#thermometer  measuring instrument for measuring temperature
  supertype:  measuring_instrument__measuringinstrument__measuring_system__measuringsystem__measuring_device__measuringdevice  instrument that shows the extent or amount or quantity or degree of something
  part:  capillary_tubing
  subtype:  alcohol_thermometer__alcoholthermometer__alcohol-in-glass_thermometer  thermometer consisting of a glass capillary tube marked with degrees Celsius or Fahrenheit and containing alcohol which rises or falls as it expands or contracts with changes in temperature
  subtype:  candy_thermometer__candythermometer  a thermometer used to determine the temperature of candy syrups during cooking
  subtype:  Centigrade_thermometer  a thermometer calibrated in degrees centigrade
  subtype:  cryometer  a thermometer designed to measure low temperatures
  subtype:  dry-bulb_thermometer  an ordinary thermometer with a dry bulb; used to measure the air temperature
  subtype:  Fahrenheit_thermometer  a thermometer calibrated in degrees Fahrenheit
  subtype:  gas_thermometer__air_thermometer__airthermometer  thermometer that measures temperature by changes in the pressure of a gas kept at constant volume
  subtype:  maximum_and_minimum_thermometer  thermometer that records the highest and lowest temperatures reached during a period of time
  subtype:  meat_thermometer  a thermometer that is inserted into the center of a roast (with the top away from the heat source); used to measure how well done the meat is
  subtype:  mercury_thermometer__mercurythermometer__mercury-in-glass_thermometer  thermometer consisting of mercury contained in a bulb at the bottom of a graduated sealed glass capillary tube marked in degrees Celsius or Fahrenheit; mercury expands with a rise in temperature causing a thin thread of mercury to rise in the tube
     subtype:  Beckman_thermometer  a mercury thermometer that measures small differences or changes in temperature
     subtype:  mercury-in-glass_clinical_thermometer__clinical_thermometer  a mercury thermometer designed to measure the temperature of the human body; graduated to cover a range a few degrees on either side of the normal body temperature
  subtype:  oven_thermometer  a thermometer that registers the temperature inside an oven
  subtype:  pyrometer  a thermometer designed to measure high temperatures
     subtype:  optical_pyrometer__opticalpyrometer__pyroscope  a pyrometer that uses the color of the light emitted by a hot object
     subtype:  pyrometric_cone  a pyrometer consisting of a series of cones that melt at different temperatures
     subtype:  radiation_pyrometer__radiationpyrometer  a pyrometer for estimating the temperature of distant sources of heat; radiation is focussed on a thermojunction connected in circuit with a galvanometer
     subtype:  resistance_pyrometer  pyrometer that measures high temperatures by the resistance in a heated wire
  subtype:  Reaumur_thermometer  an alcohol thermometer calibrated in degrees Reaumur
  subtype:  resistance_thermometer__platinum_thermometer  thermometer that measures temperature by changes in the resistance of a spiral of platinum wire
  subtype:  reversing_thermometer__reversingthermometer  a thermometer that registers the temperature in deep waters
  subtype:  self-registering_thermometer  a thermometer that records the temperature automatically
  subtype:  telethermometer  a thermometer that registers the temperature at some distant point
  subtype:  thermocouple_junction__thermocouple  a kind of thermometer consisting of two wires of different metals that are joined at both ends; one junction is at the temperature to be measured and the other is held at a fixed lower temperature; the current generated in the circuit is proportional to the temperature difference
  subtype:  thermoelectric_thermometer__thermel__electricthermometer  a thermometer that uses thermoelectric current to measure temperature
  subtype:  thermometrograph__thermograph  a thermometer that records temperature variations on a graph as a function of time
  subtype:  thermopile  a kind of thermometer for measuring heat radiation; consists of several thermocouple junctions in series
  subtype:  wet-bulb_thermometer  a thermometer with a bulb that is covered with moist muslin; used in a psychrometer to measure humidity
