Description
Non-toxic glass thermometer for BBT charting.
The Mercury-Free Glass Basal Thermometer is a safe, accurate, environmentally-friendly alternative to a mercury basal thermometer designed specifically for Basal Body Temperature (BBT) charting.
This easy-to-use glass basal thermometer is ultra-accurate and certified to exceed ASTM standards—a most important feature for BBT charting.
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.
