A barometer measures atmospheric pressure.
A voltmeter measures the difference in voltage between two points
A wavelength has nothing to do with either of these measurements.
A barometer measures atmospheric pressure, which can indicate changes in weather patterns. A voltmeter measures electrical voltage and would not typically be used to measure environmental changes. To measure environmental changes, instruments such as thermometers, hygrometers, anemometers, or spectrophotometers would be more appropriate.

An electrodynamometer can work as a voltmeter by judging the wavelength and force of the electricity, much the same at the voltmeter, then converting it to a force that is more recognizable.
A thermometer and light meter are the most useful when measuring two environmental changes.
A barometer measures the barometric pressure of the atmosphere. Units of millibars. That is one-thousanth of a bar. 0.001 bar equals a millibar.A voltmeter measures electricities potential to do work measured in volts A.C. and D.C.. Most can also measure resistance in ohms and current in amps. Some can measure frequency (hertz= cycles per second) and capacitance in farads.CommentIn SI, barometric pressure is measured in pascals (Pa).
It is a voltmeter which can only measure direct current.
A voltmeter measures voltage in volts.
The device used to measure air pressure is called a barometer. It can be either an aneroid barometer or a mercury barometer, both of which are commonly used to measure atmospheric pressure.
