MODEL 111 Percent Oxygen Analyzer Description：

Operator Manual Data Sheet AMI Overview

Features & Benefits

IDEAL FOR NON-FLAMMABLE GASES

The MODEL 111 Portable Percent Oxygen Analyzer can handle non-flammable samples and is available in 3 configurations: base model, sample pump model and sample pump model for hazardous areas. The Analyzer is used in many applications, including those used for nitrogen purity, inert gas blanketing and oxygen purity.

ZIRCONIUM OXIDE SENSOR TECHNOLOGY

AMI’s zirconium oxide sensors are an extremely stable, have a very long service life, and are not affected by barometric or temperature changes. They are an excellent option for measuring percent levels of oxygen in inert atmospheres, such as the amount of oxygen in the air of an enclosed space. Additionally, these sensors last for many years and require minimal calibration.

FULL OF STANDARD FEATURES

The MODEL 111 Portable Percent Oxygen Analyzer can connect with the COMMAND CENTER software to access advanced features, including automatic data logging that provides detailed time-stamped records of O2 measurement, temperature, supply voltage and power brown-out history.

TRULY PORTABLE AND DESIGNED FOR THE FIELD

Starting at 5 lbs (7.3 kg), the MODEL 111 is the smallest, lightest, fastest and most accurate portable Percent Oxygen Analyzer in the industry.
