6.3g thermometer with -40f to 120f (-40c to 50c) range

Exposed glass tube? ie, breakable?

"Exposed glass tube? ie, breakable"

I should have mentioned that it is in a clear plastic tube. I wouldn't fear it hanging from my pack.

No batteries!

Dale,

Do you have a way to verify its accuracy claims? If it meets those specs it's tough to beat.

I just got it, so I'm testing as I go.

I was trained as a photo technician and have quite a bit of experience with lab thermometers. I had a Kodak Color Process thermometer that was about a foot long and accurate to 1/8°f between 68°f and 104°f.

They all vary and 2°f isn't stellar, but certainly good enough for my use in hiking. I'm putting this a step up from a zipper pull version that tells you what you already know: it's hot or it's cold. It is made for commercial food storage, so a basic level of accuracy is expected. It would be useless in direct sun.

That clip on the top swivels and it's made to hand from the wire racks in a refrigerator. It has a hole in it and I plan to put a loop of light line through it to hang it from.

Hmmm. I'm collecting stoves, some lanterns, now thermometers I guess too. I got a nice cooking thermometer over the winter, has a case the probe slides in. Would be nice to get a H/L one though for giggles.

The one time temperature accuracy is important is freezing – you want to protect your water from freezing, especially if it's inside your Squeeze filter.

(Probably 2 F is good enough)

Put your thermometer in ice water. As much ice as possible. Put thermometer in the middle of ice away from edge. Let it sit there for 10 minutes. That should be good to 1 F or 1/2 F.

I just write on my thermometer what the freezing temp is for that thermometer.

If I have containers of water un-protected, at 30 F, they don't freeze. 28 F you start getting ice crystals, the cap can freeze onto the bottle. I can manage 20 F by putting on the ground and covering with brush/clothing. Maybe have to heat up some water in the morning and pour it back into the container. Make sure cap isn't on tight.

Nice find. You always find the good stuff.

I have that model in my fridge. Didn't think about taking it out to compare it to my zipper one…

Wow, 0.7g more. That's like one paper clip :)

Nothing like a good find that you already own!

The "Vertical glass tube" mentioned in the product description most likely refers to the thermometer itself, not the transparent cylindrical enclosure

No batteries!
That is a plus … and a classically simple user interface to boot! Shouldn't need much of a user guide … if any.
