Hi Neville I have never experienced your situation with the ph meter - immediately thought of the calibration liquid as the possible culprit, however you rinsed well so cannot make any comments - I use either the TDS meter or the PH meter however I never put what I have tested back into anything this goes down the drain - so maybe there is some chemical reaction with some deposit of some sort which was not apparent at the time. Agreed with your statement about what you produce, I feel the same way about mine !!!! Take good care Sandee🐬 Attitude is everything !!!

Due to recent comments here regarding pH I thought I'd play around and test again with another batch, and within minutes the water turned milky...WHAT THE...??? I knew what was coming next, that dark spot in the centre of the bottom of the vessel the next day. I dug deep into my memory bank and remembered I used a pH meter previously, but like an idiot I returned the test sample back into my brew water prior to starting the brew process - BIG mistake seemingly. On contemplating events I came to the conclusion pH meters somehow contaminate water. I dumped that entire batch down the sink, only about 1200ml, cleaned the vessel out with paper towel and started again using DW straight out of the bottle - perfect, clear and as it should be both during and upon cessation of the brew process. I did however test the pH of the DW out of the bottle, and of course tipped that sample down the sink rather than returning it to the DW I intended to brew, I also tested pH in a batch of EIS that's been in storage for a while. I did calibrate the El Cheapo EBay pH meter according to instructions initially, and then rinsed it several times with DW hoping everything was 'good to go'. Now, I had some samples tested several years ago at an Industrial Complex laboratory, those EIS samples returned readings between 7.4 and 7.8, besides other results I wanted, in a clear, a yellow and an amber or tea coloured solution. I had this mornings batch tested, and an older sample, plus the DW I used for this mornings batch. They used some computer program and ancillary equipment for testing purposes. I labelled them 'A' and 'B', 'B' being this mornings fresh batch, and just took the bottle of DW to them. My DW test out of the bottle with meter for sample 'B', this mornings sample = 6.7 Their test on same DW using their equipment = 6.7, all seems well. I didn't test or document pH of DW in sample 'A' which was an old batch of EIS, but their test on that sample returned 6.8 Sample 'B', this mornings fresh batch returned 7.0, what it will be in a few weeks time I have no idea? I realised this morning that the measuring cup, and the syringe, and the little circular thingy they inserted into the machine they used could have had *anything* in them prior to my tests being performed? I also understood DW would/could vary in quality from batch to batch. This can/could also affect pH readings. Unless one is looking over "someones?" shoulder and ensuring everything is as clean and contaminant free as is possible there is not much point in testing for anything, anywhere? All these facilities and the people working in them have no understanding our product, hence they would not be as pedantic and methodical with things as we would like them to be. So, I'm back to square one in not trusting anything or anyone other than my own visual observations of my product, and my own determinations on same. I have not been disappointed yet, and am satisfied with the quality of my product. I think people can trip up with all the, let's say, "pedantics" of this stuff. I'm not a happy chappy anyway, I'll just stick to what I've been doing for years and leave the rest of it for someone else. If it looks like a quality product, behaves like a quality product, remains visually like a quality product and is seemingly as efficacious as a quality product...Then it *IS* a quality product <g>. When my better half wins that XLotto I may invest in my own personal laboratory, and get someone who knows how to use it to test stuff for me <g>. What we would like and what we can get are two entirely different things. P.S. As a general question for anyone else who may wish to contribute an answer...Why do pH meters seemingly contaminate water? N. Subject: Re: CS>Electrode cleaning?

I forgot to ask about your strange phenomena and how it turned out. So it was never really resolved? Cèst là vie!
