- PRR-800 and PRR-2600 systems combine precision radiance and irradiance optics, high-performance data acquisition systems, and surface-mount electronics in a compact, rugged design. The PRR-800 is a 15–19 waveband, SeaWiFS-compliant reflectance radiometer. The less-expensive PRR-2600 is equipped with 8 reflectance wavebands. The instrument is intended to be lowered by hand from a vessel, supported from its own data cable, with the output from the sensors available in real time on a Microsoft Windows compatible computer. Accessories, such as lowering frame, free-fall system, and underwater shielded Kevlar cable, must be ordered separately. A typical PRR system would include both the submersible PRR, a radiometrically matching surface reference sensor (810 or 2610), deployment system (frame or free-fall), cables, and battery powered deckbox (included with PRR). An entire system can be battery-powered, assuming that the required PC is also battery-powered.
- High speed (20 Hz), very wide dynamic range (10 decades)
- PRR-800 standard 15 wavelengths per end, expandable to 19 wavelengths per end
- PRR-2600 standard 8 wavelengths per end
- Small, rugged, lightweight, battery-powered
- Choose between approximately 30 available wavelengths
- Highly flexible configurations: downwelling irradiance (Ed), upwelling radiance (Lu) or upwelling irradiance (Eu)
- Hand deployed, free-fall, or split designs (PRR-800 only) for turbid waters
- Additional PRR heads may be daisy-chained to support hyperspectral research
- Available with radiometrically matching surface sensor (PRR-810 or PRR-2610)
- Requires only a single COM port for both instruments
- Cosine collector design is optimized for use underwater or in air
