Tds meter has no way to calibrated(I suspect that it's fake) , i havent try to calibrate the pH meter, but i did try it and when turn it on, the pH will not stay at constant, rather it bounce back and forth. When measure, I'm not sure how accurate it is, but will try to test it out tomorrow morning at my office with the kangen machine. Just beware when purchase these devices. I had another Tds meter that I've bought in the past, I've test my tap water here in SoCal , it's 290ppm, but with this Tds, it read 115ppm, that's way too low for a hardiness zone.

Easy to use with instruction but I don't know anything about these tests so I'm still a little confused. I hope the numbers are correct.
