LFO2-AH Lead-Free Oxygen Sensor

O2 Gas Sensor, Amperometric Lead-Free, A-Series, 5Y+ Life

The LFO2-AH O2 sensor is optimized for low oxygen detection (0-2%), providing precision and reliability for controlled or inert environments where low-level oxygen monitoring is critical. The LFO2-AH has a very low and stable baseline for accurate measurements as low as hundreds of ppm.
