Digital thermometers are temperature-sensing instruments that are easily portable, have permanent probes, and a convenient digital display. The way a digital thermometer works depends upon its type of sensor. Sensor types include resistance temperature detector (RTD), thermocouple and thermistor.
Correspondingly, what are 3 types of thermometers?
What Are the Different Ways a Thermometer Can Be Used?
- Axillary Thermometers (under your arm)
- Oral Thermometers (under your tongue)
- Tympanic Thermometers (in your ear)
- Rectal Thermometers (in your rectum)
- Temporal Artery or Infrared Thermometers (across your forehead)
Thereof, what are the parts of a thermometer?
The main parts of a mercury thermometer are the capillary, the bulb, the scale, and the expansion chamber.
- Spherical Bulb. The bulb is the lowest part of the thermometer, which has a spherical shape. …
- Capillary Tube. …
- Expansion Chamber. …
- Scale Lines. …
- Safety Precautions.
What are the uses of digital thermometer?
The most commonly used thermometer in the home is the digital thermometer. Digital thermometers can be used to record temperatures from the mouth, armpit or rectum. Armpit temperatures are the least accurate. Rectal temperatures provide the most accurate readings for children between 3 months and 3 years of age.
What is digital thermometer short answer?
The Digital Thermometer is a battery-operated thermometer with connected measuring sensor and easy to read LCD display.It generates great accurate temperature readings.It is made of durable plastic materials and suitable for all kinds of refrigerant equipments such as refrigerant cabinet, display cabinet and so on.
What is the importance of thermometer?
A thermometer is an instrument that measures temperature. It can measure the temperature of a solid such as food, a liquid such as water, or a gas such as air. The three most common units of measurement for temperature are Celsius, Fahrenheit, and kelvin.
What is the principle of digital thermometer?
Digital thermometers contain a small computing mechanism and a resistor. A change in temperature causes the sensor to notice a change in resistance. The computer converts the difference in resistance into a difference in temperature and offers a digital readout in degrees.
What is the range of digital thermometer?
There is a digital thermometer to measure different temperature ranges between -200 and 1800ºC. Measurement of temperature is done in many different industry sectors.
What is the uncertainty of a digital thermometer?
For a thermometer with a mark at every 1.0°C, the uncertainty is ± 0.5°C. This means that if a student reads a value from this thermometer as 24.0°C, they could give the result as 24.0°C ± 0.5°C. For a digital measuring instrument, the uncertainty is half the last digit shown on its display.
Who invented digital thermometer?
Galileo Galilei is the person who invented digital thermometer. He was also a mathematician, engineer, physicist, astronomer.
Who invented thermometer?
1612: Santorio Santorio – the first thermometer
The Italian, Santorio Santorio (1561-1636) is generally credited with having applied a scale to an air thermoscope at least as early as 1612 and thus is thought to be the inventor of the thermometer as a temperature measuring device.
Why are digital thermometer popular in recent times?
Digital thermometer are used these days instead of clinical thermometers because: Digital thermometers are designed to be more accurate. … Digital thermometer provide temperature readings in decimals which more accurate compared to mercury thermometer.
Why is a digital thermometer important?
Digital thermometers provide temperature readings in decimal points, for an accurate and specific reading. They are multifunctional: you can find digital thermometers coupled with timers or alarms for different uses.
