seeking PH Meter recommendation...

Hi.

I'm seriously thinking about getting a PH meter ... Most of the research I found on the web was a bit out of date

I need something relatively cheap Accuracy around 0.05 Probe long lasting Easy calibration

Preferably available in Canada, or on Ebay. (If it's not for Canadians, no big deal, someone will send it over here...)

Thanks for your ideas

Stef, Montreal.

Stef, Take a look at the Hanna pHep 5; it's hard to beat for the money. It's usually $70-80 USD. I got mine from Grainger.com but most wine shops and any good chemical supply house will have them. It meets all of your requirements.

To calibrate it consider Hydrion capsules. The are added to 100 ml of distilled water to make the buffer. (Those I have never seen in a wine shop, you may need to get that at a chemical supply.) It's the cheapest way to make accurate buffers that I know of unless you are a chemist.

May I recommend:

It's the one I've use- I've benchmarked it next to our lab meters and it's 'close enough' with calibration.

Pick up cal solutions from piwine- more of it and cheaper- and do a 2 point cal.

Jason, I tried that meter, it's from Hanna also. Mine was not very good but maybe the probe was just bad. Mine drifted excessively and was never very repeatable. I'm glad yours is OK, I may have just had a dud.

I do the 2 point cal on every batch- my probe seems 'depth' sensitive to the pH. Which means it's not the best, either.... but it's repeatable in the range t hat I work. I keep the buffers nearby and test between, during, and afterwards and adjust for drift that way.

I found that the 'atc' is very poor on that unit. I guess I'm spoiled on my old lab equipment...

That looks like a great deal. The price is very good.

Joe,

Bouchard Cooperage is another option for small barrels. For 24 month air dried French (Allier) Oak they are as reasonably priced as I've seen. I bought 2 of their 57L barrels last year and I'm very pleased with them. I have no connection whatsoever to this company. Shipping to SE Pennsylvania added about $45 to the price.

Hi Seb. Well I want to thank you for your PH meter suggestion. If I ever get hooked into wine making I might even joint this association you presented me....more questions for you if I may .... I would primarily use a PH meter while doing a TA analysis. I read it's the best way to be precise with red wine.... I looked at your TE-25-4225 seriously , soo cheap...hehe Do you believe this meter would be practical in that matter? The reason I ask is one, I'm ignorant...( a month ago I didn't know about TA, PH...) and second I have actually never seen an TA test kid... and therefore I assume the probe on the TE-25 might be to big to fit into a TA kit... Am I making any sense here? .Also does it make sense to buy a model with a replaceable probe? The TE-25-4225 at a bargain price is probably not a replaceable meter....but again, I dought one could purchase a new probe for under that price....

Everyone welcome....

For the size - this looks pretty much like the Hanna pHep 5 that was already mentioned in this thread, I've got one of those. I do the pH and TA measurements in plastic pill dispensers, you can get those over the counter in any pharmacy. They're just wide enough for the meter to fit in comfortably and for the 15 ml of wine to cover the probe and then some - pretty much perfect for this.

They're also really handy for making up sulfite or sorbate solutions to add to wine or for holding wine samples when doing ML chromatography test, etc., etc.

If you are talking about those 30 ml medication cups that is what I use too and I use a pHEP5 too.

Here is a link to a picture, you see these used in hospitals to dispense liquids or oral solids at the bedside..
