S158 CO2 Analyzer (0-10%)

Qubit

S158 CO2 Analyzer is a single channel non-dispersive infrared CO2 analyzer that measures CO2 in 0 to 10% range with better than 0.01% accuracy.  It 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. The S158 shares the same infrared technology and modular design as the S157 CO2 Analyzer. The analyzer may be used in a flow-through gas exchange configuration for instantaneous and continuous measurements of CO2 exchange. It can also be used in stop flow or closed system modes. The S158 may also be used as part of Qubit Systems’ carbon dioxide control system for regulating pCO2 in growth cabinet.  We recommend using S158 with our C950 Gas Exchange Software or other data acquisitions software.
