Re: Another noob question

maybe you might find some of these locally, but you can always send for one if not.

Re: Another noob question

They are all flimsy and apt to break. Except the plastic ones which are just plain no good.

Look for one with a fine scale on it. There's a company called Freas which makes a ridiculously fine scaled version: 1.250 to 1.275 in 0.002 increments. This is 'overkill' in my opinion.

There's also a type with built-in temp compensation, sometimes called a "thermohydrometer".

Here's a place with some examples (not to be interpreted as a recommendation):

Should give you some idea what to look for (although that site is short on specs). You ought to be able to find one locally and for reasonable money.

Oh; don't ask for a "hygrometer" or you'll get a device for measuring ambient humidity.

Re: Another noob question

That bottom one for $10.34 looks exactly like the one I got at Checker Auto for $4.99.

I'm gonna put some shrink tubing around the ends of the glass tube. It only takes a light bump there and they split up the side.
