Seems like a good product, but the instructions say to keep the probe wet? Don't know how I'm supposed to do that when it says not to store it in RO water. I haven't kept it wet, but it seems to be working well.

Upon opening calibration is easy with a little screw driver(provided) adjust the back. Make sure though you buy some calibrating solution though. I bought two different calibrating solutions a 7.01 and a 10.01 just to make sure the Milwaukee pH600 pH Meter Pen was accurate and it is. I have however already had to recalibrate it was off by .5 and I dont remember dropping it or banging it. I just want to make you aware of that. Seems like a good product.

This makes quick work of getting your PH value. I have found however that I have had to re-calibrate it more than once which brings my concern of how accurate it really is.

I bough this pen pH meter to be able to test my nano tanks. As soon as I opened the package I was impressed. Super easy to calibrate and use. One of the best items I have bought from Bulk Reef Supply.
