Re: [Distillers] Re: pH testing methods
- Hi Knarl,
The PH meter that I use does not instruct the user to keep the tip
stored in buffer solution, my understanding is that you will get a
longer probe life and less calibration would be required if you do
keep the tip in buffer solution.
My experience with my meter suggests I don't need to do this.
Buffer solution can be bought from almost any Aquarium supplier.
There are different types of solution (eg ph7.0 - ph4.0).
The price can range from $10 to $20 so shop around.
I normally use my meter to test the sparge water for my all grain beer mashes.
I usually calibrate (ph 7.0) every 2nd batch which equates to once a month.
To calibrate is a simple turn of the screw while in buffer solution,
takes less than 5 mins.
I test the sparge water when it is 55deg C (before it hits 75deg C).
The reason being is that my meter has a max threshold of 55deg C.
