I just bought Checker PH tester by Hanna Instruments and have a question
about calibration kit. It says in the manual that I have to empty powder
in
100ml of water but I heard that you can split capsules up to 15 times.
That's what I read "May enough buffer for about 15 calibrations if you are
not wasteful." Also what water should I use? Can I use 1gal. Jewel or
Dominicks drinking water?



I just went to a Hydroponics store and purchased the liquid PH4 and PH7. No
messing around mixing.
