C. Recommendations
21. How important are the following characteristics to you when using pH sensors in the field? Please enter
a value between 1-5 for each box, where:
1 = not at all important
5 = very important
The top 12 characteristics are scored, sorted, and shown in descending order in the figure below:
All other responses cumulatively averaged a score of 2.48 in importance and included 8 categories; however, In-
field maintenance tied with Flow sensitivity for a score of 2.92.
The scores for the remaining 7 categories are:
Sampling interval / frequency, 2.82; Operating pressure / depth range, 2.68; Real-time sensor data display and/
or analysis, 2.46; Packaging, 2.31;Input / output interfaces (e.g., computers, alarms, etc....), 2.26; Automatic
calibration, 2.23; and Off-sensor telemetry, 2.13. No single category stood out as “not at all important.” All
scores were greater than 2.
