DESCRIPTION The Model 309A Series Portable CO2 and O2 Analyzer is a rugged, fast-responding, and accurate instrument for conveniently monitoring the atmosphere in an apple storage C/A room. The standard range of the analyzer is 0-10% CO2 and 0-25% O2. Other ranges are available. The Model 309A series utilizes a single cell infrared detector for CO2 and a customer replaceable electrochemical sensor for O2. Neither sensor is affected by water vapor or other gas vapors in the sample gas. The O2 sensor typically lasts 3-4 years. In operation, a built-in sample pump draws in the gas sample...
