  2. Thermistor - Wikipedia

    en.wikipedia.org/wiki/Thermistor

    NTC thermistors are widely used as inrush-current limiters and temperature sensors, while PTC thermistors are used as self-resetting overcurrent protectors and self-regulating heating elements. An operational temperature range of a thermistor is dependent on the probe type and is typically between −100 and 300 °C (−148 and 572 °F).

  3. Thermopile - Wikipedia

    en.wikipedia.org/wiki/Thermopile

    Thermopiles are used to provide an output in response to temperature as part of a temperature measuring device, such as the infrared thermometers widely used by medical professionals to measure body temperature, or in thermal accelerometers to measure the temperature profile inside the sealed cavity of the sensor. [4]

  4. Thermal immersion circulator - Wikipedia

    en.wikipedia.org/wiki/Thermal_immersion_circulator

    A thermal immersion circulator is an electrically powered device that circulates and heats a warm fluid kept at an accurate and stable temperature. [1] It is used in process, environmental, microbiological, hazardous waste, and other laboratories.

  5. Thermometric titration - Wikipedia

    en.wikipedia.org/wiki/Thermometric_titration

    Thermistors respond quickly to small changes in temperature such as temperature gradients in the mixed titration solution, and thus the signal can exhibit a small amount of noise. Prior to derivatization it is therefore necessary to digitally smooth (or "filter") the temperature curve in order to obtain sharp, symmetrical second derivative ...

  6. Thermometer - Wikipedia

    en.wikipedia.org/wiki/Thermometer

    Thermostats have used bimetallic strips but digital thermistors have since become popular. Alcohol thermometers , infrared thermometers , mercury-in-glass thermometers, recording thermometers , thermistors , and Six's thermometers (maximum-minimum thermometer) are used in meteorology and climatology in various levels of the atmosphere and oceans.

  7. Thermal cycler - Wikipedia

    en.wikipedia.org/wiki/Thermal_cycler

    The thermal cycler (also known as a thermocycler, PCR machine or DNA amplifier) is a laboratory apparatus most commonly used to amplify segments of DNA via the polymerase chain reaction (PCR). [1] Thermal cyclers may also be used in laboratories to facilitate other temperature-sensitive reactions, including restriction enzyme digestion or rapid ...

  8. Resistance thermometer - Wikipedia

    en.wikipedia.org/wiki/Resistance_thermometer

    Larger-diameter platinum wire is used, which drives up the cost and results in a lower resistance for the probe (typically 25.5 Ω). UPRTs have a wide temperature range (−200 °C to 1000 °C) and are approximately accurate to ±0.001 °C over the temperature range. UPRTs are only appropriate for laboratory use.

  9. Temperature data logger - Wikipedia

    en.wikipedia.org/wiki/Temperature_data_logger

    Autonomous data loggers can be taken to diverse locations that cannot easily support fixed temperature monitoring equipment. [3] These might include: mountains, deserts, jungles, mines, ice flows, caves, etc. Portable data loggers are also used in industry and laboratory situations where stand-alone recording is desired.
