Teledyne CLASS A-5 | C06689-A5 Micro-Fuel Cell %O2 Sensor for CO2 Backgrounds

Teledyne CLASS A-5 | C06689-A5 Micro-Fuel Cell %O2 Sensor for CO2 Backgrounds

Teledyne CLASS A-5 (P/N C06689-A5) electrochemical oxygen sensor. Measures 0–25% O₂ in 0–100% CO2 gas streams, 45s response, for flue gas and combustion analysis.

Product Overview

The Teledyne CLASS A-5​ (Part Number C06689-A5) is a micro-fuel cell (MFC) oxygen sensor​ specifically designed for percent-level oxygen measurement in gas streams containing high concentrations of carbon dioxide (CO₂). It is the standard replacement cell for combustion flue gas analyzers, boiler efficiency monitors, and process gas systems​ where acid gas resistance and stable performance in CO₂-rich environments are critical.
