The YSI ODO/CT probe is the first expansion of the ProDIGITAL system. The ODO/CT probe and cable assembly features integral (i.e. built-in) optical dissolved oxygen, conductivity, and temperature sensors and is available in lengths up to 100 meters. It’s perfect for measuring DO in the following applications – estuary, wetland, coastal, aquaculture, or any application requiring accurate, real-time salinity-compensated DO measurements. The ODO/CT has all the advantages of optical dissolved oxygen technology- with higher accuracy, less maintenance, no stirring required for accurate measurements, holds calibration longer than membrane covered sensors and is not susceptible to interferences from other gases. Instrument setup is quick and easy with the integral sensors, which eliminates the need to install sensors before use and digital technology allows the handheld to automatically recognize connected sensors.
