S157 CO₂ Analyzer 0-2000ppm

The S157 CO₂ Analyzer is a Single Channel Non-Dispersive Infrared CO₂ Analyzer that measures CO₂ in 0 to 2000ppm range with 1ppm 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 Flowmonitor (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 System's 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.
