The measurement accuracy of the SSI oxygen probe varies with temperature changes. According to the information I found, zirconia oxygen probe measurement accuracy is good within a specific temperature range, but its performance is affected by temperature control. For example, when temperature control is unstable or inaccurate, it can affect the migration rate of oxygen ions and the generation of concentration potential difference, leading to measurement errors. Additionally, the operating temperature range of the SSI oxygen probe is typically 700°C to 1100°C (1291-112°F to 2012°F), within which the probe's measurement accuracy is usually ±0.1mV (related to the accuracy of the detection instrument). However, if the temperature exceeds the recommended range, the probe's measurement accuracy may decrease.
