I purchased a new pH pin about a month ago I purchased the Apera pc60, it worked great for the first three to four weeks and now I've noticed that the reading is starting to take a lot longer to get where it needs to be sometimes even 2 to 3 minutes I've never let the probe dry out I've always kept it in the storage solution like it says anybody have any ideas what I could be doing wrong or is this just a junk pen
