Biospherical Instruments QCR-2200 Surface Reference Radiometer, Serial No. 20311. This weather-resistant surface PAR sensor is designed to measure cosine irradiance from sunlight over the 400 to 700 nm photosynthetically active radiation band and is commonly used with CTD systems, oceanographic profilers, shipboard incubation setups, and environmental data logging systems that require an analog voltage input. The QCR-2200 is a non-submersible reference radiometer optimized for above-water use and is commonly paired with Biospherical underwater cosine profilers to provide surface reference PAR data during water-column light measurements. Features include cosine-response acrylic collector, analog voltage output, NIST-traceable calibration architecture, and compatibility with CTD and marine research workflows. Ideal for oceanography labs, limnology programs, marine field research, environmental monitoring, and replacement of legacy Biospherical PAR instrumentation. Please verify connector style, cable, status, and integration requirements before purchase.
