I've just went to calibrate my ph tester and its all over the place, this is the first digital ph tester i've had though and the instructions were crap and didn't give you much info on what to do with it. with the buffers, do you only use them once to calibrate it then chuck them and use new solution or what? I'm trying to calibrate it and its not givin me the right readings, eg i used the lower ph solution, calibrated then done the higher one and calibrated that, tried it on tap water and its no comin up at 7.0, which is what my tap water is. anybody with any info would be appreciated, sorry if i sound like a numpty/doughball but need to get this sorted asap!! when i first got it i used the calibration solution and put it back in its bottle as it only came with a wee bottle each of the stuff, was that wrong or what?? someone help me please!!
