What Is A Thermometer?

A thermometer is a type of instrument that you can use to measure your body temperature. You may have seen this device in hospitals where nurses and doctors use them to measure the body temperature of patients. In addition, they are also used to measure the temperature of food, water and air. Mercury or diagnostic thermometers are specifically designed to measure human body temperature. Read on to know more.

In this article, we are going to focus on three types of thermometers: mercury, digital and infrared. We will go into the details of each type of units to help you learn more about them. This will make it easier for you to select a unit that can meet your temperature measurement needs. Just make sure you know what you need.

Mercury thermometer

First, you should shake the unit, which will move the mercury inside the tube. Next, you should place the marked portion of the device under your tongue for about two minutes. Do not open your mouth or read during this time may be incorrect.

Another way is to place the meter next to you. For this method, you need to wait a while, which should be at least 3 minutes.

digital thermometer

This device has a heat sensor known as a thermistor. What sets it apart from the mercury type is that it offers more versatility. Also, it can give you accurate readings in less than a minute.

This unit is more complex than the traditional type. These devices have a semiconductor element to measure temperature. The microprocessor inside these thermometers can give readings in less than 30 seconds. This unit gets the required power from a small battery. The internal microprocessor is turned off when kept for an extended period of time.

infrared thermometer

These units use infrared light to measure temperature. You do not need to touch your body with this device to read. A major drawback of meters is that they can only measure the temperature on the surface of something. The advantage is that they can give an accurate reading immediately.
