The Ultrapen PT2 pH meter was delivered today. It is a very successful device. However, if you want accurate measurements, you must clean the probes before first use. I recommend a slightly acidic solution for cleaning. Difficult to clean with normal water. In addition, if you do not use a cleaning and protection solution, you will get different results in each measurement. When you pay attention to all these, you will get faster and more accurate measurements.

Despite following instructions and frequent 3 point calibrations, this ultrapen is wildly inaccurate. I was hoping to save time and field test water for pH but this is too much of hassle for readings that aren’t even close.

I bought this after using a Myron L Ultrameter II for a year with amazing accuracy. This Pen falls far short from their other item.First off it needed calibration right out of the box unlike the ultrameter. Even after that I got different reading from the same sample 2 whole points off....not 0.2Second this item takes a long time to give a reading. 30 seconds minimum. For almost $200 this thing should be perfect.

Readings are very delayed and sometimes inaccurate. Not really a fan.

We use these to test our machine tool coolant and they work very well, just wish they would hold up a little better, but that is more of an issue with the coolant than the pocket tester.

Best pH pen I've used so far. I've tried hannas and oaktons, but like this one better. The pen takes a few seconds to deliver a reading, but it takes and holds a calibration well and feels really sturdy. If you are taking a ton of readings the lag may be annoying, but on the plus side you don't end up staring at the pen waiting for the reading to stabilize.

I've been wanting this pen for a while now and its working great so far. Calibrating it was a little confusing at first but I got it down and it's reading accurate I use the ph strips as backup sometimes so I know everything is good. I like that I just buy probs now as replacement instead of new pens. No more bluelabs lol.
