Oxygen analyzer MODEL 70

electrochemical

The AMI model 70R1 is the ideal solution for measuring oxygen in non-flammable gases in a general purpose environment. In a very small size, and at low cost, it provides a complete electronic package with a full set of features together with a zirconium oxide sensor that has an expected ten year life, with virtually no calibration required. Traditional electrochemical oxygen analyzers suffer from poor stability, requiring monthly calibration and frequent sensor replacement, and they suffer from sensitivity to both temperature changes and barometric pressure changes. Their reading can change by as much as 10% when a weather change occurs. The AMI model 70R1 suffers from none of these issues. It has been tested over a temperature range of 0°F to 120°F. Its sensor is unaffected by flow rate changes over the range of 0.1 to 5 SCFH, and as a result AMI is able to use an orifice to control the flow. The analyzer is built around a modified version of the same electronic architecture used in most of AMI’s advanced analyzers. Two microprocessors working together provide a vast amount of functionality, with the industry’s most intuitive front panel controls married to the most complete PC user interface. For advanced users, ModBus RTU over RS-485 is also provided as standard.
