Precise Cycle Tracking

This digital basal thermometer measures basal body temperature to one-hundredth of a degree in Celsius or Fahrenheit. It stores the last thirty readings for easy recall and works with the Premom app for manual charting. The purple device is intended for anyone monitoring ovulation as part of natural family planning.

Clinical Accuracy and Alerts

Accuracy is rated at ±0.05 °C or ±0.09 °F. A measurement takes about ninety seconds and ends with a soft double beep so no timer is needed. A fever alarm sounds when a high temperature is detected. The large backlit LCD screen makes the display easy to read in low light.

Simple Daily Use

The flexible waterproof tip allows hygienic cleaning and comfortable oral placement. The unit is not Bluetooth enabled so readings are entered into the app manually. It suits users who prefer a standalone thermometer with onboard memory and do not require wireless data transfer.

Questions about this item

How do I install the battery so the thermometer powers on for the first time?

Insert the supplied battery with the positive side facing the marked contact, then close the compartment until it clicks; the display will light up once the cover is fully seated.

What maintenance or replacement will this thermometer need over time?

Replace the coin-cell battery when the low-power indicator appears, and clean the flexible waterproof tip with alcohol wipes after each use to maintain hygiene.

What limit appears first during sustained daily use of the 90-second measurement cycle?

The battery will deplete before any other component; expect to change the coin cell after several months of daily 90-second readings.
