The TO2-1L PPM Oxygen Sensor provides high levels of accuracy, reliability and linearity throughout its measurement ranges. 

The sensor is capable of measuring oxygen from 0.01 parts-per-million up to 25.0%.  For maximum life and performance, we recommend to use it when monitoring oxygen < 1000 ppm.

Southland Sensing Ltd.'s direct fit replacement electrochemical galvanic "micro fuel cell" oxygen sensors are known for their quality, performance and exceptional value. 

Southland Sensing Ltd. designs and manufactures oxygen sensors that have the same principle of operation as disclosed in US Patent Nos. 3,429,796 and 3,767,552. 

The oxygen sensors operate under the same principles as those currently being marketed by other manufacturers. 

Varying performance advantages to the SSO2 sensors can be attributed to minor modifications in dimensions, connections, and packaging. However, the principle of operation and the basic components remain the same.
