Aap kafi achi information dete ho . Bas kisi kisi videos me aap jab bolte ho oos samy ye zingoor ke jaise aavaj irritate karti hai.

[@mangeshvartha2820]

Sir aapne ph ki range batayi lekin minimum range aur maximum range kitani chahiye ye nahi batayi. plz sir water ph range mini & max

[@voiceofkayani5419]

Dear,
Plus minus range depends on method...
Little bit vary...
Normally +/- 0 2 hoti hai and Kam bhi....
Water ki pH 7.0 hoti hai normally depends k water konsa hai.
Water pH is pharmacopeial

How to perform slop calculations pH meter??

[@voiceofkayani5419]

It is calculated by instrument software it self....
But manually is little how difficult...
You should calculate valtage difference between 2 buffer's and divide it by difference of 2 buffer's ph

[@shyamthakor6617]

Sir can you explain important of mV in using of pH meter

[@voiceofkayani5419]

mV has very important role in measure of pH in any solution.
pH is potential difference between sample and reference measure in mV. Which is used to calculate the pH of sample via calibration curve. So Mili volts has very important role in pH meter during pH calculation.
