What are the types of thermometers?What is their difference?The thermometer is a commonly used instrument to measure body temperature, and the thermometer is available in general families.With the advancement of technology, the types of thermometers are becoming more and more abundant. From the traditional single glass thermometer, it has gradually developed to electronic thermometers and infrared thermometers.The thermometer has gone through a long process of change and has always escorted human health.
Infrared thermometer
What is infrared thermometer?Infrared thermometer is an instrument that measures the body temperature with infrared light waves.The use of infrared thermometers is more convenient.The clear LCD display, the temperature of the forehead -type infrared body thermometer is easy to carry, saving the measurement time, and the entire process of colleagues tested is more hygienic and safer.
Infrared thermometers can be divided into two types: contact type and non -contact type.In contact infrared thermometers, there are common ear thermometers, forehead thermometers, and multi -functional thermometers.It only takes one second to test the accurate body temperature from the ears.When the baby continues to have a fever, you can measure it at any time to quickly learn about changes in body temperature.Gently pull the straight ear canal when using it, insert the temperature measurement head into the ear canal, and press the upper temperature to measure the temperature for one second. You can read the accurate body temperature from the accurate point on the LCD screen.The most common thermometer is the warmer gun.During the temperature measurement, you only need to target the forehead and press the measurement button. The measurement data can be obtained in just a few seconds. It is very suitable for patients with acute diseases, elderly people, infants, etc.However, in the early days of use, because users are not familiar with this operation, they may get several different measurement data. Generally speaking, the maximum value is the data.When users are familiar with, they will be more satisfied with this thermometer.Considering the harm of mercury, more and more families begin to use faster and safe thermometers.
Digital Thermometer
What is the thermometer of the electronic body?Electronic thermometer is an instrument that measures body temperature using the original electronic original.Electronic thermometers have the characteristics of convenient reading, short measurement time, high measurement accuracy, and safe and environmentally friendly. They are not contained in mercury. Therefore, they are becoming more and more widely used in family and hospitals.
Electronic temperature meter is different from the traditional mercury body temperature meter. It uses physical parameters of certain substances, such as resistance, voltage, current, etc., and the determined relationship with the environmental temperature is displayed in the form of numbers.The shortcomings of electronic thermometers are that the accuracy of the value of the value will be affected by factors such as electronic components and battery power supply. The accuracy value is not as good as mercury thermometer.
The measurement principle of electronic thermometer is to use the temperature sensor to output the electrical signal, directly output digital signals or then convert a current signal (analog signal) into a digital signal that can be recognized by internal circuit recognition, and then via the display (such as LCD, digital tube, LED, LED, LEDThe matrix (matrix, etc.) shows that the temperature in the form of digital form can record and read the highest value of the test temperature.
The core component of the electronic thermometer is the NTC temperature sensor that perceives the temperature.The resolution of the sensor can reach ± ??0.01 ° C, the accuracy can reach ± ??0.02 ° C, the reaction speed is <2.8 seconds, and the drift rate of the resistance of the resistance ≤0.1%(equivalent to less than 0.025 ° C).
Mercury thermometer
What is mercury thermometer?Mercury thermometer is the most common instrument to measure thermometer, and is widely used in family and hospitals.Mercury thermometer has the characteristics of accurate measurement results, high stability, and cheap price, so it is widely used.
The thermometer of mercury is the most common thermometer. It can keep the original location with the rising temperature of the body, which is convenient for users to observe at any time.Because the structure of the glass is relatively dense and the performance of mercury is very stable, the vitrus thermometer has the characteristics of accurate display value and high stability, as well as the advantages of low price and no external power supply, which is deeply trusted by people, especially medical workers.However, the shortcomings of the vitrus thermometer are also relatively obvious, crushed, and the possibility of mercury pollution; the measurement time is relatively long, which is inconvenient to use it for patients with severe diseases, elderly people, infants and young children, and the reading is more troublesome.
What is the use of mercury thermometer?
1. Throw the temperature meter below 35 ° C before use.
2. Put your body thermometer under the tongue (hold it, do not bite and speak hard), or underarms.
3. At least 3-5 minutes, the best 7 minutes.
4. Take out the thermometer, read the temperature data, wipe it clean with toilet paper, and disinfect it with alcohol cotton slices (wiped from the tail end to the mercury end).
It should be noted that the thermometer of the mercury is fragile. When you throw it, be careful to prevent crushing.Disinfection after use.
Types of thermometer
How many types of thermometers are?What are the thermometers you know?The thermometer is a common medical instrument. It is small and convenient.There are three types of thermometers, namely mercury thermometers, electronic thermometers, and infrared thermometers.There are many types of thermometers. What are the differences between different thermometers?
1. mercury thermometer
The thermometer of the mercury is a traditional thermometer, which is made of glass, and there is a mercury column that continues to rise with the body temperature.Mercury thermometer has the characteristics of accurate measurement results, high stability, and low price.Mercury stored in the mercury ball at the end.When mercury is heated, it expands and rises along a very narrow glass tube.Therefore, a small change in body temperature will lead to a significant increase in mercury in the glass tube.After the amount of consumed temperature, you must throw the thermometer hard to return the mercury back to the mercury ball.
2. Electronic thermometer
The thermometer of the electronic body uses the physical parameters of certain substances, such as resistance, voltage, current, etc., and the determined relationship with the environmental temperature is displayed in the form of numbers.Electronic thermometers are convenient, short -measurement, and no mercury, which is harmless to the human body and the surrounding environment.The deficiencies are that the accuracy of the value is affected by factors such as electronic components and battery power supply.
3. Infrared thermometer
Infrared thermometers are measured by infrared body temperature. Compared with electronic thermometers, the measurement speed is faster and shorter than the electronic thermometer. It can be divided into two types: contact and non -contact.In contact -type infrared thermometers, there are ear thermometers, forehead thermometers, and multi -functional thermometers. It only takes one second to measure accurate body temperature from the ears.Non -contact infrared thermometer is the most common temperature gun, which can measure the temperature of the human body.Just aim at the forehead and press the measurement button. The measurement data can be obtained in just a few seconds. It is very suitable for patients with acute diseases, elderly people, infants, etc.
