Good morning,
I hope I am correct in understanding you operated previously, or still do so, under the business name of North American Greenhouse Supplies.
I have been making wine for many years and in 1999 I purchased one of your PH systems, the model pHMS. For measuring ph levels in winemaking the system is excellent and helps me achieve top quality wine. In addition, one of my other interests is taxidermy which I have been doing for the past eight years as a part time business.(my web page is hillstaxidermy.com). When I tan skins I have to be very specific with the ph levels, within a range of ph 3.5 to 4.00 or they will not tan properly, and to do so I purchased a second ph meter, the same model, in 2000 which works perfectly for my tanning work.

The reason why I am writing is to thank you for making such high quality ph meters which give me great reassurance and satisfaction. After using all I have done is rinse them well and store them in the ph 7 solution as instructed. They are trouble free, always accurate and I use them at least six time a month, which may not be a lot but is consistent over the past four to five years.
If you ever need a testimonial or reference at any time please do not hesitate to contact me.

Yours sincerely,
Richard
