How to look at the scale of the mercury thermometer

Mercury thermometerLook at the power method: Holding the tail end of the thermometer, the scale plane is on the top and the digital plane is on the bottom, gently turn the thermometer, you can see the mercury column on the column where the digital plane and the scale plane intersect, and the position of the body temperature reached by the mercury column head is the degree of the thermometer.

Mercury thermometers are an important tool for measuring body temperature and are in the shape of triangular prisms.

shape, with mercury head on one side, there are three sides in the triangular prism, the digital face scale surface and the white side, the degree of the thermometer starts from 35 and 42, and the scale is divided into 14 large grids, each large grid represents, and is divided into five small grids. Hold its tail with your hand and gently turn it repeatedly to see a line of mercury. Put the silver head under the armpit for about 15 minutes, then take it out, look at the position of the mercury line along the gap between the scale and the degree, and calculate the temperature number.

Keep a mercury thermometer while taking temperature.

Sufficient time in the armpit for the measurement to be relatively accurate.

Precautions for mercury thermometers.

Mercury thermometers are usually used to measure the temperature of the armpits, and the mercury column in the thermometer should be thrown firmly below the scale of 35 degrees before measurement, and then the mercury end of the mercury thermometer should be placed in the armpits.

The center, pay attention to the position as much as possible to avoid deviation.

Pay attention to clamp the thermometer with appropriate force, and add 5-10 minutes, if the time is not enough, or the force is loose in the process of measurement, resulting in the thermometer falling off, in this case it may affect the measurement results, you should repeat the above operation, and then re-measure, start the measurement again.

(1) There are two parts commonly used to measure body temperature, namely the oral cavity and armpits.

2) The thermometer is a Mitsubishi structure with a font on each side, one side is marked with the date of manufacture and brand, one side is marked with degrees, and the other side is marked with a scale.

3) The degree of the thermometer is from 35 degrees to 42 degrees, and the scale is divided into 14 large grids, and each large grid represents the degree and is divided into five small degrees.

4) After bringing the thermometer, hold the tail of the thermometer with your hand and turn the thermometer to the middle of the degree and scale.

5) Gently turn it repeatedly, and you will see a silver line (mercury). Look a little more and you'll see.

6) Hold the tail of the thermometer, gently shake the thermometer to the scale below 35 degrees, and then put it under the armpit (silver place) for 10-15 minutes and take it out.

7) Follow the gap between the scale and the degree to see the silver line to **, the current temperature is in degrees.

The degree of the thermometer is from 35 degrees to 42 degrees, and there are 14 large grids on the scale, one large grid represents the degree, and one large grid is divided into five small grids, each small grid represents the degree.

Before measuring the body temperature, it is necessary to forcefully throw the mercury back into the ball of the thermometer to avoid errors after the measurement. The oral or anal temperature is measured for 3-5 minutes, and the axillary temperature takes about 10 minutes before the reading is taken.

Mercury thermometer is mainly composed of mercury head and glass tube, mostly in the form of a prism, when the patient sees the mercury line, there should be a ridge facing the line of sight, which can be used as a standard to find the mercury line. When reading, you should pinch the tail of the thermometer, place the thermometer parallel to the line of sight, or slightly higher than the level of the eye line, and rotate slowly in a bright place, you can see a red or silver mercury column, when observing the thermometer power, you should pay attention to the mercury head to the left, the glass tube to the right, the scale to face up, and the value to face down, and the value is the accurate body temperature.

The mercury thermometer looks at the scale to see the position of the mercury column finger.

The scale of the mercury thermometer ranges from 35 to 42 degrees, and each degree is divided into ten cells, each of which represents a degree. When the mercury thermometer has finished measuring the body temperature, pinch the non-mercury end of the thermometer and rotate the thermometer when you see the scale and the mercury column. If the mercury column is between 36 and 37 degrees, then count the cells between 36 and 37 degrees, and if it is four cells, the body temperature is measured in degrees.

Mercury thermometers often break the mercury column, and the methods of elimination are:

1. Cold repair method: insert the thermometer temperature package into the dry ice and alcohol mixture (the temperature shall not exceed -38) for cold shrinkage, so that all the mercury in the capillary tube shrinks to the temperature measuring bag.

2. Thermal repair method: slowly insert the thermometer into the thermostatic bath with a temperature slightly higher than the upper limit of the measurement, connect the broken part of the mercury with the entire mercury column, and then slowly take out the thermometer and gradually cool it to room temperature in the air.

Kiss! Hello, happy to answer your <>

Pro, the method of reading the scale of the mercury thermometer: when reading the scale of the mercury thermometer, you need to hold the tail of the thermometer with one hand, that is, the thick end of the old god Jing without mercury mercury. At the same time, rotate the thermometer to a position where the scale is at the same level as the eye line, and observe the indicator scale of the mercury column.

where 1 small cell is a degree, and 1 large cell is 1 degree. The thermometer of mercury is very thin, it is a polyhedron to rotate to the direction of several sides and their own line of sight, so that you can see the silver-white mercury column, the corresponding cough scale value of this column, is the value measured at that time, from one direction, if you do not see the mercury column, you can slowly rotate the direction to call the river to see, from the bottom to the upward side, because the mercury column is through thermal expansion and contraction and display the value, so there is mercury below. Look closely at a silver line displayed on the scale.

And the eyes you have to rotate, rotate to the side of the reading and yourself. Hope mine can help you <>

If you have any other questions, you can ask me again<>

Dear, I have sorted out the following methods for you to see the scale of the Mizuno orange silver thermometer:1When reading, the white side rushes forward, and the corresponding scale on the mercury line is compared with the corresponding value below through the edge of the convex lens.

2.There are 3 edges at the end of the reading, the background surface is white, and the upper end is a scale, the scale is between 35 -42, every 1 small scale is, and the bottom corresponds to the scale reading, for example. Kiss, pay attention when reading, the thermometer should be oriented towards a relatively bright place, not towards a particularly dark place, otherwise it will not be very clear.

The line of sight should be straight to the thermometer, not to the left or to the right. <>

The above information about the loss of the group**Zhihu.

How to see the mercury thermometer degree:

1. The thermometer is a Mitsubishi structure, with contents on three sides, one side is marked with the production date and brand of the thermometer, one side is marked with the temperature degree, and the other side is marked with a scale.

2. The degree of the thermometer is from 35 degrees to 42 degrees, and the scale is divided into 14 large grids, each large grid represents the degree, and each small grid represents the degree.

3. After holding the thermometer in your hand, pinch the tail of the thermometer with your hand and turn the thermometer to the middle of the degree and scale.

4. Turn the thermometer to the middle of the degree and the scale, you will see a silver line, if you don't see it, turn it up and down and look for a while to see it.

5. When you want to test the body temperature of a person, hold the tail of the thermometer, gently shake the thermometer, let the silver line of the thermometer scale drop below 35 degrees, and then clamp the thermometer (silver place) to the armpit, and take it out after 10 15 minutes.

6. When the time is up, take out the thermometer from under the armpit, and follow the gap between the two sides of the scale and the degree to see the position of the silver line rising. Read the number next to the silver line is the degree, and you can see that the current thermometer is the degree.

Mercury thermometers often break the mercury column, and the methods of elimination are:

1. Cold repair method: insert the thermometer temperature package into the dry ice and alcohol mixture (the state noise temperature shall not exceed -38) for cold contraction, so that all the mercury in the capillary tube shrinks to the temperature measurement package.

2. Thermal repair method: slowly insert the thermometer into the constant answer closed sail temperature trough with a temperature slightly higher than the upper limit of measurement, so that the mercury fracture part is connected with the entire mercury column, and then slowly take out the thermometer and gradually cool it to room temperature in the air.

Summary. Pro, mercury thermometer is a commonly used medical device to measure body temperature. The mercury thermometer consists of two parts, the silver part is the mercury column and the other side is the reading end.

There are 3 edges at the end of the reading, the background is white, the upper end is a scale, the scale is between 35 -42, every 1 small scale is, and the following corresponds to the scale reading, such as this scale comparison. Therefore, when reading, the white side rushes forward, and the corresponding scale on the mercury line is seen through the edge of the convex lens, and the corresponding value below is compared.

There are 3 edges at the end of the reading, the background is white, the upper end is a scale, the scale is between 35 -42, every 1 small scale is, and the following corresponds to the orange reading, such as this scale comparison.

Therefore, when reading, the white side rushes forward, and the corresponding scale on the mercury line is seen through the edge of the convex lens, and the corresponding value below is compared to the reading of the rubber line.

When reading, it should be noted that the thermometer should be oriented towards a relatively bright place, not towards a particularly dark place, otherwise it will not be very clear, such as facing a light bulb or a reference lamp. The line of sight should be perpendicular to the thermometer, and should not deviate to the left side of the disadvantaged type, nor to the right side. Deviation from the left side or deviation from the right side may cause the reading to be different, and only the correct reading is accurate.

If you do the above, you will be able to read the exact value. Rent fingers.
