ACT In Situ pH Sensors Customer Needs and Use Assessment.............................................................................. 8
8. Which of the following common measurement instrument types apply to how you use pH sensors?
Other. Please describe briefly. Comments included narratives for applications the respondent felt were not easily
covered in the survey’s choices, although one application was decidedly covered as “depth profiling.” One user
specified in-line measurement of pH within mesocosms. Another indicated pH sensors used while underway
on an AUV. Finally, three users specified more bench-top, laboratory measures for separate samples collected at
depth and for general lab analyses for measuring pH of seawater and bodily fluids. While each of these replies
could have been shoe-horned into a category above, it is far better to document how pH sensors are actually
used. The main point is that in situ pH sensors are clearly used in a number of ways.
