2. INSTRUMENT OVERVIEW

MW605

is a portable, IP67 rated meter designed for fresh and

saltwater measurements of dissolved oxygen (DO).
The

MW605

meter is compatible with

MA860

galvanic DO probe.

Galvanic probes require no conditioning and thus the instrument

is ready to measure when it is powered on.
Concentration measurements are automatically compensated for

temperature and salinity.
Temperature is automatically measured (in both degree Celsius

and Fahrenheit) and compensated.
Salinity and altitude can be configured in Setup.
Other features include:

y

Easy to read LCD display

y

Auto-off feature to prolong battery life

y

One or two % saturation calibration points at 100% (water

saturated air) and 0% (zero oxygen solution)

y

Dedicated GLP key to store and recall data on system status

y

Available log space for up to 1000 records

y

Logged data can be exported using a USB cable
