To measure the amount of sulfur dioxide (SO2) coming out of a volcano, you would use a correlation spectrometer. This instrument is specifically designed to detect and quantify gas emissions, including sulfur dioxide, by analyzing the absorption of specific wavelengths of light by the gas. Other instruments listed, such as a seismograph or tiltmeter, are used for monitoring seismic activity and ground deformation, respectively, but not for gas measurement.
