The OT20 Thermometer is perfect for couples or women interested in using natural methods to increase their chance of pregnancy. It is as easy to use as a conventional body thermometer and can take both oral and vaginal measurements, so you can pick the best method for your needs.

How Does the Ovulation Thermometer Work?

A woman's temperature can be used to predict ovulation as it tends to be lower at the beginning of the cycle, but increases once ovulation begins. The Beurer OT20 thermometer and the Ovy App it is provided with can help you track these temperature changes so you can determine when are are likely ovulating.

How Do I Use the OT20 Ovulation Thermometer?

The OT20 Ovulation Thermometer can take your temperature either orally or vaginally (you should only use one or the other once you've chosen your preference). It functions very similarly to a standard thermometer, however it can typically detect smaller changes in body temperature. Once your measurement has been taken, the thermometer will produce an audible signal. For more information, take a look at the instruction manual at the bottom of the page.

How Accurate Is the OT20 Ovulation Thermometer?

Like most basal thermometers, the OT20 offers more accurate readings than standard thermometers. It is accurate to ±0.05°C at 35°C to 38°C, and ±0.1°C in remaining measurement ranges, and will display your results to 2 decimal places.

How Do I Take Accurate Readings?

To get the most accurate results possible, we recommend taking your basal body temperature every morning before you get out of bed. You can then use the Ovy app, to track your results, learn more about your cycle and plan your sexual activities.

What Is Ovy Cycle Tracking App?

The Ovy App is designed for women and couples planning children, and comes free with your OT20 thermometer. With this app, you'll be able to track your entire ovulation cycle and use your smart phone to monitor it at any time. The app can be downloaded from the Apple App Store and Google Play.

Is Using an Ovulation Thermometer a Reliable Method for Family Planning?

Ovulation can have an affect on your body temperature, but there are also many other factors that can contribute to fluctuations. Therefore while ovulation thermometers can increase your chances of getting pregnant, we don't recommend you use them as your only form of contraception.
