Temperature Sensor Ranges
The stated accuracy of any temperature measurement device is for the “Recommended Temperature Range”
only. The narrow section of the temperature bar represents the widest range the sensor can be used in.
Accuracy in this range is not guaranteed. Probe damage may occur at the extreme ends of the temperature
range. Temperatures listed below are approximate.
