I've never used it but I know that it's the pretty much universally disliked by the water experts, because at best it doesn't work and at worst it adds a lot of stuff we probably don't want in our beer. Best avoid it.
Yeah I think around 5% is the recommended maximum, but in a pilsner or similar probably less.
I have one of these Voltcraft meters (although I'm pretty sure I only paid about half that price for it). But I also have an el cheapo meter from ebay and they always read very close to each other.
Reassuringly expensive.
Thanks, Argentum. Just checked on Amazon and I think I could afford the replacement probe! Even more reassuringly expensive than Steve's.
I don't think this is a limitation exclusive to Bru'n Water. It's probably practically impossible to predict mash pH with a high degree of accuracy so the best that tools like BW can do is an estimate, but that's usually good enough to get into the correct range. How far off have you been?
You are right, but unless you know that you need it (from alkalinity test or water report) then I wouldn't bother.
Steve if i go by the yellow one(pH meter) then i am quite a way off it is showing 4.7 this is after being calibrated to 6.8 & 4.1 in solutions
