The Fairhaven Health Digital Basal Thermometer allows a woman to determine her body temperature for basal body temperature (BBT) charting purposes. Designed specifically for fertility charting, the FH basal thermometer combines pinpoint accuracy with safety and ease of use.

Our digital basal thermometer provides temperature readings to 1/100th of a degree - perfect for fertility charting and predicting ovulation. Because consistency and accuracy are critical, the thermometer also offers helpful charting functions, such as digital memory recall and a peak temperature indicator.
