The Model 103 Thermistor uses a negative temperature coefficient (NTC) thermistor housed in a durable stainless steel shaft to provide quick and accurate temperature readings.
Applications: Temperature, Thermistor Theory, Heat of Neutralization
Features: Accurate, Small Thermal Mass, Fast Response
The Thermistor Temperature Probe, like all NTC thermistors, decreases in resistance as temperature increases. The microLAB Interface measures this resistance by applying a precisely measured voltage, accurately measuring the returned current, and applying Ohm’s Law (R = V/I) to calculate resistance. One can, if desired, use the formula tool to calculate and display this resistance to explore the temperature/resistance response of the sensor.
microLAB software utilizes the Steinhart-Hart equation to calculate the temperature of the thermistor, a technique used throughout industry and in research labs. Since the Steinhart-Hart relationship is non-linear, the effective resolution of the temperature measurement increases with increasing temperature. At 0°C, the resolution is 0.01 °C, at 20 °C it is 0.006 °C, and at 70 °C it is 0.001°C.
