OUR MEASUREMENT

16. OUR MEASUREMENT

The

OUR is used to determine the oxygen consumption or respiration rate in water. It is defined as the

mg/L of oxygen consumed per hour.
The following equation is used for

OUR determination:

where:

DO

START

=

Dissolved oxygen level at start of test

DO

END

=

Dissolved oxygen level at end of test

t

ELAPSED

=

Elapsed time of test in seconds

total volume/sample volume = Dilution factor of sample
Before starting an OUR test remember to set the OUR configuration from the

Setup

menu.

This a an example of possible setting. Follow your normal SOP.

Make sure the

DO

probe has been calibrated before using. Clean off probe between samples.

Press

MODE

to select the

OUR measurement mode. Place the calibrated probe into the airtight

container of sample. Stir the sample. Press

Start

to begin taking measurements.

During the analysis the meter will display the ongoing calculation.
