diagnostic devices

Fault-finding instruments

Diagnostic devices are tools or instruments used to identify problems, conditions, or malfunctions.

In medicine, they include blood pressure monitors, MRI machines, and home pregnancy tests.

In automotive and computing contexts, diagnostic devices detect mechanical failures or system errors: The mechanic hooked up a diagnostic device to read the engine codes.

The phrase emphasizes the investigative function—gathering information to determine what's wrong.
