Overview
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 direct replacement for the ProODO is the ProSolo. For more information on the ProSolo, we recommend checking out the ProODO and ProSolo Comparison Guide, as well our blog on the Top 8 Reasons to Upgrade from the ProODO to the ProSolo.
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.
Field Worthy
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:
- 3-year instrument warranty and a 2-year cable and probe warranty
- Metal Military Spec (MS) connectors
- Rubber over-molded case
- Field tested cables
- Rugged, weighted probe guard
- Made in the USA
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.
Versatile
The ProODO provides versatility with numerous benefits from the following features:
- 5,000 data-set memory
- Expanded DO range of 0-500% (0-50 mg/L)
- OBOD optical, self-stirring BOD probe for the lab
- One instrument for the lab and field
- Calibration password protection
- Backlit display and keypad
- Graphic display visible with polarized sunglasses
- Multiple languages (see specifications)
- 100 folders and site lists for logging data with user defined fields
Convenient
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:
- Cable options from 1- to 100-meters including a cable management kit on 4-meter and longer cables; laboratory BOD probe
- Detailed on-board Help
- Detailed GLP data (calibration records)
- Digital based sensors are automatically recognized by the instrument and hold their calibration
- USB and communication saddle included
- Soft and hard-sided carrying cases available
- Flow cell available
- Cable weight available
- Belt clip available
- Tripod available
