Bridge Analyzers offers two oxygen sensors for MAP Analyzer applications. The sensors are field changeable, mechanically and electrically interchangeable, and self-calibrating; aiding field configuration of any Bridge MAP Analyzer to any application.
The p/n 001140 (Green band) sensor is used to measure either residual oxygen or high oxygen (Hi-Ox) in gas mixes containing less than 20% CO2. It is identified with a Green stripe.
The p/n 001057 (Blue band) sensor is used where there is above 20% CO2 in the package headspace, and for all oxygen levels – usually residual Oxygen in high CO2 headspace gases (Lo-Ox).
See the table below for a comparison of the sensors:
