Title: pH Meter - Recommendation?
Post by: aceddu on July 12, 2009, 01:31:10 AM
Hello to everyone! Before I go any further,I'd like to say "thanks" to all.On this site I have found answers to many questions I've had regarding cheese,and the equipment required to create it,and the thoughts/ideas that lead me in new directions.I am new to this site,but not new to cheese making.I have been making cheese for a few years,and have been doing so without the use of the technology available to me.Which leads me to the reason for this post...I am interested in finding a utensil that would perform well in both cheese making and the process of making salumi(cured meats).I am curious as to how well(accurate)the ph strips would work vs. the low-cost ph meter...vs. the higher priced ph meters.
Anybody have any opinions to share,pros/cons of both...working with both cheese and meats? I'm looking forward to the responses.
  Thanks...Mike

The main difference I have found between the strips and any meters is raw accuracy. The strips just are not that acccurate.
the el-cheapo pH meters are way ahead of the strips in accuracy, but I have two problems with them.
1> not accurate enough to produce consistant results, in that they will typically measure out to the tenths of a pH. (good ones will give you another decimal.) (why?  I stop cooking my cheddar at pH 6.15.   not 6.1 or 6.2)
2>They will break easily and soon.  I went through 2 el-cheapos prior to getting my current rig.

My current pH meter will measure the pH of my cheesemilk, my curds, my finished cheese, my wine, my spit,  and I would have to assume your cured meats   ;D

I use this pH meter. Extech EXSTIK PH110 (http://www.amazon.com/Extech-EXSTIK-WATERPROOF-REFILLABLE-Product/dp/B0012W2NWS/ref=sr_1_1?ie=UTF8&s=hi&qid=1241571416&sr=8-1)


You can find a discussion of this, and other pH meters here (https://cheeseforum.org/forum/index.php/topic,1071.msg8643.html#msg8643).


Good Luck.

Wayne -

Is that the person you bought your ph meter from? Does it include everything you need to get started, or do you also have to buy solution? I will be purchasing a meter in the next few weeks.

Here is the manufacturers web site.

If you click on the picture, it will take you to their web site and show you all the accessories.
You can buy this here, or on Amazon. 
I have attached the meter's datasheet.

Wayne - I've read about this meter for the past few hours,and it looks like a winner.It appears to be very simple to use,and the ph readings carry to the 2nd decimal place,much more accurate than the strips.I searched ebay U.S.A. and found one for less than $100,
so I went ahead and purchased it.I hope to use it within the next 2-3 weeks. Thanks for your help !

So Most of the recipes i read control ph through time and heat. They do not list a specific PH level. Is there a  recipe book that lists ph levels, or do you have any general guidee lines.

The U Guelph site has some specific guidelines.

If you look around, you will find some recipes like those listed at Peter Dixon's (http://dairyfoodsconsulting.com/recipes_cheddar.shtml) Site that reference pH.

Danged if I can find it on his site again but Professor Hill of U Guelph gave me promission several years ago to reproduce his information on "Cheese Families" on my website. If you look closely on the tables you will find  a lot of info on pH and other helpful info based on the type of cheese you are making. This was the first current printed guide I used for making cheese and I find it very helpful.

Also, the CHR Hansen Cheese Making Guides (https://cheeseforum.org/forum/index.php/topic,593.0.html) have some pH or Titratable Acid numbers.

Thanks LB no wonder I couldn't find it I coverted it into a table and was looking for the table - DUH!

I have been working on a new table of pHs and quick ref recipes but it's not done yet. I am an Excel addict too.
