Thermometer

A thermometer is a device for measuring temperature.

A clinical thermometer consists of a hermetically sealed narrow glass tube with a ball at one end. Inside this tube is mercury, which expands when heated and rises up the tube. The tube is calibrated within the range of possible temperatures in humans (in the range from 35°C to 43.5°C).

To measure temperature with an oral thermometer, it is placed in the mouth. A rectal thermometer is inserted into the rectum.

Thermometer A device for measuring the temperature of a medical thermometer or climate thermometer. It consists of a sealed glass passage and a sealed metal thermometer at the "90-102" level. The tip of the thermometer has an oval metal ball built into it, and an inner rod on which the temperature scale is attached. A medical thermometer consists of a vacuum dome and a hermetically sealed sensitive measuring device (electromechanical or electronic). The measured object is heated by thermal conduction through the mercury capillary. Electromechanical devices are widely used in the field of temperature measurements in the range up to 600 ºC, and

A thermometer is one of the simplest instruments that is used to measure human body temperature. It was invented back in the 19th century and has since been widely used in medicine. Today, a thermometer is used by doctors to diagnose and monitor a patient’s condition.

A medical thermometer consists of a narrow glass tube containing a ball of mercury inside. As the temperature of the mercury rises, it begins to expand and rise up the tube, which is displayed on the thermometer dial. In a medical thermometer, the scale is calibrated over the temperature range from 36.6 to 42 degrees Celsius.

Depending on the method of installation of the thermometer, oral and rectal thermometers are distinguished. A mouth thermometer is the most common type of medical thermometer. It is designed to measure temperature in the mouth. A rectal thermometer should be used if necessary to measure the temperature in the rectum.

Using a medical thermometer has its advantages and disadvantages. It allows you to quickly determine the actual condition of the patient and monitor his condition. In addition, the medical thermometer has high measurement accuracy and can be used in a wide variety of situations. However, there are a number of disadvantages to using a medical thermometer. For example, mercury inside the device is very toxic, and if the thermometer is broken, parts of it can get inside a person, which can lead to poisoning. Mercury is also a dangerous metal; it ranks first in toxicity among all known metals.

In addition, the use of a medical thermometer may cause some inconvenience to patients. Thus, when measuring temperature on the surface of the body, mercury can stick to the skin and leave an unpleasant sensation. This is especially true for older people and people with sensitive skin.

In addition to medical thermometers, electronic thermometers that operate on batteries and are safe and easy to use are often used to measure temperature. However, they are less accurate than mercury thermometers and are not suitable for all types of measurements. For example, infrared thermometers are often used to measure the temperature of liquids and gases.

A thermometer is a device designed to measure the temperature of various bodies, gases, liquids or solids. One of the most common thermometers is medical. It is used to diagnose diseases in children of different ages, as well as adults. Often such a device is used for home self-monitoring of body temperature.

Medical

A thermometer is a device that is used to measure body temperature. It is indispensable in medical practice for diagnosing various diseases, as well as for monitoring the health status of people.

A medical thermometer consists of a narrow glass tube with a ball of mercury at one end. When heated, mercury expands and rises through the tube, allowing body temperature to be measured. The calibration of such tubes is carried out within the range from 36 ⁰C to 42 ⁰C, which corresponds to normal human body temperature.

To measure temperature with an oral thermometer, it is placed in the oral cavity. To measure rectal temperature, the thermometer must be inserted into the rectum. This method of measuring temperature is more accurate, since it does not depend on the presence of hair on the surface of the skin.

In addition to medical ones, there are electronic thermometers. They can also be used to measure temperature, but provide more accurate readings than mercury ones. Electronic thermometers can have various functions, such as memory of the last readings, sound signal, etc.

There is also an infrared thermometer that measures the temperature of objects. It is mainly used for remotely measuring the temperature of various objects. Moreover, the readings of such a thermometer depend on the ambient temperature and can be either distorted or correct.

Measuring body temperature is of great importance in medicine. For example, measuring a patient's body temperature helps identify diseases that are not apparent during a routine examination. These can be infectious diseases or chronic pathologies.

Measuring rectal and oropharyngeal temperatures also helps to recognize the acute phase of the disease and prescribe treatment, and antibiotics are prescribed for infections. At home, temperature measurement can be carried out with an electronic thermometer in the armpit. In this case, it is not recommended to measure the temperature immediately after water procedures - moisturized skin conducts heat better, so the thermometer readings will be distorted.
