Looking threw the new Van Dykes catalog on page 246 I see they now have listed a digital pH meter. I have been thinking about picking up a meter and was wondering if anyone could give me some feed back on the Van Dykes meter or even another brande that they are happy with. Also as you know they have to be calibrated with a standardization solution like pH 7.0 and 4.0, for fine tune adjustment. So I also will need a dealer for the solution. Any and all thoughts would be great,and thank you for your time.

If you check the internet for labratory supplies you should find what you need. There may even be a used equipment dealer that has a good ph meter for not alot of money. Call Van Dykes and see if they carry the buffing solution for the meter they sell. If not Hatch is a major anylitical chemical testing equipment supply company they carrys the ampules to make the ph 4 buffer solution. The direction come with them but remember to use distilled water. Keep the H head in this solution then rinse in clean distilled water before you place it in the solution you want to check. Then rince the head off before placing it back in you buffer solution at ph 4. This will keep you from carring over either way and give you a better reading. Good luck Paul
using papers and ranging the solution is far more acurate and simple as well as cheeper

Don't waste your time and money on a meter. Buy the papers. More importantly I think is a salinometer for your pickle and they are really cheap. The papers are very accurate.
and have no experience with ph meters but i know they sell them at earl mays and some ag supply stores.
I never did like the papers when I did my own tanning. Here's one available online. http://www.professionalequipment.com/xq/ASP/ProductID.508/id.6/subID.263/qx/default.htm
an experienced tanner told me I'd end up going back to papers, and he
was right. I had 2 different meters, and kept them calibrated,
and they were no more accurate than the papers. I'll take papers
any day.
If you're going to be measuring pH's in the range of 1-2 you don't want to calibrate with pH 4-7 buffers.....
for you paper users a tip: Put a drip of solution onto your paper as opposed to dipping the paper into the solution. You'll leech out the chemical indicators the later way..
I have had a meter like the new one in Van Dykes for years. I like it. Find it easy to calibrate.
