The PARwise PRO is an advanced light meter that revolutionizes aquarium lighting management. Its innovative cPUR technology precisely measures both intensity and spectrum to determine exactly what light corals can utilize. This sophisticated yet user-friendly device provides deep insights into your lighting conditions, allowing you to perfectly fine-tune settings. It is compatible with Android mobile devices supporting USB OTG, PC, and MAC platforms. The companion software runs on Google Chrome or Microsoft Edge browsers (both free). Unfortunately, iPhone and iPad compatibility is not yet available. Note: *Mobile device, PC or tablet is required to operate but not included. Features: Determines optimal light settings, including intensity, color spectrum, and photoperiod Features cPUR technology that measures both intensity and spectrum Extended spectral range detecting UV-A and NUV wavelengths from 350nm to 1100nm New Pigment Analysis section displays an absorption spectrum graph and percentages for Peridinin, Fucoxanthin, Chlorophyll A, B, C, D, and Beta-carotene to aid in understanding photosynthetic efficiency. Includes specific calibrations for air, freshwater, and saltwater environments Can detect heat waste and wasted energy within the IR range Includes YPF measurement (cPUR equivalent for plants) Helps achieve perfect growth rates by measuring correct wavelengths, intensity, and duration Compensates for the human eye's inability to assess light levels and colors accurately Valuable tool for determining optimal coral placement when adding new specimens Worth the investment if it saves just one coral PARwise Pro Measures: cPUR Spectrum -Detect NUV down to 350nm - 380-1100nm PAR LUX DLI cPUR Light Integral KELVIN YPF CQS CRI PURITY Dominant Wavelength CIE X/Y Specifications: PAR Range: 0-6000 µMol/m2/s Kelvin: 1000-10,000 Kelvin LUX: 2-300000 Spectrum: 350-1100nm Optical Measurement Type: Point light source Accepted light sources: Natural, LED, Fluorescent, Incandescent, Gas Vapour, HID Measurement repeatability: < 0.5% Calibration Uncertainty: +- 5% Directional cosine corrector: Replaceable Temperature response: Auto compensating Ingress Protection Rating: IP68 Dimensions: 85x40x20mm
