Ph Values At Various Temperature - Hanna Instruments HI 8510 Series Instruction Manual

pH VALUES AT VARIOUS
Temperature has an effect on pH. The
calibration buffer solutions are effected by
temperature changes to a lesser degree than
normal solutions.
Please refer to the following chart to perform
the pH calibration:
TEMP
°C °F
0 32
5 41
10 50
15 59
20 68
25 77
30 86
35 95
40 104
45 113
50 122
55 131
60 140
65 149
70 158
For instance, if the buffer's temperature is
25°C (77°F), calibrate to read 4.01 or 7.01 or
10.01 on the display.
If the buffer's temperature is 20°C, calibrate
to read 4.00/7.03/10.06 on the display.
If the buffer's temperature is 50°C, calibrate
to read 4.06/6.98/9.82 on the display.
