Title: What pH meter do you use?
Post by: roguejim on June 28, 2012, 08:07:00 PM
I've read Kai's article on buying a pH meter.  I'm definitely in the "under $100 club".  I intend to use it for mash and kettle pH testing.  What pH meter do you have, or recommend for my purposes?  Thanks.

I have this one.  http://www.northernbrewer.com/shop/brewing/beer-brewing-equipment/testing-measuring/ph-measurement/milwaukee-ph55-ph-temp-meter.html

My wife gave it to me for Christmas.  It looks great in the box but I haven't used it yet.

I use the one Kai uses, the MW-101. I have to calibrate before each use (those little recessed dials are very sensitive) but so far, so good. $65 on amazon ( http://www.amazon.com/gp/product/B0009YH06Y/ref=oh_details_o02_s01_i00 )

That looks like the one I have had for a couple years.  It may be time to replace the electrode, because it takes a lot longer to calibrate at 4.0 than it used to.  Probably because I used to test hot wort, not knowing I should have cooled to room temps.
I'm happy with it and use it on almost all my mashes.

You got a better deal than I found.  My new MW-101 was $78 shipped from a seller on Ebay.  It has proven to be a capable and reliable meter for me.

Jeffy - Scale can build up on the probe's electrode and slow the meter from settling on the final pH reading.  Try soaking your probe in a weak citric acid solution overnight.

I use the Hanna Instruments HI 98108 with ATC, $70 at LHBS.

Will do.  Thanks, Carl.

Used to have the MW-101 – when it was time to replace the probe on that I moved the Hanna pHep5.

I'm much happier with the pHep5 – no questions when the bugger is calibrated and no questions about when your reading has stabilized.

Personally, I'll never go back.

I use an OakTon pH Testr2, which has been discontinued.  I got it originally for testing rain water pH long before I went to all-grain and started testing mash pH.

I use the same meter.  I'm very happy with it.  I'm also confident with the results it gives.

I use the MW102.  I haven't had any problems with the automatic calibration.  YMMV.

What do you guys think of this deal/meter?  Someone at Hanna recommended it to me.

Spend a few extra bucks and get the one that goes out 2 decimal places.  This is the one I've got and I love it.
