Oxygen Measurement Amplifier
Part #: O2100C

The O2100C is a paramagnetic-based oxygen measurement module designed to provide accurate measurement of the oxygen content in ambient air, expired breath, and in breathing gas mixtures. The paramagnetic technology is non-depleting, which means there are no consumable parts and ensures consistent performance over time.

The module provides a selectable range of analog outputs that map voltages to 0-100% oxygen concentration levels. The module is a lightweight, rugged unit that offers a number of advanced features, such as fast response and user-adjustable sampling flow rate.

Sampling line connections for input and output flow are readily accessible on the front panel of the module.

  • The O2100C module interfaces (via the AFT20 gas sampling interface kit) with the AFT15A and AFT15B mixing chambers, the AFT21 and AFT22 non-rebreathing T valves, or the AFT25 mask with integral non-rebreathing T valve.

The excellent linearity of the O2100C makes it possible to calibrate the module by checking two optimally separated points in the desired measurement range.

This fast-response analyzer is ideal for monitoring time-averaged O2 levels using mixing chambers or real-time O2 levels for breath-by-breath measurements.

The selectivity of the paramagnetic measurement for oxygen means there is no interference from other respiratory gases. The O2100C small volume chamber allows a rapid gas exchange, giving the capability for fast response oxygen measurement.

The O2100C offers a stable and inherently linear measurement of oxygen.

The O2100C uses Servomex, Inc. technology for O2 concentration signal processing.
