A delivery device such as an infusion set or patch pump is configured for delivering a pharmaceutical agent, such as insulin, to a patient. The infusion set or patch pump has a bottom surface pH indicator capable of producing a color change upon contact with the pharmaceutical agent. The pH indicator in one embodiment is bromothymol blue that is able to exhibit a color change when contacting an insulin solution to produce a rapid visually detectable color change.
