Types of Thermometers: Medical, Bluetooth, Leave-in Meat, Liquid, Grill

Medical Thermometers

These handy devices are essential for monitoring health. Digital thermometers provide quick, accurate reads of your temperature to detect fevers. Ear thermometers are convenient but can be less precise. For the little ones, temporal artery thermometers gently scan the forehead for a temperature read.

Bluetooth Thermometers

How cool is this - a thermometer you can monitor from your phone! Bluetooth thermometers connect to an app on your device so you can keep tabs on the temperature of spaces like your baby's room, wine cellar or greenhouse. Some even provide alerts if the temp goes too high or too low. The smart home just got smarter!

Leave-in Meat Thermometers

For perfectly cooked roasts, steaks and turkey, a leave-in meat thermometer is a must-have. Simply place the probe in the thickest part of the meat and the display outside the oven door tracks the internal temperature. Once it reaches the ideal temp for your cut of meat, dinner is served! Some leave-in thermometers are also Bluetooth enabled so you can monitor from your phone.

Liquid-filled Thermometers

The classic glass thermometers filled with galinstan liquid metal are decorative and nostalgic. The liquid expands as it heats up and contracts as it cools, allowing you to gauge the temperature. While not as accurate as digital for most uses, liquid thermometers add vintage style when used as room decor or in a garden.

Grill Surface Thermometers

For flawless grilling, you need to know the temperature of your cooking surface. Grill thermometers clip onto the grate or hang suspended above the coals or burners. They measure the ambient heat so you know when the grill is hot enough for veggies, meat, or seafood. No more guessing - get the perfect sear every time!

How Thermometers Help Us Everyday

Thermometers are one of the most useful tools we have for measuring temperature. These handy devices are a part of our daily lives in so many ways!

Monitor Health

The most common use of thermometers is to monitor body temperature and health. Oral or ear thermometers can quickly tell if you have a fever, which often indicates an infection. Tracking a baby's temperature is also important to ensure they stay in a healthy range.

Cooking and Baking

Home cooks and bakers rely on thermometers to check if foods have reached a safe internal temperature or if a recipe is at the proper stage. Candy thermometers are essential for making treats like fudge, toffee, and candies. Digital probe thermometers can stay in the oven to alert you when your roast reaches the perfect degree of doneness.

Heating and Cooling

Thermometers placed around the home help control the temperature for comfort. Thermostats use thermometers to regulate heating and air conditioning units. Outdoor thermometers tell you the current outdoor temperature so you know how to dress. Thermometers in freezers, refrigerators, and water heaters also help ensure these appliances are functioning properly and keeping foods/water at a safe temperature.

Whether you're monitoring a fever, baking chocolate chip cookies, or adjusting the thermostat, thermometers play such an important role in keeping you and your home comfortable and your food safe. These useful tools truly help make everyday life easier and healthier. What would we do without them?

Basal Thermometers - Helping You Start Your Family

Basal body temperature thermometers are designed specifically for measuring a woman's temperature when she first wakes up.

Old Reliable - Mercury Thermometers

While not as common today, mercury thermometers were used for generations. They contain mercury, a liquid metal, inside a narrow glass tube. As your temperature rises, the mercury expands and moves up the tube. Mercury thermometers are very accurate but the downside is they contain toxic mercury and require sterilization. They also take several minutes to register a final temperature reading. Still, for those looking for an old-school option, mercury thermometers remain a tried-and-true method.

No matter which type you choose, thermometers are essential for monitoring health and providing diagnosis. In today's world of modern medicine, these useful devices continue to play an important role in keeping us happy and healthy. Check your temperature regularly - your health depends on it!

Thermometer FAQs: Your Medical Thermometer Questions Answered

The thermometer is one of the most useful devices in medicine, allowing us to keep close track of body temperature. Whether you have a traditional mercury thermometer or a high-tech digital model, it’s important to understand the basics. Let’s dive in and get the answers to your thermometer questions!

What are the different types of thermometers?

The most common types are digital thermometers, mercury thermometers, ear thermometers and forehead strip thermometers. Digital and ear thermometers are considered the most accurate. Mercury thermometers are being phased out due to health concerns. Forehead strips are convenient but less precise. Choose a thermometer based on age, personal preference and how accurate of a reading you need.

How do I take an accurate temperature reading?

For oral, rectal or underarm use, place the thermometer under the tongue, in the rectum or under the arm and hold it in place for the recommended time. For ear thermometers, gently place the probe in the ear and press the button to get a reading. For forehead strips, place the strip on the forehead for 10-15 seconds as directed. Make sure not to have exercised, eaten or bathed for 30 minutes before taking a temperature for the most accurate result.

What do the numbers on the thermometer mean?

A normal body temperature is around 98.6°F or 37°C. A fever is usually defined as 100.4°F or higher. See a doctor if temperature exceeds 103°F. Temperatures below 97°F can indicate hypothermia and also require medical attention. Digital thermometers will display the temperature reading in numbers, while mercury and some digital thermometers have markings to read the temperature.

How do I care for my thermometer?

Always follow the instructions for your specific thermometer model. In general, clean your thermometer after each use by wiping it down with alcohol and allowing it to dry completely. Do not immerse most thermometers in water. Store your thermometer in its original packaging in a cool, dry location away from direct heat. Replace mercury or digital thermometers every 3-5 years or sooner if not working properly.
