| Definition | A cosine-corrected Photosynthetically Active Radiation (PAR) quantum irradiance profiling sensor for use in underwater applications. A variant of the QCP-2300 model, it uses a pressure-tolerant XSG-4-BCL-HP connector and is designed for operation in natural waters up to 6800m in depth. The sensor has a flat quantum response over the PAR spectral region (400-700nm) with the spectral response being shaped by a combination of absorbing glass and custom dichroic filters to accurately cover the PAR spectral region and block out-of-band radiation. Ideal to measure light available for photosynthesis on a flat surface. Custom-housed versions are available for gliders and other undersea monitoring applications. Low power consumption of <5mA at 6-15 volts DC and can operate in a temperature range of -2 to 50 degrees Celsius. Uses a 24‐bit analog to digital converter to sample the signal before the logarithm is computed and the result is converted into an analog voltage (0‐5 V). | |
