The Model 309 Series Portable CO2 and O2 Analyzer is a rugged, fast-responding, and accurate instrument for conveniently monitoring the atmosphere in a fruit storage C/A room. The standard range of the analyzer is 0-10% CO2 and 0-25% O2. Other ranges are available. The Model 309 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 2-3 years.In operation, a built in sample pump draws in the gas sample through the sample hose, filter/condensate trap, secondary filter and flow meter then on to the CO2 and 2 detectors. The gas readings are then displayed on LCD digital meters which have switchable backlights for use in dark areas.A rechargeable battery provides enough power for about 8 hours of continuous operation and the analyzer can be used while it is being recharged. A red LED tells when to recharge and a green LED verifies that it is receiving recharging power. The recharger is included.
