I went with an Omega PHH-7011 about a year ago as I finally tackling the topic of water chemistry + needed a more accurate way to measure mash pH. This meter is easy to use and works well, but ran into a silly issue last week where the batteries died + I couldn't remove a screw that holds the cover on. None of my usual tricks worked and so I sent the folks at Omega an email asking if they had any tips. Within a day I had a great email from customer service saying they'd be happy to replace the meter free of charge. Say what?
Not only is this a great meter but Omega really stands behind their products. That's worth more than the meter in my book. Highly recommend.
