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.

Key Feature​

CO₂-tolerant design, maintenance-free

Key Features

  • CO₂ Resistant:​ Specifically formulated for accurate O₂ measurement in flue gases and other streams containing 0–100% carbon dioxide.

  • Maintenance-Free:​ Sealed, disposable design with no electrolyte refilling required.

  • True Zero:​ Generates zero current in the absence of oxygen; requires no zero gas.

  • Flow Insensitive:​ Diffusion-based operation is unaffected by sample flow rate variations.

Applications

  • Combustion flue gas analysis (boilers, furnaces, heaters)

  • Process gas monitoring in CO₂-rich environments

  • Industrial safety and oxygen deficiency monitors in confined spaces

  • Replacement cell for Teledyne 3000/300 series analyzers
