#4. Clinical Basal Thermometer - BBT-113A2A by iProvèn

best basal thermometer

Editor Rating

The Clinical Basal Thermometer by iProven is made to be the “perfect companion for family planning.” The manufacturer does not recommend this tool for everyday medical applications. It is specifically designed to track ovulation and help with planning pregnancy.

This highly-sensitive device is described as an “actual temperature thermometer.” It measures BBT accurately within 1/100th of a degree.

It can take up to a minute to get a reading with this thermometer, but that’s intentional. Rather than opting for a quick temperature measurement, the technology takes it’s time to record an accurate reading. This eliminates potential errors and gives you the right information you need while planning for a family.

Why does slow make sense? If you're taking your temperature orally, the air you breathe in-and-out of your mouth actually cools down your mouth tissue. This can lead to a reading that is inaccurate by up 0.2-0.5 degrees.

While this slight difference isn’t a big deal if you’re just checking for a fever, these increments matter a lot when your tracking ovulation. So, iProven designed a thermometer that took this discrepancy into account - and all it takes is a little more time.

Pros

  • Intelligent digital algorithm eliminates room for error when taking an oral temperature.
  • Produces supremely accurate temperature readings.
  • Provides a reliable reading each time.
  • Smooth, small design for gentle oral use.
  • Flexible, “soft” tip for additional comfort.
  • Simple user interface - just press one button to take a reading.
  • Memory function recalls the last temperature taken.
  • Compact size for easy, convenient travel.
  • Comes with a hard storage case included.
  • Backed by a “Promise of Quality, Education and Simplicity.” If you’re unhappy with your
    purchase, the manufacturer (iProven) will provide a “a hassle-free refund within 100 days from
    your purchase.”

Cons

  • Takes longer than other thermometers, up to a minute.
  • Not designed or recommended for everyday medical applications.
  • No back-light can make the LCD screen hard to read.

#5. MABIS Basal Thermometer

Best Basal Thermometer

Editor Rating

This digital basal body temperature thermometer is a convenient tool for natural family planning. This device helps you by recording your daily BBT. It comes with a 12 month supply of ovulation charts to assist you in determining your fertility window. Use this oral thermometer every morning to figure out when ovulation is most likely.

The information is displayed on a large, easy-to- read LCD screen. The accuracy of the thermometer's readings are proven accurate by the FDA. The technology was tested and certified in an International Organization of Standardization (ISO) facility.

Pros

  • Soft tone indicates when “peak temperature” is measured - great for fertility tracking.
  • Clinically tested for accurate readings.
  • Takes temperatures orally.
  • Produces a reading in less than a minute.
  • Tests basal body temperature to detect possible ovulation.
  • Memory function recalls the last temperature measured.

Cons

  • Tip of thermometer may easily break if the device is dropped or mishandled.
  • No back-light may make it difficult to read temperatures in the dark or in low light.
  • Temperature indication beeps are very quiet - may be difficult to hear, especially if measuring
    temperature vaginally.
  • Buttons on the thermometer are small - may be difficult for people with large fingers to use.

What is a Basal Thermometer? What is Best Basal Thermometer (BBT)?

A basal body temperature (BBT) thermometer measure your body’s temperature at rest. Ideally, this temperature would be measured while the subject is sleeping.

However, it’s unlikely that you can take your temperature while you're asleep. So, basal
thermometers are best used first thing in the morning.

Using a basal thermometer, you can get a truly accurate measurement of your body’s
temperature.

Who Uses Basal Thermometers?

While basal thermometers can be used for everyday medical applications, they’re actually
designed with a much more specific purpose in mind.

People who want to start a family often use BBT to help determine when a woman may be her most fertile. This is also referred to as tracking ovulation. Knowing when a woman is most likely fertile can lead to successful impregnation.

This information can be especially helpful to couples who are having trouble getting pregnant. It may also assist women who have potential health risks associated with pregnancy.

If you or a loved one are trying to get pregnant and start a family, be sure to consult your doctor. While a basal thermometer is an essential tool in charting fertility, only a medical professional can help you safely have a child.

How Do You Use a Basal Thermometer to Track Ovulation?

A woman’s body temperature increases a day or two before she is most fertile. Using a basal
thermometer, a woman can chart her BBT. Charting this information may help a woman predict her ovulation cycle.

The data collected by a basal thermometer lets you analyze the best potential times for
pregnancy. Monitor and track your BBT for an increased chance of getting pregnant.

How Do You Use a Basal Thermometer to Get an Accurate BBT Reading?

Here’s the steps you should take if you want to get the most accurate BBT reading:

  • Measure your temperature the moment you wake up.
  • Take your measurements at the same time everyday.
  • Stay in bed. Don’t move around before getting a reading.
  • Don’t eat or drink before or while measuring your temperature.
  • Get at least three hours of uninterrupted sleep the night before.

If you’re using an oral method of temperature taking, also make sure you:

  • Keep your mouth closed throughout the reading.
  • Don’t eat, drink, or brush your teeth before the reading.
  • Make sure the thermometer’s tip is placed on the roof of your mouth, at the top of either cheek.
  • Continue taking your temperature up to a minute after your thermometer indicates it’s done working.

It’s also important to be aware of factors (aside from ovulation) that may increase your BBT.
These could include emotional stress, an infection, or lack of sleep.
