Model 70
Low Cost Percent Oxygen Analyzer with Exceptional performance
The MODEL 70 is a Percent Oxygen Analyzer that is a perfect choice for accurately measuring in a NON- FLAMMABLE gas stream. The MODEL 70 is supplied in a compact, panel mount package and suitable for use in general purpose environments. The unique zirconium oxide sensor technology produces an incredibly accurate and stable reading over a wide O2 measurement and temperature range. The sensor has an unprecedented 10-year life expectancy, requiring only annual calibrations.

Features & Benefits
Full of standard features
The MODEL 70 Percent Oxygen Panel Mount Analyzer comes standard with advanced features, including 4-user selectable analog output ranges, dual independent alarms, comprehensive alarm logic (fail safe or non-fail safe, latching or non-latching and independent alarm delays), alarm bypass, and 3 levels of security settings. Automatic data logging provides detailed time-stamped records of O2 measurement, temperature, supply voltage and power brown-out history.
ZIRCONIUM OXIDE SENSOR TECHNOLOGY
AMI’s zirconium oxide sensors are extremely accurate and stable, have a 10-year life expectancy and are unaffected by barometric pressure fluctuations or rapidly changing temperatures from 0-120°F. Recommended calibrations are 1-2 times per year in the 0-25% oxygen range.
Exceptional Value
The MODEL 70 is the perfect choice for accurately measuring percent levels of oxygen in either inert background gases or enriched oxygen gas streams up to 95% O2. The MODEL 70 is a maintenance-free, compact analyzer loaded with advanced features at an exceptional price.
