I'm having a serious problem with my ph meter. I've had it for only a year and I don't know whats wrong. I recently noticed that when I put it in ph reference solution it reads 8.3 or 8.4. And it won't even let me calibrate it in the sution, but it lets me calibrate it in RO and regular water. My RO water comes out at about 7.0 but I still wanna be accurate as possible. I thought it was the ph solution but I got new solution and the same thing happens. The meter I use is a
