A bigger Geratherm - NOT the XL!

Ok, so FYI for everyone looking to buy a bigger glass thermometer:

Geratherm Classic is your run-of-the mill European glass thermometer

Geratherm XL is NOT bigger! It just has a case that magnifies, so it just LOOKS bigger when you read it.

Geratherm Basal is actually bigger than the classic. And then it also comes in the magnifying case.

I don't like the Geratherm or European style thermometer. Only because the bulb is too thin, and it doesn't extend much beyond the thermometer base. A custom-designed vintage "style" glass thermometer with a large pear-shaped bulb would be great, but nobody produces them anymore, and I truly doubt that anyone would invest the money to create them, with such a limited market.

@JJM yes I agree. Also, there are corners on the thicker part that are not very rounded. The older '80s thermometers have more gradual increase in width so the thick part slides in easier. I still have an old thermometer in a metal case similar to what mom used.

You might look on e-bay or other secondhand websites for one, they are available regularly.

Anyone find a large animal thermometer appropriate for human rectal temps? Equine or cow thermometer might work. Small animal vets use standard or infant size.

I saw something like this at Walmart. I was looking at the thermometers where people come to pick up their meds and saw them in a bigger box. I am planning on buying one later for rectal temperatures.
