This CO2 analyzer may be used in a flow-through system configuration for instantaneous and continuous measurements of CO2 production or consumption. It can also be used in a closed system mode for measurements at extremely low activity levels.

This Q-S151 CO2 analyzer may be set up for use in the injection mode where small samples of CO2 gas are injected into a carrier gas flowing past the CO2 sensor for measurements of CO2 levels in the headspace of collected samples.

The Q-S151 is a key component of Qubit Systems’ carbon dioxide control system for regulating pCO2 in growth cabinet or rooms.
