One of the most common types of thermometers is the basal body thermometer. It gives you a level of versatility for your family, practice, or educational needs that other styles of thermometer are just unable to provide. They are available with a digital readout, can record temperatures in the mouth, armpit, or the rectum, and results are available in 60 seconds or less on most models. This makes them suitable for infants, children, and adults.

What Are Some of the Benefits of Basal Body Thermometers?
For most homes and practices, the basal body thermometer is an easy way to track the course of an illness. By knowing what your average body temperature is supposed to be (not everyone runs 98.6F as the average), you can know when a minor or major fever is taking place. You can know when home care is advised, when a visit to the doctor may be necessary, and understand more about how someone is feeling.
Couples who are attempting to become pregnant can also benefit from the use of a basal body thermometer. When women chart their basal body temperature right away in the morning, it will become easier to track the hormonal changes which occur in her body throughout her cycle. Over a month or two of data collection, it will then become possible to gather enough empirical data to attempt other forms of fertility treatment if necessary.
There’s also the advantage of cost. For less than the price of lunch, you can grab a solid thermometer that you can keep around at home so you can track temperatures and personal health with much more ease.
Common Issues with Basal Body Thermometers and How To Solve Them
The main issue with a basal body thermometer is a matter of comfort. Many parents especially worry about how comfortable a child is while obtaining a temperature. Under the tongue or rectal temperatures may not always be the first choice of activity for someone, but the results from the thermometers are a benefit that is worth a minor level of discomfort for less than a minute. Be careful not to press too hard if administering to avoid further discomfort.
Basal body temperatures can also be inaccurate if taken orally within 15-20 minutes of eating or drinking something. The temperature of the food or the beverage can affect the reading if taken earlier and give you a false result.
There’s also the issue of being able to keep a mouth closed for those who routinely breathe through their mouths. Having a stuffed up nose can make it difficult to obtain an accurate oral reading as well. In this instance, try using a product like Vap-O-Rub to free up some of the breathing passages, but be careful as to not apply the product to the thermometer.
How to Find the Best Basal Body Thermometer for Me
Choosing a basal body thermometer doesn’t have to be a complicated process thanks to the number of quality of real trial reports and reviews that are available online today. In basic terms, you’ll want to search for three key features when looking for a solid thermometer right now.
- It should have a digital display that is easy to read for every member of the family.
- It should have an accuracy that falls within 1/10 of a degree.
- It should have some level of memory recall.
Some thermometers will also have a final temperature alert that lets you know to check the reading. It can be tempting to try to position the thermometer in such a way that you can read it as it is working, but this can make the final reading be inaccurate. The alarm helps you avoid this temptation.
Other features include a replaceable battery, being easy to handle, and being easily replaceable. Just take a note that some battery-operated models do tend to increase in inaccuracy as their battery life decreases. This means a slow fade may occur which may not always be noticeable.
What Are the Prices of Basal Body Thermometers?
Many portable or travel basal body thermometers can be found today for around $10-$20. These often are designed with flexible materials to eliminate some of the discomfort that comes with using this type of thermometer. Rigid models are still available, but are now more of the exception than the rule, and have about the same price point. Thermometers with more features may cost between $30-$40, but that is typically where the prices top out for this medical equipment.

Eudemon
The advantage which this basal body thermometer brings to the table is an extra -large LED backlit display so you can easily read results. This is useful for those times when you need to take your own temperature. It offers readings in Fahrenheit and Celsius and stores up to 60 readings at a time. Each record shows the date and time of the reading so you can relay a temperature history to a doctor if need be. For those tracking ovulation, an included chart can help you interpret results. For all these reasons, it earns our highest recommendation.

Hyology
The sensation of the metal probe was something we appreciated when testing this thermometer. It also has a flexible design, but because this thermometer is smaller than other models, that flexibility is limited. You’ll receive accurate and fast readings to a medical-grade precision. The alarm function is nice to have and temperature conversions are easy enough to do, but you have to keep pushing the on/off button and that takes some time to cycle through the options. If you’re on a budget, however, it’s tough to find a better basal body thermometer than this one.

Marnur
Very few thermometers these days are approved for underarm use, but this is one of the few models that are. Its FDA approved and works with pets just as well as it does for kids and adults – but maybe keep the one for the pets separate. The battery life is rated at 200 hours for this unit, though no battery actually comes with the unit. You’ll need a 1.5V DC button battery – size LR41 or SR41 works. Low or high temperatures have a greater chance for error, but these would also be considered medical emergencies where this thermometer shouldn’t be used. All in all, it’s a good price on a solid basal body thermometer.

We like this basal body thermometer because it offers smartphone compatibilities in addition to storage for up to 40 temperatures. The app allows your mobile device to chart, store, text, or even email your daily readings if you prefer. It supports multiple operating systems and works fine as a stand-alone thermometer as well. It folds down into a compact storage mode for easy portability and audio is available in multiple languages. If you want a thermometer that can really do almost everything, this is the one to get.
