Gas Analysers
Digital gas flow analyser for connection to fermenters or as stand-alone laboratory instruments: LAMBDA OXYMETER, CARBOMETER & METHAMETER
LAMBDA OXYMETER
The gas flow analyser LAMBDA OXYMETER is a flow-through optical oxygen meter for applications where the Oxygen concentration in the gas flow needs to be determined. The LAMBDA OXYMETER is designed for the Minifor2Bio fermentation system, however, the laboratory measurement instrument can also be used separately as a stand-alone instrument.
LAMBDA OXYMETER uses a factory-calibrated Oxygen sensor which measures ambient oxygen levels using the principle of fluorescence quenching by oxygen, also known as luminescence quenching.
The luminescence quenching principle measures the partial pressure of oxygen (ppO2. The internal barometric pressure sensor measurement along with ppO2 measurement allows the oxygen concentration (O2%) value to be calculated.
The in-built sensor benefits from a low-power operation, traditionally associated with electrochemical and galvanic sensors, while providing a much longer lifetime due to the non-depleting sensing principle.
