1. What is an analog THERMOMETER?

An analog thermometer for health professionals is a tool for measuring body temperature that uses a mercury or alcohol system and an analog display. It is often used by health professionals to take patient temperatures due to its speed, reliability, and accuracy. The analog thermometer for health professionals is designed to be easy to use and read, with a clearly visible graduated scale. It can be used to take the temperature of different body parts, such as the mouth, ear, armpit, or rectum. It is often used alongside other medical equipment to monitor patients' health conditions.

2. What are the characteristics of an analog THERMOMETER?

Accurate, reliable, and easy to use, this tool for measuring body temperature uses a movable needle to indicate the temperature on a graduated scale. It is often made of glass or sterile plastic for hygienic use in medical environments.


The operation of a professional analog thermometer is based on the principle of thermal expansion. When body temperature increases, the liquid inside the thermometer expands and raises the needle on the graduated scale. The needle's position indicates the measured temperature. To take a temperature measurement, the device is inserted into a body part, such as the mouth, ear, or rectum. The measurement is generally taken after a period of immobilization to allow the thermometer to adapt to the body temperature. Once the measurement is taken, the needle is read on the graduated scale to obtain the temperature.

Accuracy and reliability

The accuracy and reliability of an analog thermometer depend on several factors, such as the quality of manufacturing, the quality of the thermometric liquid, the graduation of the scale, and the calibration. Analog thermometers for health professionals are often calibrated at the factory to ensure maximum accuracy. However, accuracy can deteriorate over time due to glass deformation or liquid evaporation, which may necessitate recalibration. To ensure reliability, it is important to follow the manufacturer's usage and storage instructions and to replace the thermometer regularly to avoid measurement errors.

Advantages and disadvantages

The advantages of an analog thermometer can be summarized in four important points:

  1. Ease of use: no special skills are required to operate it.
  2. Affordable cost: generally cheaper than digital thermometers.
  3. Accuracy: often accurate when used and maintained correctly.
  4. Wide availability: widely available in the medical market.

And as for the disadvantages, because there are some, they can also be summarized in 4 essential points, like this:

  1. Longer measurement time: can take longer compared to digital models.
  2. Reduced functionalities: the analog thermometer generally does not have advanced features like memory or reading storage.
  3. Calibration needed: may regularly require recalibration to ensure its accuracy.
  4. Difficult cleaning: can be less hygienic than digital models.

3. How to choose the right analog thermometer?

When you are a health professional looking for an analog thermometer, it is important to consider the following criteria to make the right choice:

  1. Accuracy: accuracy is a criterion that should be essential in the choice of an analog thermometer. It is advised to ensure that the chosen model is accurate and complies with usual standards.
  2. Reliability: the device's reliability is also very important, as temperature measurements must be reliable to make the right care decisions. Therefore, search for a model with a good reputation for reliability.
  3. Measurement method: Analog thermometers can measure the temperature of different body areas. Therefore, ensure that the chosen model corresponds to the measurement method you plan to use.
  4. Comfort & safety: temperature measurement must be comfortable for the patient. It is important to choose a model that does not cause discomfort or pain to the patient and complies with current safety standards.
  5. Maintenance & cleaning: for maximum durability and reliability, it is recommended to choose a model that is easy to clean and maintain.
  6. Price: Cost may also be an important factor for health professionals. Look for a quality thermometer that fits your budget.
  7. Reputation: check reviews and comments from other professionals to get an idea of the product's reputation.
