Operator Manual Data Sheet AMI Overview

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.
