you would use a scale to measure the mass and a beaker to measure the volume.
i need another tool
You do the Mass of the object then, divide the Volume away from it.
The answer will depend on what characteristic of the object is being measured: its mass, volume, surface area, colour, density etc.
Length measures the distance between two points, volume measures the amount of space an object occupies, mass measures the amount of matter in an object, weight measures the force of gravity acting on an object, density measures how compact the matter in an object is, and temperature measures the degree of hotness or coldness of an object.
volume
Density = Mass / Volume. There is not an instrument that will measure both so you will need to measure them separately and calculate the density.
A seismometer is the instrument that measures the density of an earthquake, which is done by detecting and recording the vibrations produced by seismic waves. These measurements help scientists determine the magnitude and intensity of an earthquake.
A seismograph records the intensity measured by the Ritcher Scale.
Any instruments that can measure mass and length. (not at the same time, doesnt have to be the same instrument). By measuring the length, height and width of an object you can determine it's volume and by weighing it you can determine it's mass. From these results it's possible to calculate the objects density.

an alimeter is a weather instrument which measures the alitude of an object above a fixed level
A Westphal (or Mohr) balance.A flotation raft or object of science, non raft. ETC.)
A hydrometer is an instrument that measures the density of liquids. Auto batteries could be checked to see the strength of the acid in each cell before sealed batteries were made. I don't know of an instrument for solids or gases.
