Teledyne CLASS L-2C | C06689-L2C Micro-Fuel Cell Oxygen Sensor
Teledyne CLASS L-2C (P/N C06689-L2C) electrochemical oxygen sensor. Measures 0–100 ppm O₂ in inert gases, with 2-year life. For gas analyzers and safety monitors.
Product Overview
The Teledyne CLASS L-2C (Part Number C06689-L2C) is a micro-fuel cell electrochemical sensor designed for precise measurement of low-concentration oxygen in non-corrosive gas backgrounds. It provides a linear current output proportional to oxygen partial pressure, making it a core component in industrial gas analyzers, inert gas monitoring systems, and safety control panels. The sensor is maintenance-free and known for its long operational life.
