The AMI model 65 is the ideal solution for measuring oxygen in non-flammable gases in a general purpose environment. In a very small size, and at very low cost, it provides a basic electronic package with a single range voltage output (isolated current output optional) 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 65 suffers from none of these issues. It has been tested over a temperature range of 0°F to 130°F. Its sensor is unaffected by flow rate changes over the range of 0.1 to 5 SCFH. The model 65 is designed for integration into a user’s system as a stand-alone oxygen sensor. In standard form, it provides a voltage output of 0-2.5V corresponding to 0-25% oxygen, while requiring only about 3 watts of power. A built-in microprocessor controls the sensor heater and automatically linearizes the sensor output. Since the sensor is non-depleting the unit may be stored indefinitely in a power off state without worrying about sensor life issues. In many cases it may be used with no calibration required over its entire life. Since the unit is not flow rate dependent a simple sample system is normally adequate, or it may be specified with a diffusion screen for ambient applications.
