The explorer is used by the dentist to detect decay.
An electroscope is the instrument used to detect static charge. It consists of a metal-leaf or needle that responds to the presence of electric charge by diverging from its equilibrium position.

The periodontal instrument used to detect calculus is the explorer, specifically the periodontal explorer. This instrument features a thin, pointed tip that allows dental professionals to carefully probe the tooth surfaces and detect the presence of calculus, plaque, and other irregularities. The tactile sensitivity of the explorer helps in identifying hard deposits that may not be visible to the naked eye.
A tsunami detection buoy is one of the primary instruments used to detect tsunamis. These buoys are equipped with sensors that can detect changes in water pressure caused by a tsunami wave passing overhead. The data collected by these buoys is then transmitted to monitoring stations to provide early warnings.

A sound level meter is typically used to detect noise. It measures the intensity (loudness) of sound in decibels (dB) to quantify noise levels in different environments.
An electrocardiogram (ECG or EKG) is the instrument used to detect electrical currents from the heart. This test records the electrical activity of the heart over a period of time, typically a few minutes, to assess its health and function.
measuring instrument in which the echo of a pulse of microwave radiation is used to detect and locate distant objects
A tonometer is the medical term for the instrument used to measure the pressure in the eye to detect glaucoma. The tonometer shoots a blast of air into the eye, directly into the pupil.A tonometer is used to measure eye pressure.
An ammeter is commonly used to detect electron flow in a circuit. The ammeter measures the amount of current (flow of electrons) passing through a specific point in the circuit.
