ClearWater Sensors Phosphate Sensors

The National Oceanic and Atmospheric Administration (NOAA) is seeking information from potential vendors for a ClearWater Sensors Phosphate Sensor with Cartridge and USB Programming Cable. The sensor will be used by the Great Lakes Environmental Research Laboratory (GLERL) to measure active Phosphorus in the water, which will help refine the HABs prediction model. The sensor must meet specific requirements, including being compact, weighing less than 6.8 kg, and having a detection limit of less than or equal to 0.02 uM. The vendor must provide software and communications cables, and the sensor must be able to record at least 1GB of memory. The delivery schedule is 30 days after the date of award. Some key features of the required sensor include: • Compact size, not exceeding 56 cm height and 16 cm width • Weight less than 6.8 kg in air with reagents on board • LED wavelength of 870 nm • Power consumption not exceeding 1.8W at max capacity • RS233/RS485 communications output • Detection limit of less than or equal to 0.02 uM • Range of zero to 100 uM • Internal recording of at least 1GB of memory • Sample rate of at least a sample/6 minutes • Reagents enclosed in plastic cartridges • Ability to record 1000 samples at a minimum • Depth rating of 6000m • Operation within a temperature range of 0-35 deg C • Waste stored in on-board canister • Deployment cable (open tail) 5 meters in length
