NTC thermistor measurements must note the following:
• can not be measured in the air, the larger the difference in air temperature measurement inaccurate, resulting accuracy deviation.
• After using the high-precision measurements of the bath, measured after NTC into the bath, the bath temperature must be stable before measurement.
• Measure the voltage as low as possible in order to reduce measurement errors due to self-heating NTC.
• High temperature measurement, required temperature bath thermometer correction, check

VIII Thermistor
Thermistors are a type of resistor that acts as a temperature-sensing element, generally made of ceramic or polymer. Thermistors exhibit a large change in resistance proportional to a small change in temperature.
Thermistors come in two common types:
NTC (Negative Temperature Coefficient) thermistors In these thermistors resistance decreases as temperature rises. An NTC is commonly used as a temperature sensor, or in series with a circuit as an inrush current limiter.
PTC (Positive Temperature Coefficient) thermistors â?? In these thermistors resistance increases as temperature rises. PTC thermistors are commonly installed in series with a circuit, and used to protect against overcurrent conditions, as resettable fuses.
