ProODO Optical Dissolved Oxygen Instrument overview：

user's manual

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 highlights of the ProODO Optical Dissolved Oxygen (DO) Instrument are as follows：

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
