Dissolved Oxygen Meter
The TecPen Dissolved Oxygen Meter provides accurate oxygen measurement in mg/L or parts per billion (ppb) in water and other liquids. This portable, rechargeable DO meter is useful for measuring trace oxygen levels from 0-2,000 ppb for quality control in packaged liquids like beer, or for biological or industrial applications.
The meter is designed to be used in a process with pressurized liquid from a sampling valve, or with an external pump having 1 L/min. flow. Because it relies on fluid pressure instead of an internal pump, it can monitor trace oxygen levels in real-time for hours before recharging.
Unlike electrochemical sensors, this optical oxygen sensor is not affected by other gases including nitrogen or CO2, Because there are no moving parts it requires virtually no maintenance. Measurement are taken in seconds and data can be logged in internal memory and downloaded later via USB.
