Best Basal Thermometer 2017 – Reviews & Buyer’s Guide

A basal thermometer will come in handy when you are trying to conceive in vain. The signs of ovulation are not always so apparent, at least not for everyone. You will agree with me that choosing the best basal thermometer in the sea of thermometers is a tedious task.

One that you do not want to get into if you know nothing about basal thermometers. Read on to know more.

What are Basal Body Temperature Thermometers?

Basal temperature refers to the base temperature after a period of rest. This temperature is the same every day when a woman is not ovulating. However, there is a significant rise, between .4 and .6 when the woman is ovulating.

So, where do you take this basal temperature from? You can take oral or vaginal basal temperature. Either way, you will get good results. However, when testing for ovulation, vaginal temperature is the most accurate.

Basal thermometers are either glass or digital. While the digital thermometer is more accurate, it is relatively costly.

Best Basal Thermometer – Buyer's Guide

When shopping for a basal thermometer. You will need to consider the following factors:

Do you need a digital or a glass thermometer?

Glass thermometers are being faced off by digital thermometers thanks to the accuracy that the latter offer.

The digital thermometers are easy to read and take relatively less time to take your basal temperature. They are also less fragile, making them last long.

The glass thermometers, on the other hand, are fragile. However, they are less expensive, making them ideal for budget buyers.


Most digital thermometers show readings up to 1/100 of a degree. This makes them very accurate. However, there are units that offer a tenth of a degree; this means they only show one decimal point.

The latter are less accurate and may not record minimal changes in body temperature. I recommend you buy one that shows readings up to a hundredth of a degree.

Ease of Use

Using a basal thermometer is a straight forward process. You just put it into your mouth, vagina, rectum or armpits and you will have your readings within one minute.

Best Basal Thermometer

The design of the thermometer will determine how hard or easy it is to use. While most units have a narrow width, some have a relatively uniform width that may confuse users. Digital thermometers with many features are great, but are comparatively challenging to use.


If you are pressed for time, obviously, you will need a unit that works fast. Some digital thermometers can take readings in less than 10 seconds while most take up to a minute. Those that take relatively longer time are more accurate.

Other Considerations

Comfort: If a thermometer does not feel comfortable when in use, reconsider buying it. The narrow end of the thermometer determines how comfortable it feels.

Accessories: There are units offered with long lasting batteries, ovulation charts and user manuals. These accessories will help you get started.

Ergonomics: While a compact unit is preferred due to the comfort of use, a very narrow thermometer might present a handling challenge. Choose the right size to use the unit with ease.

Basal thermometer customer reviews: You have to consider what other users say about the unit before you buy.


While choosing the best basal thermometer might be as easy as picking a popular brand, I suggest you take your time and choose the best.

The above reviews show the best units, but then again, you will still need to choose the one that meets your needs without breaking your bank.

All thermometers offer you a way to track your cycle and know your fertile days. But the above are among the leading in the industry.

If you direly need that pregnancy, pick one of them. If you have any further questions about the basal thermometer, please don’t hesitate to contact us.
