Types of Thermometer: A Practical Guide by Sara HealthCare

In today's health-conscious world, keeping track of body temperature has never been more important. Whether it’s a seasonal flu, viral infection, or just a general check-up, a thermometer is a must-have in every household. But with so many options available, which one is right for you? This blog by Sara HealthCare, makers of the trusted Sara+Care brand, will help you understand the different types of thermometer, their uses, and why digital thermometers are leading the way.

What Is a Thermometer?

A thermometer is a medical device used to measure body temperature, giving us insight into health conditions like fever or infection. It works through two main parts:

• A temperature sensor, which detects heat

• A display system, which shows the temperature reading in numerical form

Depending on the technology and use case, there are different types of thermometer—some are inserted into the body, some touch the skin, and others don't need any contact at all.

Common Types of Thermometer

Let’s explore the most common and relevant thermometers in today’s healthcare landscape:

1. Digital Thermometer

The most popular and widely recommended thermometer today, especially for home use. It uses an electronic heat sensor to measure body temperature and provides quick, accurate readings. The Sara+Care digital thermometers by Sara HealthCare are designed with user-friendly features and reliable technology, making them safe for all ages.

Why people prefer digital thermometers:

• Fast readings (within seconds)

• Safe (no mercury)

• Suitable for oral, underarm, or rectal use

• Affordable and widely available

At Sara HealthCare, we offer only digital thermometers to ensure our customers enjoy the highest level of safety and convenience.

2. Infrared Thermometer

Also known as a no-contact or forehead thermometer, this type uses infrared technology to detect temperature from the surface of the skin. It's ideal for babies, children, and in public places where quick screening is needed.

Key features:

• Contactless and hygienic

• Instant readings

• Suitable for sleeping babies or multiple users

3. Glass Thermometer (Mercury/Alcohol)

This is the traditional thermometer with a liquid-filled glass tube. Mercury-based thermometers are being phased out due to safety concerns. If broken, mercury can be toxic. Alcohol-based ones are safer but still fragile and slower.

Note: Sara HealthCare does not manufacture or sell mercury thermometers, in line with global health and environmental guidelines.

4. Strip Thermometer

These are plastic strips placed on the forehead. They change color to indicate temperature but are less accurate. They're handy for quick checks but not reliable for medical decisions.

Why Digital Thermometers Are Taking Over

More and more people today are shifting towards digital thermometers because they’re easy to use, quick, and safe. Unlike older models, there’s no need to shake them down or worry about breakage. Modern designs are compact, affordable, and hygienic.

Whether you're caring for a child, monitoring elderly health, or running a clinic, digital thermometers are the smart choice—and that's why Sara HealthCare stands behind its Sara+Care range as the dependable option.
