What are the advantages and disadvantages of digital 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 is the advantage and disadvantage of clinical thermometer?

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 advantages of using a digital thermometer?

Benefits of Digital Thermometers

Digital thermometers can read temperatures fast and with high accuracy. They are handy and easy to use; you can even carry the thermometer in your bag. The display is easy to read. A digital thermometer isn’t expensive.

What are the disadvantages of mercury thermometer?

Disadvantages
  • It is highly toxic for living beings and the environment if the bulb breaks and mercury leaks out.
  • Mercury is difficult to clean, and it can contaminate the surface on which it leaked.
  • It cannot measure cold temperatures.
  • It has low thermal co-efficient.

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 are the advantages and disadvantages of mercury?

Difference between Advantages And Disadvantages Of Mercury And Alcohol Thermometer
Advantages Disadvantages
Mercury thermometer
cheap display is harder to read
durable does not work below -390C (Hg freezing pount)
accurate cannot be used for thermograph

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 advantages and disadvantages of mercury as a thermometric liquid?

Advantages of mercury as a thermometric liquid. –It is a good conductor of heat and therefore the whole liquid reaches the temperature of the surroundings quickly. -It does not wet (cling to the sides of) the tube. -It expands uniformly (linear expansion) and responds quickly to temperature changes, hence is sensitive.

What are the three advantages of using mercury in thermometer?

It does not stick to the glass tube. It expands on providing heat to it. It has lower freezing point and higher boiling point. It is a shining metal and when it expands, the expansion can be easily seen.

What are the advantages of using mercury in a thermometer instead of water?

Mercury is the only one in liquid state at room temperature. It’s used in thermometers because it has high coefficient of expansion. Hence, the slightest change in temperature is notable when it’s used in a thermometer. It also has a high boiling point which makes it very suitable to measure higher temperatures.
