The TO2-238 PPM Oxygen Sensor provides high levels of accuracy, reliability, and linearity throughout its measurement range.
The sensor is capable of measuring oxygen from 0.01 parts-per-million up to 25.0%. For maximum life and performance, it is recommended for applications where oxygen levels are below 1000 ppm.
The TO2-238 series oxygen sensor is designed for use in acid gas streams such as CO₂ or natural gas background gas environments.
It is also suitable for natural gas applications where H₂S gas is up to 500 ppm.
Southland Sensing Ltd.'s direct-fit replacement electrochemical galvanic "micro fuel cell" oxygen sensors are known for quality, performance, and value.
These sensors operate under principles similar to those disclosed in US Patent Nos. 3,429,796 and 3,767,552.
While minor modifications in dimensions, connections, and packaging may vary performance characteristics, the core operating principle remains the same across comparable sensors.
