Q-S151 Infrared CO2 Analyzer is a non-dispersive infrared CO2 analyzer that measures CO2 in 0 to 2000 ppm range with 1 ppm resolution. Dependable technology rugged and modular for easy fit in our Q-Box Packages or for stand alone 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 Systems’ carbon dioxide control system for regulating pCO2 in growth cabinet or rooms. Contact Qubit for more information on these systems.

I have tried several very cheap CO2 meters but yours is by far the best. Very quick response and reproducible. Measures respiration rate for compost incubated for just an hour. but i leave it for 24h unless it is very unstable. Other meters are so slow they do not really work the way i need.Testimonial
