Heidelberg Medical manufactures the Heidelberg pH Capsule System, a radiotelemetric capsule that measures intragastric pH in real time. First described in 1964, it has been in continuous clinical and research use ever since.

The Heidelberg capsule began as a published method for measuring gastric function, not as a product. It was refined into a manufactured instrument over the decades that followed, and it has stayed in clinical and research use the entire time, a rare span for any diagnostic device.
