New Grower Calbration of a new ph meter

[AnonymousGrower2]

So i get my ph meter and it tells me to use tap water , and to switch on meter and check the ph,this is where im confused it also says tap water should be @6.9 ....so take the small screwdriver it came with and adjust the reading till its 6.9......surely tap water varies in ph all over britain ,im in scotland where our water is very very pure......confused ??

You will need some proper calibration solution for the meter.
Check to see what you need for that model.
It's the only way to be sure...

Stick ph meter to vinegar. Ph around 2-2.5

Green all the way.
