During operation, the SSI oxygen probe may experience malfunctions. Common troubleshooting methods include:

Reference Air Test: Verify the normal supply of reference air. If the millivolt signal drops rapidly after the reference air is cut off, it may be necessary to replace the probe, perform regular carbon burn operations to clear carbon deposits on the probe surface, ensuring measurement accuracy. If the fault cannot be resolved independently, please contact our technical staff for assistance. The SSI oxygen probe is designed and manufactured in the USA and is the standard product for atmosphere heat treatment in North America. In China, several companies act as agents for sales, offering various models and specifications of oxygen probes.
