The ProODO dissolved oxygen instrument has been discontinued. YSI will continue to support existing ProODO systems through 2023 as long as parts are available. ProODO field cables, the ProOBOD assembly for the lab, and sensor caps for these assemblies (ODO cap, OBOD cap) are still available.
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.
The ProODO instrument meets the demands of true field work. The instrument is rated waterproof to IP-67 standards even without the battery cover on and the cable disconnected. Our rigorous instrument testing includes 1-meter drop tests from all angles to ensure field-durability. Other tough features include:
EPA Approved Methodology
The optical BOD (OBOD) sensor utilizes EPA approved methodology for wastewater compliance reporting of BOD and CBOD, while ODO probe/cable assemblies utilize EPA approved methodology for compliance reporting of DO.
Connect any length cable and probe to the ProODO digital instrument and use the convenient cable management kit to keep everything simple and organized. Convenient features include:
