Thermometers are essential devices that are used in hospitals and homes. These devices are used in hospitals by medical personnel for clinical and emergency use. On the other hand, it is an invaluable tool, especially in homes where kids, toddlers, and babies are involved. This device can help inform guardians of critical body temperature that can have an extremely detrimental effect on a child.

1. Description and Types of Thermometers

There are a handful of different thermometers produced by a wide range of diverse companies. These types provide doctors and users with a flexible temperature measuring tool. The types of thermometers are described below.

1. Glass Thermometer

A glass thermometer is the traditional type of temperature measuring device. It is a glass filament-like device that is filled with mercury as its working fluid. The mercury expands and contracts based on the prevailing surrounding temperature. The outer surface of the glass tube is calibrated to ease temperature readings. The glass thermometer is used in two ways: between the armpit or under the patient’s tongue. After a few minutes in that position, the device is removed, and the temperature is read. The use of this device has been significantly discouraged due to the likelihood of mercury poisoning.

2. Digital Thermometer

The proliferation of electronics has gradually made most medical devices into electronic devices. Likewise, a digital thermometer has been created to measure body temperature. This device is accurate and provides readings quickly. The digital thermometer consists of a digital display, a plastic cover, and a small metallic temperature sensor at the device’s edge. Within the device is an electronic circuit that allows for data processing and presentation. Additionally, the device is powered by a battery. The digital thermometer works by taking readings from the enclosed surfaces of the body. Therefore, temperature measures can be taken from the armpit, under the tongue, and other areas that ensure an accurate reading. This device is widely used in hospitals and is suitable for use at homes.

3. Forehead t]Thermometers

The forehead thermometer works a lot like the standard digital thermometer but less accurate. The difference is that this device doesn’t require physical contact before measurements are taken. Instead, it uses infrared to estimate the body’s temperature. This device has a gun-like structure that allows a third-party to point and measure another person’s temperature.

4. Ear Thermometer

This device also works based on infrared technology. It is placed in the ear of the patient to measure the body’s temperature. Also, it is ideal for kids and babies. However, it is not as accurate as a traditional electronic thermometer.

5. Pacifier Thermometer

The pacifier thermometer, as the name implies, is shaped exactly like a pacifier. This device is used for babies. The device fits into the baby’s mouth, just like a pacifier. After a few minutes, readings are taken off the digital display. The working principle of this device is a lot like a traditional digital thermometer. However, readings can be slightly inaccurate, especially if a baby refuses to stay still.
