Bendix recommends a tester that heats the brake fluid to determine the correct boiling point. Using a boiling point tester is the only accurate way to test brake fluid performance."
Since you do not know what brake fluid your conductivity testers were calibrated to there is no way of knowing if the results you are getting are accurate.

OK. I'm convinced my cheap-o tester(s) are likely worse than simply assessing based on known age, appearance, and brake performance. Ive had enough strange results over the years: better off simply not using them.
I just sprung for a real boiling point measurement tool. On the off chance folks are curious what a real measurement produces, I'll update once I have better data in a week or so.
Thanks everyone!
