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.
The instrument that can measure the density of an earthquake is called an seismometer. The first seismoscope dates back to 132 AD.
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 very common instrument for the direct measurement of the density of a liquid is the hydrometer, which measures the volume displaced by an object of known mass. A common laboratory device for measuring fluid density is apycnometer; a related device for measuring the absolute density of a solid is a gas pycnometer. Another instrument used to determine the density of a liquidor a gas is the digital density meter - based on the oscillating U-tube principle.
A seismograph records the intensity measured by the Ritcher Scale.

A force-meter measures the force of an object pulled along a surface.
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.

an alimeter is a weather instrument which measures the alitude of an object above a fixed level
