REVIEW
It's a good way to read PH. I can't stand trying to read the colors and maybe off. the blues all look the same. This meter was expensive, but what in this hobby is not. If you want a good instrument, Then this is the one.

REVIEW
This tester is very easy to use, but the calibration instructions take a long, frustrating period of time to figure out.

REVIEW
This product works great, but it is very hard to figure out from the directions given how to calibrate it. The directions are not very clear and too abbreviated. That is my only complaint. Also it tells you you have to buy certain solution to store it in and they don't give you any, not even a pa...Read More
