Accuracy and Safety - Mercury-free Glass Basal Thermometer
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.

Answer:
A metabolic thermometer is a basal thermometer. These thermometers are designed to take your resting temperature - so, your temperature should be taken first thing in the morning before eating or drinking.By Rachel from Australia on January 11, 2012

Due to possible PCOS, I read about basal temp monitoring and picked this thermometer: 1. It's mercury free. 2. It doesn't use batteries and is better for the environment. 3. I think digital gives less consistent measurements.
This thermometer is easy to clean, no plastic slip covers needed (less waste!) and full-proof to use. To get the mercury down, I put the encased thermometer in an old sock, and twirl the sock. (Read this online, it works!)
The only con is that it's a little wide and awkward to hold in my mouth at first. But now, it's comfortable.
Lastly, thank you Fairhaven for rapid shipping and friendly, gracious customer service on the phone.

I used it to chart my BBT for practicing the Fertility Awareness Method of birth control. I love the glass thermometer much better than my electric one. Unfortunately, as I was shaking it down one evening it slipped out of my hands and shattered. They are a little expensive, so I haven't been able to buy another one.
Pros:Accurate readings and more aesthetically pleasing than electric thermometers.Cons:Easily breakable. |

I tried a bunch of different basal body thermometers when I was first charting a few years ago. I tried various digital ones, and was always a bit unsettled about it not knowing when the batteries started to die and when the readings became less accurate. This mercury-free battery-free thermometer takes out the guess work and lasts well for years. I have one at home and one for travel, and trust them fully. Glad they continue to be made! I refer all my natural fertility awareness friends to this exact thermometer.
Pros:accurate results in 5 minutes good carrying travel case, very sturdy no batteries, works forever cute and simpleCons:not as fast as a digital |

Good accurate measurements. You do have to shake down the mercury after each use, which isn't specified in the instructions. Old-fashioned reliability.
