“wet” oxygen measurement. The definition of oxygen measurement on a “dry” basis is based on the assumption that the moisture content in a flue stream is removed before the oxygen content is measured. Portable oxygen analyzers provide a “dry” oxygen measurement. There will be a difference in the two methods of measuring oxygen.
Oxygen measurement in the percentage range to trace measurement in the range of ppm and ppb can be achieved within a second without disadvantages to the sensory installation. Oxygen meter GSM-touch The hand-held Oxygen Meter GSM-touch is a state-of-the art measuring instrument controlled by a touch pad. Oxygen diffuses through the membrane and is reduced at the cathode by the voltage. This process produces a current flow, which is detected by the meter and is proportional to the partial pressure of oxygen. Since oxygen is 'consumed' the sample needs to be stirred to ensure accurate readings. Gas-phase oxygen electrode systems allow the measurement of oxygen evolution or uptake within a sealed sample chamber. The sample chamber is designed to accommodate 10cm 2 leaf discs which are cut using a special leaf disc cutter. However, any sample type such as root sections, lichens, mosses, conifer needles or small seeds may be used.

Oxygen meter GSM-touch
The hand-held Oxygen Meter GSM-touch is a state-of-the art measuring instrument controlled by a touch pad.
This oxygen meter is integrated in an elegant aluminium housing. The display's 24mm character height makes it very easy to read the measurements.
A graphical display with freely programable axes continually shows the current value and the selected history.
The measured values can be saved onto a flash drive through the oxygen meter‘s USB interface or sent on via Ethernet.
Parameterising outputs, alarms and histogram on the touch pad is easy and self-explanatory.
