The ODO/CT has all the advantages of optical dissolved oxygen technology – 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. The digital technology of the ProDSS allows the handheld to automatically recognize connected sensors, so there is no need to tell the instrument what is connected.
The ProDIGITAL ODO/CT probe and cable assembly features include:
