About This Product

The S157CO2 analyzer can measure CO2 in the range 0-2,000ppm with 1ppm resolution. It can also be expanded to 0-1% CO2 with a single channel flow-through non-dispersive infrared CO2 analyzer. Ideal for measuring CO2 exchange in plants, insects, small animals, or organisms with low metabolic rates. It can also be used for measuring soil respiration and environmental monitoring. The S157 can be purchased as a standalone CO2 analyzer with integrated gas pump (S157-P) or with integrated gas pump and mass flow monitor (S157-PF). All versions of the S157 have rugged case temperature control, making them ideal for field use.
