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 through the sample hose, filter/ condensate trap,
secondary filter and flow meter then on to the CO2 and O2 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.
