Summary:[...]pH was reduced from original value listed in Table 3 to approximately 6.0 by adding acetic acid and maintained for one week during which, probe readings were collected. [...]it was decided to decrease the pH to approximately 3.0 by adding hydrochloric acid and the pH was maintained at 3.0 for one week. [...]the graph didn't show any corrosion trend. [...]it is evident that the ER probe with a 5 mil span works only if the corrosivity of the fluid is high and the data logging frequency is approaching the probe response time.
