Sorry for the confusion, I was only asking about the slope of the electrode using the mid and high calibration settings so I can check the condition of the electrode after calibration. What Borek said makes sense, I just wasn't sure.
Ultimately I'm trying to achieve the following.
1. Calculate...
Thanks Borek!
Sorry symbolipoint I don't understand that. The formula seems to be common for some meters, I got it from a Hanna manual but it only shows the first example.
Can I ask about a formula for temperature compensation? Best I found is 0.003 pH/ºC/pH but I don't know how to apply that.
Thanks, something like this?
This is using 7.0 and 4.0
pH electrode generated –5 mV in pH 7.00 buffer and +165 mV in pH 4.00 buffer.
165 mV – (-5 mV) = 170 mV
170mv/3 = 56.66mV/pH unit
56.66/59.16 x 100 = 95.8% slope
This is using 7.0 and 10.0

Hi, I'm trying to calculate the slope of a pH probe using 7.0 and 10.0 buffer solutions. I've been searching for hours but all examples use 7.0 and 4.0. I've calibrated my probe using the 7.0 and 4.0 buffers and calculated the slope, then I used 7.0 and 10.0, used the same math for the slope and...
