EcoSense® ODO200M Optical DO/Temperature

Accurate, economical, handheld dissolved oxygen
instrument with optical sensor technology

The YSI EcoSense® instruments provide accurate data in the
most affordable package. The "M" stands for memory and the
instruments feature a real-time clock, larger memory and simple
data transfer to a PC with a built-in USB port.

The ODO200M's optical sensor is easy-to-use and provides
accurate data without the hassle of membrane changes and
frequent calibrations.

Parameters:

Dissolved Oxygen (optical)
% and mg/L
Temperature
°C

Optical benefits include:

• no stirring required

• no warm-up time

• no electrolyte solution

• no electrode maintenance

• no membranes

• no interference from gases
such as hydrogen sulfide

• less frequent calibration

The ODO200M simultaneously measures dissolved oxygen and
temperature with the following features:

• Rugged, waterproof, field-worth case. IP-67 rated.

• Durable field probe and cables made in the USA. 1-, 4- and
10-meter cables available.

• Waterproof micro-USB port for transferring data to PC; no
software required.

• Holds 250 data sets; no need to write down data.

• Real-time clock for date/time stamp of saved data.

• User-selectable re-calibration prompt provides reminder to
calibrate.

• Automatic temperature compensation; manual input for salinity
and barometric pressure compensation.

• 1-year warranty on instrument, probe/cable and sensor cap.

• Replaceable optical sensor cap with 1-year warranty (12-18
month expected life).

The ODO200M is designed for quick, accurate measurements at an
affordable price. The maintenance-free optical dissolved oxygen
sensor and easy-to-use handheld make the ODO200M ideal for
many applications.
