How to read a thermometer for fever

Thermometer is used to check the temperature of the body. This is the reason that we use the thermometer to measure the temperature of the person who is suffering from the fever.  The difference here is that whether the person is measuring the temperature with a traditional thermometer or a digital thermometer.

In case you are measuring the temperature through digital thermometer the procedure is very simple. Are you need to do is to make a contact between the body and the thermometer. This contact can be of 3 types.

  • Oral
  • In the armpit
  • Through the rectum

In oral contact the contact of the thermometer is made with the body through the mouth. the thermometer is placed under the tongue. As the contact is being made the temperature can be observed after a short interval.

In the armpit the contact is being made with the skin and with the thermometer. This is the nost easiest way to take the temperature of the body. But this is not the most accurate method. Usually the observation taken during the process of the observation is less than the origin temperature. You can manually ad some degrees in the reading to made it accurate or near to accurate.

Through rectum is not the most easiest way but the most accurate way to measure the temperature of the object. In this method the nob of the thermometer is being entered through the rectum. Good care should be done the insertion should not be more than half inch. Once you feel that there is any hurdle in the way. You must stop. The thermometer should be cleaned properly after the use.
in case you are using a digital thermometer. What’s the temperature is being settled it produces a sound. The display becomes stable and and you can easily read the reading. Incase you are using a glass thermometer you should look for the answer of the next question.

How to read a glass thermometer

These are the traditional old thermometers. In which the mercury is used as a measuring object of the temperature. The procedure is simple. Mercury climbs in a glass tube. This glass tube is marked with the temperature bars. On one side of the glass tube it has been marked with the centigrade and on the other side of the tube the marking is done according to the Fahrenheit system.

To read the temperature on a glass thermometer you need to hold the thermometer horizontally. Do not hold it from the side of the bulb as if you hold it from the side of the bulb. Your body temperature may rise the level of the mercury in the glass tube. In this way you will not be able to get the accurate reading of the temperature.

As an additional tip let us told you that the normal body temperature is 98.6º F or 37º C. you can see a line indicating the normal body temperature. This as a reference line helps you o identify that how low or high is the temperature of the person is.

The next is the glass thermometer that has been placed in the room or outside to grab the atmospheric temperature. These are of two types the indoor thermometers and the outdoor thermometers. These type of the thermometers are usually bounded on a woven board. On both side of the wodden board the temperature mark has been arranged. These temperature marks on one side represents the Celsius and on the either side these marks represents the fahrenheit. Stand in the straight position facing the thermometer. You will c that the mercury level in the tube. Find out right and left you will c the different indications on both slides of the tube. The height of the mercury can indicate the exact temperature of the room or the outside atmosphare. What you need to do is just to locate the temperature mark that is actually very near to the level of the mercury.

How to use mercury thermometer

This phenomena is really simple by using this phenomena this can be used to measure the temperature. This measurement can both be done. First in close contact with the body and the atmospheric temperature can also be done with the help of this thermometer. The mercury is enclosed in a glass tube. On a side of the glass tube a bulb made with the heat transferring material has been installed.

This bulb is actually a type of the container in this container the mercury is being stored. Once the heat is transfer thorough the bulb to the mercury the mercury started to climb. As this started to climb it settles at the place that is stable. Now is the time to take the temperature. On both side of the mercury tube you will c the temperature marks. On one side the marking so done according to the celsius scale and on the other side this marking is done as per the fahrenheit scale so that you may take the reading in the scale that os convenient for you.

Look for the most adjacent mark on the tube at both sides. The most adjacent mark is the temperature you want to observe. Another important thing to remember is that do not touch or hold the bulb from the bulb side. Other wise the temperature will be increased. This temperature increase due to your body heat will restrict the ability to observe the temperature accurately.
