Buying A Medical Thermometer

It is essential to have an accurate medical thermometer when you are sick.   A thermometer that gives a false reading can lead to misdiagnosis. You must know what to look for when buying a medical thermometer. The following is a list of five things to consider when making your purchase:

1. Use And Purpose

The first thing you should know about any medical device is what it is for. Then, it helps to understand how to use it, including the correct techniques for taking temperatures.

The thermometer is a device commonly used in measuring body temperature. There are many different types, which can be grouped into two main categories:

The thermometer must be placed in a specified place and used appropriately in both cases. For ear medical thermometers, you need to hold your earlobe gently and place the thermometer in your ear canal. Rectal thermometers should be placed inside the rectum an inch or two for an accurate reading.

2. Technology Used

Depending on the purpose, several technologies are available in diagnostic thermometers.

A popular choice has been the electronic thermometer. It uses a technique in which a small current passes through a wire filament. The heat generated by this current is measured, and this measurement is transformed into a temperature. For example, the mercury-in-glass thermometer measures the thermal expansion of materials, such as mercury. The electronic thermometer is often used for babies, but it should not take ear canal temperatures. Ear canal temperatures are notoriously inaccurate when taken with this type of thermometer.

Auscultatory or tympanic medical thermometers measure the infrared energy emitted by the eardrum and convert that into the equivalent temperature. It is considered accurate for infants up to 5 years old but may not be as precise for adolescents and adults.

A commercial thermometer is a non-invasive, disposable device that measures the infrared energy transmitted through the skin. It does not use the contact and is appropriate for those who cannot take temperatures by mouth, such as those recovering from throat surgery.

It should be noted that all of the devices mentioned earlier are considered safer for children compared to a mercury thermometer. When opting for a non-mercury device, be sure to follow the manufacturer’s instructions.

A rectal thermometer is considered safe and accurate for pregnant women as long as it is used properly.

3. Microprocessor And Digital Memory

A microprocessor is an integrated circuit that contains a computer on a single chip. For example, the microprocessor in a good thermometer enables advanced memory functions, including recalling the last measurement. This can be beneficial in the event of a fever, when you may need to take your child’s temperature several times in one day.

4. Number Of Readings

This is an essential consideration for those who often plan to use a thermometer. In general, the more readings it stores, the better. If you choose a thermometer with a low number of readings, you may have to replace it soon after buying.

5. Price

The price of a thermometer can vary greatly, depending on the features it offers. For example, you will have to pay more if you want an ear thermometer that also takes the room’s temperature or displays it on an LCD screen. If all you are looking for is an accurate rectal or oral thermometer, you can find one that fits your budget. Remember, there is no need to buy the most expensive thermometer on the market if you do not plan to use it often.

Final Thoughts

If you’re in the market for a new medical thermometer, there are a few things you should consider before making your purchase. We’ve outlined five key points to think about below. By following this advice, you can be sure that you find the perfect thermometer for your needs and get years of accurate readings. So, what are you waiting for? Start shopping now!
