Q-S151 CO₂ Analyzer 0-2000ppm

Q-S151 Infrared CO₂ Analyzer is a Non-Dispersive Infrared CO₂ Analyzer that measures CO₂ in 0 to 2000ppm range with 1ppm Resolution. Dependable Technology, Rugged and Modular for easy fit in our Q-Box Packages or for standalone use. Q-S151 is ideal for CO₂ Exchange Measurements with Leaves, Insects, Small Animals or Organisms with a Low Metabolic Rate. It is also excellent for measuring Soil Respiratory activity in-situ in the field and in the lab.

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 System's Carbon Dioxide Control System for regulating pCO₂ in growth cabinet or rooms. Contact us for more information on these systems.
