Rectal Thermomer with Longer Mercury Tip

I’ve never seen a rectal thermometer with an elongated mercury tip. This looks more like an oral thermometer — but I ordered one anyway just because I’m curious and I love the yellow glass with the red triangular tip at the other end.

Anyone here used one like this as an adult?

Naturally, I’ll take my temperature with it as soon as it arrives & add my review to this thread.

The traditional European thermometers had long tips, that didn’t look like they were inserted very far up the butt. They don’t look much different than the American vintage oral thermometer.

The tip does not look all that long. I think that it is indeed a genuine rectal thermometer. Enjoy!!

I have one. Yellow, w/,a somewhat longer bulb and a red triangle no roll top. It also says hi a on it but does not say rectal.

Just posted a few pics of this thermometer in action. Sorry my photos are all so similar. I’m multitasking and trying to be as discreet as possible, which severely limits camera angles. My temperature this afternoon was 100.4.

@JJM Long tip and then wider "body", which is not meant to be inserted. Except that some parents would partially insert it.

Geratherm type thermometers used in Europe have an insertion guide to prevent over-insertion although it's fun to ignore the guide and slide it in further.
