The Model 309A Series Portable CO2 and O2 Analyzer is a rugged, fast-responding, and accurate instrument for conveniently monitoring the controlled atmospheres in food storage rooms. The standard range of the analyzer is 0-10% CO2 and 0-25% O2. 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. Themore CO2 detector is not consumed during use.
In operation, a built-in sample pump draws in the gas sample through the sample hose, filters, and flow meter, then on to the CO2 and O2 detectors. You can walk around with the instrument or run tubing to it from the C/A room. The gas readings are displayed on a bright touch-screen display.
A rechargeable lithium ion battery provides enough power for about 8 hours of continuous operation and the analyzer can be used while it is being recharged. The 309K series case is small but rugged and dust & water resistant when closed. Stack temperature measurement and built-in printer that also shows date & time are optionally available on any model. less
