Silly question, but why would such a device send an encrypted signal in the first place? If the range is so short, isn't that sufficient security? It would be similar to blocking the view so that nobody reads your screen, because it may contain sensitive data. I doubt pH is that sensitive to anyone.

Edit: A bit of Googling suggests there's some pretty bad setups in the wireless medical device market. Like pacemakers where you can send commands TO the pacemaker, with no authentication, signing or encryption[1]. Oof.
