1. Look The correct way to use a thermometer
1. The way to view a mercury thermometer is to face a bright light and look perpendicularly to the front of the mercury column. Avoid touching the metal end with your fingers when checking.
2. A thermometer is a tool for measuring body temperature. It uses the principle of mercury to expand when exposed to heat. The measurement time of the thermometer is different depending on the measurement site. The thermometer takes 5 to 10 minutes to measure armpit temperature, 5 minutes to measure oral temperature, 5 minutes to measure anus temperature, and the time to measure ear temperature and forehead temperature should be according to the product instructions.
3. When measuring the armpit temperature, make sure the armpit is dry. Avoid drinking cold or hot water before measuring the oral temperature. Avoid excessively high ambient temperature when measuring the forehead temperature. or too low.
2. How to look at the thermometer
The line of sight should be in line with the The upper surface of the liquid column should be flat, and then read the corresponding number, otherwise the reading will be too high or too low.
3. How to read degrees on a thermometer
1. Take it out After the thermometer, the end with mercury is on the left side. Hold the opposite side and turn the thermometer under bright light until you find a silver line. The thermometer is usually marked with degrees. Find the temperature corresponding to the last end of the silver line inside the thermometer and read it. .
2. It should be noted that before measuring body temperature, you should pay attention to whether the thermometer is lower than 35 degrees. If not, you should shake it hard until the temperature is lower than the lowest value marked on the thermometer, and the armpit The measurement time should not be shorter than 5 minutes.
4. How to read a 100-degree thermometer
1. Measure correctly After taking the temperature, take out the thermometer and gently rotate the thermometer back and forth. You will see a clear mercury line. The scale where the mercury line is located is the body temperature.
2. Body temperature refers to the average temperature deep in the human body, and the armpit measurement method is often used. A thermometer is an instrument used to measure body temperature. The temperature of the thermometer is used to measure whether there is fever.
5. How to read the degree diagram on a thermometer
Mercury thermometer is made of It is composed of a mercury head and a glass tube. The glass tube is in the shape of a triangular prism. Among the three sides of the triangular prism, one side is white, one side has a scale, and the other side has the numerical value of the scale. When reading a degree, the mercury head faces to the left and the glass tube faces to the right. The scale surface is on the top and the numerical value surface is on the bottom. Look at the edge where the scale surface and the numerical value surface intersect. Gently turn the glass tube. You can see the mercury column against the white surface. The number of scales reached by the top of the mercury column is the degree for measuring body temperature. . Before measuring body temperature, the top of the mercury column in the glass tube should be shaken below 35 degrees.
The most common thermometer is the mercury thermometer. The mercury thermometer is a Mitsubishi structure with fonts on each side. One side is marked with the production date and brand, one side is marked with degrees, and the other side is marked with scale. The scale of a mercury thermometer starts from 35 degrees and ends at 42 degrees. The scale is divided into 14 large divisions. Each large division represents 0.5 degrees and is divided into five small divisions of 0.1 degrees. Hold the tail of the thermometer with one hand, that is, the end away from the mercury column, keep your eye line at the same level as the upper surface of the liquid column in the thermometer, hold it horizontally, then slowly rotate the thermometer, observe while rotating, and see from the front The corresponding temperature value can be read when the mercury column is very thick. Generally, look at the edge between the scale and the numbers. If the scale points upward and the triangle edge faces you, you will see a white mercury line. The corresponding number position is the corresponding body temperature. That is: follow the gap between the scale and the degree to see where the silver line goes.
6. How to read the thermometer value table
1. Thermometer The value meter is divided into mercury bubble and number meter.A mercury bulb is used for temperature measurement and a digital indicator is used for temperature reading.
2. The reading of the indicator is usually 35-42℃. The scale is divided into 14 large divisions, and every two large divisions are 1℃. Use 1°C for labeling.
3. Hold the end of the thermometer with your hand, slowly turn the thermometer until the mercury line can be seen between the degree and the scale, and look directly at the mercury line with both eyes. At the farthest end, the value marked on the left corresponding to the farthest end is the integer part of the thermometer, plus the small grid value part on the right side of the value, the two parts are combined to the final measured body temperature value of the thermometer.
