Why not? It works as an alarm, is simple in design and requires no external input.
They need to be checked 3x per day anyway for temperature so someone will notice eventually. And checking temperature must be product core temp so no remote monitoring. Unless haccp changed massively over the last 20 years to "we don't care anymore".
