Q-S153 CO2 Analyzer (0-10%)


Q-S153 CO2 Analyzer is a single channel non-dispersive infrared CO2 analyzer which measures CO2 in 0 to 5% an 0 to 10% range with 0.01% resolution.   Q-S153 replaces our S153 CO2 Analyzer.  The same dependable technology has been improved, made more rugged and modular for easy fit in our NEW Q-Box Packages. Q-S153 CO2 analyzer is ideal for CO2 exchange measurements in larger or more active animals and in situations where high CO2 fluxes may occur, such as fermentation processes, human respirometry. Q-S153 may be used in a flow-through gas exchange configuration for instantaneous and continuous measurements of CO2 exchange or as part of Qubit Systems’ carbon dioxide control system for regulating pCO2 in growth cabinets and rooms.
