Teledyne CLASS B-2C | C06689-B2C Micro-Fuel Cell Trace Oxygen Sensor

Teledyne CLASS B-2C | C06689-B2C Micro-Fuel Cell Trace Oxygen Sensor

Teledyne CLASS B-2C (P/N C06689-B2C) electrochemical micro-fuel cell. Measures 0–100 ppm O₂ in H₂/He/inert backgrounds, 18–24 month life for gas purity analyzers.

Product Overview

The Teledyne CLASS B-2C​ (Part Number C06689-B2C) is a trace oxygen sensor​ based on micro-fuel cell technology. It is engineered for high sensitivity in hydrogen, helium, and inert gas applications​ where CO₂ is absent. This sensor is a direct-fit component for analyzers requiring precise ppm-level monitoring in semiconductor manufacturing, inert gas blanketing, and gas purity verification.
