The TO2-233 PPM Oxygen Sensor delivers high accuracy, reliability, and linearity across its full measurement range.
The sensor is capable of measuring oxygen from 0.01 parts-per-million (ppm) up to 25.0%. For maximum life and performance, it is recommended for use in applications where oxygen levels are below 1000 ppm.
This TO2-233 series oxygen sensor is designed for use in acid gas streams such as CO₂ or natural gas background gas.
Southland Sensing Ltd.'s direct-fit replacement electrochemical galvanic "micro fuel cell" oxygen sensors are recognized for their quality, performance, and exceptional value.
These sensors operate using the same electrochemical principles disclosed in US Patent Nos. 3,429,796 and 3,767,552 and follow the same operating concepts used by other manufacturers in the industry.
✔ Trace ppm oxygen measurement capability
✔ Optimized for acid gas environments (CO₂ / natural gas)
✔ High accuracy and stability
✔ Micro fuel cell electrochemical technology
✔ Backed by our 12-month warranty
