RBRquadrante: four-channel radiometer

The RBRquadrante is a multi-spectral radiometer with four channels, capable of measuring multiple wavebands simultaneously, including PAR. It features a high dynamic range, optimized cosine response, and excellent low-light detection, while power consumption and depth rating have been tailored for use in a wide variety of applications.

The RBRquadrante supports measurement of four wavebands within the same sensor package. Tolerant of a wide ranging power supply, data are streamed via RS-232 on the MCBH-6-MP connector. A variety of adaptors make it easy to integrate into existing vehicle payload bays.
