- Mercury thermometers provide accurate temperature readings, and are often preferred in medical settings where precision is crucial.
- They are also easy to read, with clear markings for the temperature scale.
- Mercury is a good conductor of heat, so the thermometer responds quickly to temperature changes.
- Mercury thermometers have been used for many decades, and are therefore a well-established and trusted technology.

 

- The biggest downside of mercury thermometers is that they contain a toxic substance, mercury, that can pose health and environmental risks if the thermometer breaks or is improperly disposed of.
- Due to this, there are now many non-mercury alternatives available, such as digital thermometers, that are safer and more convenient to use.
- Mercury thermometers are also fragile and can break easily if dropped or mishandled.
- Furthermore, they are not suitable for measuring high temperatures, such as those found in ovens or fireplaces, as mercury boils at 356.73 degree . 

 

Additionally, digital thermometers are much more user-friendly than mercury thermometers. They come with large and easy-to-read displays that show the temperature in both Celsius and Fahrenheit. Most digital thermometers also have audio alerts that notify you when the temperature has been reached.

 

1. Measurement range: 32 degree -42 degree
2. Accuracy: ± 0.1 degree (±0.2℉ )
3. Beeper function,Fever alarm
4. Last measuring reading
5. Measurement time: 60 ±10 seconds in oral,100 ±20 seconds under armpit
6. 1.5V button battery

 

Thirdly, digital thermometers are more convenient and hygienic to use. They do not require any cleaning or sterilizing after use, unlike traditional thermometers that require careful cleaning and sterilizing to prevent cross-infection.
