A thermometer is a medical device, used for health care, to measure body temperature. There are two parts that make up a thermometer: the display screen and the temperature sensor.
What types of thermometers are there? What is the effect?
Naming the types, we have 3 basic types such as electronic thermometers, mercury thermometers, digital thermometers.
Along with our points through the pros and cons of each type slightly.
-
Digital Thermometer:
This is the newest device manufactured based on the latest technology now.
Advantages:
- Fast measurement time and highly accurate results.
- There are many modern utilities and functions.
Defect:
- The price is relatively high so it is not yet popular.
-
Mercury thermometer:
This is the type commonly used in hospitals or clinics, with high accuracy. This device is composed of two parts, a temperature sensor, and a gauge.
The device works on the principle of the thermal expansion of mercury. The gauge will show a certain number, exactly equivalent to the expansion of mercury when bringing the thermometer into contact with body temperature.
Advantages:
- Works at any time, regardless of power.
- Has a pretty cheap price.
- Measurement results are almost accurate, the difference is very small.
Defect:
- Only has the function of measuring body temperature.
- It takes a long time to get the measurement results.
- Because it is made of glass, it can break, so it accidentally falls or collides, the mercury contained inside is extremely dangerous if it falls on people.
- Usage is quite complicated.
Mercury thermometers must be used with extreme care and expertise, so they should only be used within hospitals or clinics.
-
Electronic thermometer:
This is a product born to improve and perfect the disadvantages of mercury type. This device works thanks to the infrared heat sensor feature. Capable of measuring body temperature in a short time with high accuracy.
Advantages:
- Utility design. Not only the forehead, but the mother also measures many parts of the baby’s body.
- Suitable for use by all ages, safe to use without worrying about breaking thanks to its sturdy, good-strength design.
- It is possible to measure the temperature accurately in a short time of about 5 – 10 paper.
Defect:
- Compared to mercury thermometers, the accuracy is not equal. The degree of deviation of the electronic type compared to the mercury type ranges from 0.2 – 0.5 degrees Celsius.
- The price is higher than the mercury thermometer.
Types of electronic thermometers:
To suit each location on the body, electronic thermometers have many different types such as:
Forehead temperature measurement:
This is the type that is used a lot because it is quite convenient, simple to use, does not need to touch the human body. This type is composed of two infrared sensor parts: one part is used to measure the ambient temperature, the other part is used to measure the peak temperature.
You just need to bring the thermometer close to the patient’s forehead, after a few seconds the LED screen or LCD screen clearly displays the measurement result. This is a highly accurate result. Therefore, a forehead thermometer is the most preferred device compared to other types
Axillary, oral, or groin thermometer:
This is a device that measures in the armpit, mouth, or groin, however, users often measure in the groin or armpit locations. One disadvantage of this measurement method is its low accuracy and long measurement time.
Ear thermometer:
Using this type of thermometer is very simple, just put it on the eardrum for about 1-2 seconds and you will get the results. However, this method is also quite limited, because measuring in the ear often brings discomfort to the baby.
On the market, there are also electronic thermometers used in some positions such as vagina, anus, … Measuring in the rectum is the part that has almost absolute measurement results, however, it is rarely used. applied because this way is very unhygienic.
In short, the most used electronic thermometer to date.

The third criterion to consider is the amount of memory. It allows you to save the measurement results. For an electronic thermometer product, the memory usually stores 25 – 50 results depending on the type. This helps users to be proactive and easier to monitor their health a lot.
4. Measurement errors
The measurement error of the electronic thermometer usually ranges from 0.2 – 0.3 degrees Celsius. High accuracy is guaranteed. This is also the reason why this device is quite popular.
5. Long-lasting battery
Usually, the longer the battery life, the more convenient it is. Currently, electronic lines often use 1.5V AAA batteries with an average life of up to 6 months. After the battery is exhausted, you just need to replace the battery to continue to use it.
6. Display for monitoring
Electronic thermometers are often equipped with an LED or LCD display of data information with moderate light. Help us to track and observe easily and accurately.
7. Warranty period
Normally, electronic lines are usually warranted for 2 years, you can rest assured when choosing.
8. Additional functions
Some products are equipped with additional utilities such as the appearance of a red screen along with a continuous alarm to warn that the body temperature has exceeded the normal level, greater than 37.5 degrees Celsius. From there, you can handle it. timely in the worst conditions.
