Thermometers - Essential Temperature Measurement Devices
Thermometers FAQ
What does a thermometer do?
They write new content and verify and edit content received from contributors. thermometer, instrument for measuring the temperature of a system. Temperature measurement is important to a wide range of activities, including manufacturing, scientific research, and medical practice.
Can a thermometer be used to measure temperature?
A thermometer is an instrument to measure temperature (see Temperature and Temperature Measurement, Practice ). Temperature cannot be measured directly (for instance, as a length is measured by its segment). Only the measurement of another physical property being a function of temperature may provide temperature determination.
What is a gas thermometer?
A gas thermometer is a primary instrument for determination of thermodynamic temperature. Application of exact relations requires design of complicated devices inconvenient for practical use.
How do thermometers measure temperature?
Thermometers measure temperature by utilizing the principle of thermal expansion. Various types of thermometers exist, including liquid-in-glass, bimetallic strip, thermocouple, and resistance temperature detectors. The working mechanism of a thermometer involves the use of a thermometric property and a thermometric substance.
How does a digital thermometer measure body temperature?
Digital thermometers use a thermistor, a resistor with a resistance that varies with temperature. To measure body temperature, infrared thermometers that focus infrared light onto a detector that measures the amount of light received and convert the electrical signal produced by the detector into a temperature were also used.
What is a laboratory thermometer used for?
A laboratory thermometer, which is colloquially known as the lab thermometer, is used for measuring temperatures other than the human body temperature. It ranges from -10˚C to 110˚C. Checking the temperature of other substances. Checking the temperature of a solvent but not a clinical one.
