S157 CO2 Analyzer 0-2000ppm

S157 CO2 Analyzer is a single channel flow-through non-dispersive infrared CO2 analyzer that measures CO2 in the 0 to 2000 ppm range with 1 ppm resolution. The range can be extended to 0 – 1% CO2, if requested. The CO2 Analyzer is ideal for CO2 exchange measurements with leaves, insects, small animals or organisms with a low metabolic rate.
