Measurement of oxygen, particularly dissolved
oxygen, is a common parameter in environmental analysis. Equipment for oxygen analysis and
measurement includes DO analyzers, CO
2 and O
2 meters, benchtop DO
monitors, and portable dissolved oxygen meters for use with both fresh and saltwater that
can achieve 0.01 mg/L precision.
Systems optimized for use with glassware and
disposables, for use in the brewing and beverage industry, and in industrial process control
are available.
These may include noninvasive oxygen sensors that measure the
partial pressure of dissolved and gaseous oxygen, oxygen transmitters, and systems for
noninvasive on-line culture monitoring of oxygen and pH.
What to Consider When Choosing Instruments for Oxygen Analysis
?
Take note of temperature range, resolution, response time, accuracy, and limit of detection
when comparing dissolved oxygen measurement devices.
