Hello all i recently purchased a cheapo digital PH meter on ebay. The manual says it comes pre-calibrated. My question is can i calibrate this meter without using the store bought PH calibration solution 7.01? I bought some FIJI water that has a PH of 7.5 can i just dip it into this water and adjust it to 7.5? Any input would be great.
Thanks
