| resistance thermometer n. A device measuring temperature by the change of the electrical resistance of a metal wire. |
thermometer [ther-mom´ĕ-ter]
an instrument for determining temperatures, in principle making use of a substance (such as alcohol or mercury) with a physical property that varies with temperature and is susceptible of measurement on some defined scale.
Temperatures on Celsius and Fahrenheit thermometers related to temperature ranges. From Elkin et al., 2000.
axilla thermometer a clinical thermometer that is placed in the axilla.
Celsius thermometer one that uses the Celsius scale.
centigrade thermometer one having the interval between two established reference points divided into 100 equal units, such as the Celsius thermometer.
clinical thermometer one used to determine the temperature of the human body.
electronic thermometer a clinical thermometer that uses a sensor based on thermistors, solid-state electronic devices whose electrical characteristics change with temperature. The reading is recorded within seconds, some having a red light or other device to indicate when maximum temperature is reached. Available models include hand-held, desk-top, and wall-mounted units, all having probes that are inserted orally or rectally.
Fahrenheit thermometer one that uses the Fahrenheit scale.
Kelvin thermometer one that uses the Kelvin scale.
oral thermometer a clinical thermometer whose mercury containing bulb is placed under the tongue.
recording thermometer a temperature-sensitive instrument by which the temperature to which it is exposed is continuously recorded.
rectal thermometer a clinical thermometer that is inserted in the rectum.
resistance thermometer one that uses the electric resistance of metals (thermocouple) to determine temperature.
self-registering thermometer
2. one that registers the maximum or minimum temperature attained in the measurement.
tympanic thermometer an electronic clinical thermometer that gives a digital reading in less than two seconds. Second-generation tympanic thermometers work by monitoring the temperature when the ear opening is sealed.
thermometer
an instrument for determining temperatures, in principle making use of a substance (such as alcohol or mercury) with a physical property that varies with temperature and is susceptible of measurement on some defined scale.
Celsius thermometer
one employing the Celsius scale, that is, with the ice point at 0 (0°C) and the normal boiling point of water at 100 degrees (100°C).
centigrade thermometer
one having the interval between two established reference points divided into 100 equal units, as the Celsius thermometer.
clinical thermometer
one used to determine the temperature of the patient in clinical situations.
electronic thermometer
a clinical thermometer using a sensor based on thermistors, solid-state electronic devices whose electrical characteristics change with temperature. The reading is recorded within seconds, some having a red light or other device to indicate when maximum temperature is reached. Available models include handheld, desk-top and wall-mounted units, all having probes that are inserted orally or rectally. It is expected that electronic thermometers worn by the patient will have some use.
Fahrenheit thermometer
one employing the Fahrenheit scale, that is, with the ice point at 32 and the normal boiling point of water at 212 degrees (212°F).
Kelvin thermometer
one employing the kelvin scale.
recording thermometer
a temperature-sensitive instrument by which the temperature to which it is exposed is continuously recorded.
rectal thermometer
a clinical thermometer that is inserted in the rectum for determining body temperature.
resistance thermometer
one that uses the electric resistance of metals for determining temperature (thermocouple).
self-registering thermometer
recording thermometer.
