What are the advantages and disadvantages of each type of thermometer?
The advantages of digital thermometers are that they are inexpensive, easy to read, require very little maintenance and give an accurate reading. The disadvantage is that they get damaged easily if dropped and the battery powering them eventually runs out.
What are the advantages and disadvantages of using digital thermometer over mercury thermometer for temperature measurement?
Digital thermometers provide faster results Digital thermometers provide fast results as opposed to mercury thermometers whose readings are slower to realize because you have to wait for the mercury to heat and then slowly rise to display the temperature.
What are the different types of thermometer and their uses?
Types of thermometer
- Digital thermometers. Digital thermometers are quick to use, reasonably accurate and can be used under the armpit (always use the thermometer under the armpit with children under 5).
- Ear (or tympanic) thermometers.
- Infared thermometers.
- Strip-type thermometers.
- Mercury thermometers.
What are the advantages and disadvantages of liquid in glass thermometer?
| THE LIQUID-IN GLASS THERMOMETER | |
|---|---|
| Advantage | Disadvantage |
| no power source required | limited to applications where manual reading is acceptable, e.g. a household thermometer |
| repeatable, calibration does not drift | have a limited useable temperature range |
| easy to use & cheap | cannot be digitised or automated |
What are the disadvantages of an infrared thermometer?
The Limitations of Infrared Thermometers
- Only measure surface temperatures and NOT the internal temperature of food or other materials.
- Require adjustments depending on the surface being measured (See Adjust for Emissivity)
- Are not thought to be as highly accurate as surface probes measurements of the same *surface.
What are the disadvantages of the electronic thermometer?
What are advantages and disadvantages of mercury thermometer?
A thermometer comparison
| advantages | disadvantages |
|---|---|
| Mercury thermometer | |
| cheap | display is harder to read |
| durable | does not work below -39 C (Hg freezing pount) |
| accurate | cannot be used for thermograph |
What are the disadvantages of using mercury in thermometer?
The Weaknesses or the disadvantages of Mercury:
- It cannot measure very low temperature, because its freezing point is high (-40ºC)
- Mercury is poisonous, so it harmful if its tube is broken.
- Its price is very high.
- display is harder to read.
- cannot be used for thermograph.
- slow response.
- fragile.
What is the type of thermometer?
Types of Thermometer Clinical thermometer /medical thermometer. Digital thermometer. Infrared ear thermometer. Mercury thermometer.
What are some disadvantages of using a glass thermometer?
Disadvantages. Liquid in glass thermometers tend to be fragile and hence easily broken, can only be used where the liquid column is visible, cannot be used for surface temperature measurements, cannot be read from a distance and are unsuitable for high temperature measurements.
What are the advantages of liquid in glass thermometer?
Advantages
- They are comparatively cheaper than other temperature measurement devices.
- They are handy and convenient to use.
- Unlike electrical thermometers, they do not necessitate power supply or batteries for charging.
- They can be frequently applied in areas where there is problem of electricity.
What are the advantages and disadvantages of thermometers?
The advantages of these types of thermometers is that they are cheap, easy to read, can be submerged in liquids, require very little maintenance and are reliable. The disadvantages are that they break easily and there is risk of mercury poisoning if the glass tube breaks.
What are the two main uses for thermometers?
There are two main uses for thermometers: industrial and medical. Let’s go into the types of thermometers, advantages and disadvantages of each, and other factors you should consider before you buy. Thermometers have many uses in industrial settings.
What should normal temperature be on a thermometer?
If your thermometer has adjustable emissivity, you can set it to 0.78. If you are using fixed emissivity, you can add 5 degrees to your forehead temperature. You could also just accept a reading of 91F-95F as normal temperature, and anything higher than that as a fever.
Which is more accurate strip thermometer or body temp?
Strip thermometers are inexpensive and quick to use. However, since they measure skin temperature rather than body temperature, they’re significantly less accurate and should be avoided.
