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 Most of the research I found on the web was a bit out of date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.
Joe
thanks Joe, I will look at this one... Regards
stef
I posted this previously here:
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.
Jas> Hi.
Stef, I'll second Joe's recommendation for the Hanna pHep 5. I've had one for about 2 years now and it's been very good. The price is about as good as you'll find for ±0.05 pH; ±0.5°C (±1°F) accuracy.

thank you Guys
Stef.
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...

Hi Stef, best salutation from an other Québécois :)
I beleive that the best deal on the market actually for this kind of meter is the one at 0,05 accuracy sold at Valley Vintners :
Did you know that there are a provincial association of amateurs winemakers in Quebec ? May I invite you to join us, see our web site at

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

Séb Know anyone with any experience with those 40 to 100 litre Hungarian barrels? They look like just what I am looking for down here...

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 Joe, yes I know a couples of guys who use Hungarian oak barrel and they all seem to be happy with them. I will buy my firs Hungarian barrel ( 56L ) in august. Actually I have a canadian, french and american oak barrel ( all 56 L ) and I want to give the Hungarian a try because they are well made and I heard they are similar to a french barrel in term of oakness and tanin extraction. I really like my Canadian barrel by the way ;)

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....

stef, Salutations distinguees
.more questions for you if I may .... I would
This meter is only $36 so it's the price of just a normal probe. Don't care about the probe with this one, just got a new meter ! This one have 0,03 accuracy which is really nice. You can easely use it to measure the TA of your wine but just be sure to calibrate it first with
7,01 buffer and 10,01 to be more precise. The end point is at about 8,2 pH. Of course the probe is large but you can use a larger container to mesure the pH and then transfer the volume of wine into your graduated cylinder to see what's your TA. This is what I'me doing since many years. I use the unit sold at Valley Vintners at around $100 with 0,01 accuracy. It's a bench top meter and it work very well. St-Pats sell the same unit for much more ! I know Valley Vintners have very nice price on pH meter because they buy directly from the manufacturer while others buy from distributor. So you got one margin of profit less. I firmly beleive that pH meter is the easiest way to measure the TA. But you need at least a 0,05 accuracy to be precise. Take care not to mix accuracy with resolution. The resolution is the number of digit that can show on the display.Séb
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..
