Operation:

The thermistor is a small, ceramic-encapsulated metal-oxide semiconductor. It exhibits a characteristic non-linear inverse relationship between resistance and temperature that allows its use as a temperature sensor. The relatively large change in resistance as a function of temperature (~ 4%/°C) gives a signal response far greater than thermocouples and resistance temperature devices (RTD). The probe is held under the nostrils to measure the temperature of exhaled breath. It can be cold sterilized between subjects.

Application:

The Nasal Temperature Probe is ideal for measuring nasal air temperature as an indicator of respiration. It is well suited to applications such as biomedical temperature monitoring requiring repeatability, high sensitivity and rapid response.
