 Amazon did me wrong February 27, 2010
Peter L. Roca
This product came up on a search for a pH meter on amazon. It certainly does not measure pH. It is a great product for what it's advertised to do, but amazon presented it as a solution for a pH meter, which it is not. I assumed that a conductivity meter would have some sort of pH functionality, and the fact that it popped up on a search for pH meter convinced me.
I realize that I am at fault and I have found uses for it... but I am complaining that amazon's search algorithm lied to me.
 very easy to use and just what i needed February 10, 2010

I got this in the mail and was using it in 5 minutes. I was going to read the instructions, but didn't really need to, it's very straightforward and easy to use. It's waterproof, which is very nice, and has a nice feature that allows you to take a reading, hit the "hold" button, and the remove it from the solution so you can read the meter even though it's not still in the solution. It was much cheaper than other options, and I must say that I'm very pleased with it.

For me, the calibration with a screw driver really put me off. This meter does away with that. You use push bottoms to calibrate the meter and after that its dip and check.
The hold feature is nice, dip the meter in the solution, press hold then remove it for a closer look. Very nice for those of us with glasses.
From what i have seen of this meter, I have to give it 5 stars simply because its well made and works like its supposed to.

I just got into the hobby of hydroponics, and it seemed as though I was going to need an EC meter to keep from burning my plants, so I did a little research and with my budget, this one seemed to fit. It's simple, and easy. It's also accurate, and worked from the get-go. No complaints so far. Just turn on, dip in the water, and it gives you an instant reading.
Works great, easy to use, rugged. November 16, 2009

This thing is a lifesaver for serious gardeners. It's rugged. It's easy to use and it's multi-functional. Oh, and it's accurate. I've tested it against other more expensive meters. Can't go wrong with this. I'll probably eventually get the PH meter made by the same company. You get your money's worth with this tool.
