DO Meter Portable type with Probe, ProODO

The YSI ProODO and ProSolo dissolved oxygen meters utilize ODO® technology, an optical-based sensor, to measure dissolved oxygen. Optical-based sensors drift less than membrane-covered sensors and are capable of holding their calibration for several months. In addition, ODO sensors require less maintenance, as there are no membranes to change and no electrodes to polish. ODO is a non-consumptive technology – oxygen is not consumed during the measurement. Therefore, no stirring is required for accurate measurements, resulting in accurate data collection every time.
