Where to get pink coolant and how to test level of coolant protection

[KJF]

Is the Toyota dealer the only place to get the pink coolant for 2010 Prius?

Will my old testers for the green kind of coolant work for the pink stuff?

I have found some Toyota fluids including coolant at higher end automotive supply chains, but the prices were a little higher than the dealerships.

I just checked my coolant in my older prius, I've changed it once and the coolant comes already premixed 50/50 ( grrrrrrr) anyway I checked my coolant with a little pocket coolant tester with the float balls and only had one ball floating which on the side comes to 20 F. I decided to check samples in my freezer, turning it to max cold I put in some antifreeze , both from car and fresh from the jug into little caps, and a few drops on the bottom of the ledge of the freezer. Testing with an infrared thermometer I had 1 degree Fahrenheit, and no traces of ice. Will recheck in morning, its been an hour. I did an online search for the accuracy of pocket coolant testers and did not read anything I found helpful.
I'm concluding 1 degree F is good protection for the midwest/central , and that the pocket coolant tester that I have does not accurately test the coolant. You can check the dealership on this. Mine is out of warranty.
