The TO2-19 Hybrid PPM Oxygen Sensor delivers high accuracy, reliability, and linearity across its full measurement range.
The sensor is capable of measuring oxygen from 45 parts-per-million (ppm) up to 25.0%. A unique feature of this sensor is its ability to be exposed to ambient air when not in use while still maintaining a fast and accurate response down to low ppm levels. This makes it ideal for applications such as 3D metal printing and welding.
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.
✔ Hybrid ppm + percent oxygen measurement
✔ Fast response even after ambient air exposure
✔ Ideal for welding and 3D metal printing applications
