The S157 CO2 Analyzer is a single channel non-dispersive infrared CO2 analyzer that measures CO2 in 0 to 2000 ppm range with 1 ppm resolution. This CO2 Analyzer is ideal for CO2 exchange measurements with leaves, insects, small animals or organisms with a low metabolic rate or for environmental monitoring.
The S157 CO2 analyzer can be used in monitoring of greenhouse and growth chamber CO2 levels. It is rugged and portable for use in the lab or field (with optional battery pack). The analyzer may be used in a flow-through gas exchange configuration for instantaneous and continuous measurements of CO2 exchange. It can also be used in an injection mode with an injection septum for measurements of CO2 levels in gas samples collected earlier. For measurements of extremely small changes in CO2 levels the analyzer can be used in stop flow or closed system modes. The S157 CO2 Analyzer can be purchased with a built in gas pump (S157-P) or with a built in gas pump and flow monitor (S157-FP). The S157 CO2 Analyzer shares the same infrared technology as the S158 CO2 Analyzer. It can also be used as part of Qubit Systems’ CO2 Control System for regulating pCO2 in growth cabinets or other chambers. We recommend using S157 with C901 Logger Pro software. Other data acquisitions software can also be used.
