Hoping to find a source for accurate glass Oral Thermometers to keep in First Aid kits. (We've all seen the cheap digital versions and the last time we needed ours, the battery was nearly dead, making the whole thing worse than useless.)

I've seen reviews for several glass thermometers that have accuracy problems and "shake down" issues. I won't care whether the adult version is mercury or mercury-free, so long as it's accurate. I'll be happy to procure also (for completeness' sake) a mercury-free pediatric version.

I'm hoping to procure "Cool Tool" grade, heirloom-quality, eternally accurate thermometers, hopefully with a rigid removable sheath/whatever to keep them intact forever.

This one, a solar powered digital thermometer, might do the trick.

Check out the 3Ms Tempa-Dot disposable thermometers. The only trouble is storing them at room temperature or below (including the shipping process).

Galinstan Glass Thermometer

Mercury Free

Thermometer from Wilson Thyroid Products

  • I wonder what the Galinstan Glass Thermometer mentioned above is made from. The description says it is "liquid metal" but "not mercury." I don't know what other metal is liquid at room temperature.

  • I asked a physical chemist about Galinstan. It's known as an eutectic alloy, which in layman's terms is a combination of metals that when combined have properties that are unlike any of the associated metals (in this case, it is liquid at room temperature). It's also much less toxic than mercury.

Thanks Dan and Oliver. I learned something! Sounds like a Galinstan thermometer might be something to try.
