No specifications are available for the QCR models, but they are identical to the QCP series except for the sensor collectors; the QCR models are designed for surface use whereas the QCP models are designed for underwater 'profiling' use. The QCR-2150 output is provided as a calibrated ASCII text data stream with optional inclusion of sensor temperature. It is designed for use with Logger 2150 software but is also suited for integration with third-party software, for example in multi-parameter monitoring systems. The QCR-2150 uses a 24 bit analog-to-digital converter with low noise and excellent stability. It is equipped with a Switchcraft EN3P5M connector. It measures over the PAR spectral range from 400 - 700 nm, and has sampling rates from 250 Hz to 1 sample average per hour. It has a dark reading stability < 0.003 uE/m2/sec (between 0 - 50 degC)."@en ; skos:notation "SDN:L22::TOOL1671" ; skos:note "accepted"@en ; skos:prefLabel "Biospherical QCR-2150 surface PAR sensor"@en ; skos:related , .
