Safe, Eco-friendly Temperature Charting

An innovation in preconception and fertility products, the Fairhaven Health Glass Basal Thermometer is a mercury-free and non-toxic alternative to mercury thermometers, that is designed specifically for Basal Body Temperature (BBT) charting.

Our glass basal thermometer is family- and earth-friendly, yet is certified for accuracy – critical in BBT charting. This safe, easy-to-use basal thermometer comes with its own magnifying lens built into a no-break carrying case.

This glass basal thermometer contains absolutely no mercury, using a safe, liquid alloy instead. Concerns about mercury have been featured prominently in the news, and many states are requiring that mercury-containing thermometers be recalled by manufacturers due to toxicity and related health hazards, particularly for pregnant and trying-to-conceive women.
