Revolutionary cPUR Technology Measures What Corals Actually Use
The PARwise PRO replaces outdated PAR measurements with cPUR (Coral Photosynthetically Usable Radiation), a groundbreaking technology that measures only the wavelengths and intensities corals can actually use for photosynthesis and growth. With an extended spectral range of 350nm to 1100nm (Near UV-A through infrared), it reveals wasted energy, detects heat waste, and provides pigment-level analysis to help you optimize every aspect of your lighting. Compatible with Android, PC, and Mac, and precise enough to pay for itself by saving just one coral.
Highlights:
- Revolutionary cPUR measurement — coral-specific usable light, replacing outdated PAR
- Extended 350–1100nm spectral range — Near UV-A through infrared
- Pigment analysis — Peridinin, Fucoxanthin, Chlorophyll A/B/C/D, Beta-carotene
- 12+ measurement parameters — cPUR, PAR, LUX, DLI, Kelvin, CQS, CRI, YPF, and more
- Environment-specific calibrations — air, freshwater, and saltwater
- Detects heat waste — identifies inefficient lighting in the IR range
- Optimal coral placement — map light zones and match corals to their requirements
- YPF measurement included — cPUR equivalent for planted aquariums
- Lab-grade accuracy with a user-friendly browser-based interface (Chrome or Edge, free)
- Works with Android (USB OTG), Windows PC, and Mac — device not included
- ⚠️ Not compatible with iPhone or iPad
Why cPUR Outperforms PAR
Traditional PAR meters measure total photosynthetic light without distinguishing usable wavelengths — you can have high PAR readings that are essentially useless to your corals. cPUR weights measurements by coral pigment absorption, giving you a true picture of the light your corals can actually utilize. The result: smarter placement, better growth, and no more guessing.
PARwise PRO is Ideal for:
- Reef aquarists optimizing coral growth and coloration
- SPS and LPS coral keepers seeking spectrum optimization
- Professional coral propagation and farming operations
- Planted aquarium enthusiasts (YPF measurement included)
- Aquarium stores and lighting manufacturers
