What instrument do we use to measure the electrical and mechanical vibrations
seismograph
A galvanometer is an instrument that is used to measure current or voltage. It can have a mechanical movement, ie a needle that moves round a scale, or it can be digital as many are now.
An electrical ammeter.
Frequency counter
a pressure transmitter is a devise to measure the mechanical pressure and convert in to electrical signal it may be 4~20mA or 0~10V
The wattmeter is an instrument to measure the electrical power.
An Ammeter is used to measure electrical current, which is measured in Amperes (or Amps).
Either an ammeter or a galvanometer is.
Hydrometer
A conductometer (conductivity meter) is an instrument designed to measure the electrical conductivity.
A cardiograph is an instrument designed to measure and record the electrical activity of the heart.
