NTC Thermistor Probes
Thermistor probes are accurate probes which exhibit a change in resistance with a change of temperature. Thermistor probes have a negative temperature coefficient (NTC), the resistance decreases with the increase in temperature. Thermistor probes cover a limited temperature range and are generally slower to respond to changes in temperature than thermocouples but quicker than PT100 probes. Thermistor probes tend to be smaller than PT100 probes but larger than thermocouple probes. Thermistor probes are not recommended for the measurement of surface temperatures.
