Teledyne CLASS I-17 | I-17 Micro-Fuel Cell Oxygen Sensor for Analyzers
Teledyne CLASS I-17 electrochemical micro-fuel cell oxygen sensor. Measures 0–100% O₂, used in portable & panel-mounted gas analyzers. 3-year life in air.
Product Overview
The Teledyne CLASS I-17 is a patented micro-fuel cell (MFC) electrochemical sensor designed for measuring oxygen concentration in gas analysis applications. It is a maintenance-free, disposable transducer that produces a current output directly proportional to the partial pressure of oxygen. This sensor is commonly used as the sensing element in Teledyne GB300 portable oxygen analyzers and other panel-mounted instruments for monitoring gas purity and safety.
