Safe, Eco-friendly Temperature Charting
An innovation in preconception and fertility products, the 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, which is critical in BBT charting. This safe, easy-to-use basal thermometer comes with its own magnifying lens built into a no-break carrying case. It measures temperature in degrees Fahrenheit.
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.

- Contains absolutely no mercury.
- Ultra accurate - certified to exceed ASTM standards.
- No-break, easy-read magnifying case.

What is Basal Body Temperature?
Basal Body Temperature (BBT) is the lowest temperature attained by the body during rest period or sleep. It is measured immediately after waking up and before any physical activity has been done.
How Does Tracking Basal Body Temperature Help to Conceive?
When women ovulate, there is an increase of one-half to one degree Fahrenheit (or one-quarter to one-half degree Celsius) in BBT. Daily Monitoring of BBT can be used to estimate the day of ovulation. Using a Basil thermometer and the attached chart you can track when the best time to try and conceive is. This thermometer measures temperature in degrees Fahrenheit.
