Oxygen analyzer MODEL 111

portableelectrochemical

The AMI 111 series provide the ideal solution to percentage oxygen measurement in non-flammable gases. Most portable percent oxygen analyzers use replaceable electrochemical sensors, which suffer from drift, temperature and barometric pressure sensitivity, and require frequent replacement. This series of analyzers uses a non-depleting zirconium oxide sensor to measure. The sensor requires no support gases, and generates an almost perfectly stable reading with minimal drift for months or years. It is not significantly affected by temperature changes, or by barometric pressure changes. It will last for many years without being replaced. When you need an accurate oxygen measurement in an inert background, this series is unique. There are three versions of the model 111. The basic model expects a positive pressure of at least a few inches of water column, up to a maximum of 100psig. The 111P version contains a pump that draws the sample from a low pressure source, such as a glove box at atmospheric pressure or a line at a partial vacuum. It can draw from vacuums of up to 10”Hg.
