Good question.....I too have looking, my local WM has 2...they have a "pump type" that has a bulb on it that sort of takes a sample and has a mechanical meter that lists the protection....
Then they have a simply "ball tester" that has little floating balls......
http://www.doitbest.com/Antifreeze-Custom+Accessories-model-46664-doitbest-sku-574168.dib has the ball tester for 99c
or the bulb type http://compare.ebay.com/future/220372984266?var=svip<yp=AllFixedPriceItemTypes&rvr_id=157914499535&crlp=1_263602_304672&UA=WVS%3F&GUID=e0ef5c7212b0a0aad4d71b97ff84f605&itemid=220372984266&ff4=263602_304672

I don't think the floating ball style work for all types of anti-freeze.
I found this one. A local tool supply hose carrys this brand, so I was hoping its a little cheaper.

I have the one with the dial in it.They are easy to use and I think you get better results from them.
It should be noted that the mentioned tester should work with any antifreeze as long as the base is ethyl glycol. The main difference between all the various antifreezes is the additives, not the base chemical that prevents it from freezing.

Anything (not just the eth glycol) dissolved in the solution will lower the freezing point so the additives will affect the freezing point depression. You could dissolve a ton of table salt in the water and it would prevent it from freezing. I assume though most antifreezes are similar enough that you would get a similar molality for the specific gravity testers to be in the ballpark.

What about corrosion protection, can the testers measure that?

You need test strips for that.
