Biospherical Instruments QCR-2150 surface reference radiometer for PAR, 400-700 nm, designed for cosine irradiance measurements in air / above-water environments as part of oceanographic, limnological, meteorological, and environmental light-monitoring setups. The QCR-2150 is part of Biospherical’s 2150 digital-output series and provides a calibrated ASCII text data stream suitable for use with Logger2150 software or third-party acquisition systems. Published references for the model note a 24-bit analog-to-digital converter, low-noise stable signal handling, sampling rates from 250 Hz to 1 sample average per hour, and a Switchcraft EN3P5M connector, with optional inclusion of sensor temperature in the output stream. This is not a consumer PAR meter; it is a research-grade reference sensor used in field and vessel-based monitoring applications where stable surface irradiance data are needed for environmental measurements and correction of in-water optical data. Please review photos carefully for exact condition, connector style, included cable/accessories, serial number, and any other details.
