What Is the ITC Parwise Pro Light Meter?
The Parwise Pro Light Meter by ITC Reefculture is a next-generation lighting diagnostic tool that goes far beyond simple PAR readings. Designed for use in saltwater reef tanks, freshwater planted aquariums, and even commercial coral propagation systems, this compact sensor delivers:
- Real-time PAR (Photosynthetically Active Radiation)
- PUR (Photosynthetically Usable Radiation)
- LUX
- CCT (Correlated Color Temperature)
- DLI (Daily Light Integral)
- Full spectral analysis
With Bluetooth connectivity and a user-friendly app for iOS and Android devices, the Parwise Pro lets you view, record, and graph light data directly from your smartphone or tablet.
Why the Parwise Pro Is Better Than a PAR-Only Meter
1. It Measures PUR, Not Just PAR
While PAR measures the intensity of usable light between 400–700nm, not all of that light is equally effective for coral and plant growth. The Parwise Pro measures PUR (Photosynthetically Usable Radiation)—the specific wavelengths your corals or plants actually use. This gives you far more accurate insight into whether your lighting setup is truly effective.
2. Full Spectral Analysis
Unlike most PAR meters, the Parwise Pro provides a complete spectral breakdown. You can see how much blue, red, white, and UV light your fixture is emitting, allowing you to optimize your LED settings for peak coral color and growth response.
3. DLI Readings for Accurate Photoperiod Control
The Daily Light Integral (DLI) measures the total light energy your tank receives over a 24-hour period. This is a critical metric for SPS corals and freshwater plants alike. The Parwise Pro automatically calculates DLI based on real-time readings and photoperiod duration—something a basic PAR meter can’t do.
4. CCT and LUX Measurements
The Parwise Pro Light Meter also gives you Correlated Color Temperature (CCT) and LUX values. These are important for assessing the visible brightness and color tone of your lighting, which matters in both aesthetic and scientific applications.
