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.\u003c\/p\u003e \u003cbr\u003e \u003cp dir=\"ltr\" style=\"margin-top:0; margin-bottom:0;\"\u003eLM\u003c\/p\u003e","brand":"Lab Liquidators Store","offers":[{"title":"Default Title","offer_id":53449726722340,"sku":"SP111116472","price":349.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/5289\/2964\/files\/406873390384-0.jpg?v=1777377385","url":"https:\/\/store.labliquidators.com\/products\/biospherical-instruments-inc-qcr2150-surface-refer-radiometer-serial-50120","provider":"Lab Liquidators Store","version":"1.0","type":"link"}
