I bought one of these ph meters and some buffer solution but I got 4,7,10.
If you look down the page it says:
PH Calibration:
1. Immerse the electrode in PH 6.86(under the temperature of 25?)Standard buffer solution of phosphate and gently shake the electrode.
2. Regulate the trimmer with a screwdriver until the buffer solution value corresponding to the measurement temperature is obtained.
3. Immerse the electrode in PH4.01 or PH 9.18 the standard buffer solution of borax.
4. After about one minute, until the buffer solution value corresponding to the measurement temperature is obtained.
DID I just screw up, or will I be able to calibrate it?
Anybody else use this PH meter?
