The Effects of Temperature on PH Measurement
knowledge.reagecon.comthe correct buffer is used. Meter manufacturers generally specify specific pH buffer types to be used for calibration - for example some pH meters can be calibrated using technical pH buffers or DIN/NIST buffers (values specified at 25°C) (11). Use of the incorrect buffer type can lead to inaccurate calibration and hence incorrect pH measurements.

Acid Rain Experiments - Cornell University
ei.cornell.eduAcid precipitation is defined to have a pH lower than 5.6. In New York, the average pH of rainfall is 4.0-4.5 and individual storms as low as 3.0 are not unusual. Freshwater lakes commonly are slightly basic. pH's in the range of 6.5 to 8.2 are optimal for most organisms, and below 5.0 is lethal to many fish species.
