You think probable to a frequency meter.
Frequency counter
An oscilloscope is commonly used to measure frequency by displaying the waveform of the signal and showing the number of cycles per second. Other instruments like frequency counters or spectrum analyzers can also be used to measure frequency accurately.
An oscilloscope or a frequency counter can be used to measure frequency. Oscilloscopes display the waveform of a signal and can measure its frequency, while frequency counters directly count the number of signal cycles per second to determine frequency.
A frequency meter is the instrument that is used to measure the amplitude of sound. It reads the energy from a sound wave.
it is an instrument which is used to measure relative amplitudes of single frequency components of complex waveform.
The term used for the measure of frequency is "Hertz (Hz)".
No. The instrument used to measure wind speed is an anemometer.
The instrument which is used to measure snowfall is called a snow gauge.
A thermometer
There is no single instrument for either of these things
