MW190
Bench Meter
2. GENERAL DESCRIPTION
Thank you for choosing Milwaukee Instruments. This instruction manual will provide you
the necessary information for correct use of the meter.
MW190
is is a logging microprocessor-based DO and Temperature bench meter.
Dissolved Oxygen is indicated in ppm (parts per million) or in %.
All measurements are automatically compensated for temperature. Salinity compensation
in water allows direct determination of Dissolved Oxygen in saline waters and altitude
compensation readjusts for the altitude variance.
The Dissolved Oxygen probe has a membrane covering the polarographic sensors and a
built-in thermistor for temperature measurements and compensation.
This permeable Teflon® membrane isolates the sensor elements from the testing solution,
but allows Oxygen to pass through. When a voltage is applied across the sensor, oxygen
that has passed through the membrane reacts causing a current flow, and hence
determining a reading.
