The device which is used to calculate temperature is called Thermometer. #What is clinical thermometer? The device which is used to calculate the temperature of our body is called Clinical Thermometer. Structure of thermometer - A long narrow tube with a same thickness throughout the length. On one side of this tube there is a bulb which contains mercury. Also, for reading the temperature there is a scale on the thermometer. The normal temperature of our body is 37 °C. However it can vary between 35° C to 42 °C therefore the clinical thermometer has reading from 35 °C to 42 °C. Why is a laboratory thermometer not used to check body temperature? You have got fever. Why don't you check your body temperature using a thermometer? No. Please don't use a laboratory thermometer. You won't be able to get the correct reading. Why don't you try another one? This is called a Clinical thermometer. A clinical thermometer is different from a laboratory thermometer. Seems like you have made your choice. A clinical thermometer has a kink. When we check our body temperature, the kink present in it prevents the mercury from falling back down, thus helping the thermometer to hold the temperature recorded by it and giving us an accurate reading. Now, in a laboratory thermometer, this kink is absent. This is because a laboratory thermometer is meant to measures immediate temperature. Hence, after recording our body temperature, until we check it, the mercury will fall, thus not giving us an accurate reading. Types of Thermometer - Uses of Thermometer - Thermometer Types #Types of Thermometer Thermometers are widely used in technology and industry to monitor processes, in meteorology, in medicine, and in scientific research. There are many different types of thermometer available in today’s market. Before you make your purchase, it is vital that you are made aware of the range of products available to you. You should also understand and consider each type of thermometers suitability for various different uses. Learn how to check temperature or fever at home by using a mercury thermometer. Shake the thermometer to get mercury level well below the red line. Then put it in your armpit or in the mouth below the tongue for about 3 minutes. Then check the reading as shown. Mercury level should be below the red line. Once it is above the red line, it means you are having fever. Red line is at 98.6 degree Fahrenheit or 37 degree Celcius. Below red line is normal temperature. Above red line is fever. Human temperature is usually measured in Fahrenheit units. #Thermometer
