What measures density
It measures air pressure.
The answer depends on what the "b" measures are and how they differ from the "a" measures and also "c" and other subsequent measures.
Thermometer measures temperature. Barometer measures atmospheric pressure. pH meter measures acidity or alkalinity. Spectrophotometer measures the amount of light absorbed or emitted by a substance. Geiger counter measures radiation levels. Hygrometer measures humidity. Anemometer measures wind speed. Voltmeter measures electric potential difference. Spectrometer measures the wavelengths of light emitted by a source. Mass spectrometer measures the mass-to-charge ratio of ions.
a barometer measures air pressure. an anemometer measures wind speed. a thermometer measures temperature.
A snow gauge measures snow.
IT MEASURES THE INTELLIGENCE OF HUMAN ONLY.
A phsychrometer measures relative humidity
