There are several varieties of oxygen (O₂) sensors used in ENMET instruments. They are generally not interchangeable and instruments were designed to specifically handle the output characteristics of the only the original sensors.

Some instruments may have been modified to accommodate a different version sensor. If you are unsure as to the particular sensor in your instrument, please contact ENMET Customer Service or your local distributor. Be sure to have the model number and serial number of your instrument before calling.
