In general, oxygen sensors need to be replaced at different rates based on their usage and their technology. Some systems, like a
TDL O2 sensor, are capital investments that don’t require replacement for many years. Others, like
polarographic and
optical O2 sensors, need to have select consumables replaced on a regular basis to ensure accurate operation. METTLER TOLEDO O2 sensors with
Intelligent Sensor Management (ISM) technology provide predictive diagnostics, including a Dynamic Lifetime Indicator, that help you plan for maintenance and replacement of your oxygen sensor.
