accurate and repeatable measurements directly in your tank.

This device is ideal for the dedicated reef hobbyist or professional aquarist who wants to eliminate guesswork and take a data-driven approach to lighting. If you are investing in high-end LED fixtures, struggling with coral coloration, or simply want to ensure your corals are receiving the ideal light for their specific needs, the PARwise PRO provides the critical information needed. It empowers you to create the perfect lighting environment, maximizing photosynthetic activity and unlocking the full vibrant potential of your reef aquarium.
