There are many types density, like true density, tap density, bulk density etc. Can use analyzer like G-DenPyc 2900 gas pycnometer analyzer to measure them.
Aerometer or Hydrometer for density of liquids, Dasymeter for density of gases and Resonant Frequency and Damping Analyser (RFDA) for density of solids.

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.
DENSITY : density is the ratio of mass and volume of the substance density=mass/volume RELATIVE DENSITY : It is the ratio of density of a substance to the density of water
The frequency of a string depends on its length, linear density, and tension. Most musical instruments are designed to make it easy to quickly change the tension; this will tune the instrument, or rather, the corresponding string.
relative density is related to the density of water. i.e. a relative density of 19.3 means that it has a density 19.3 times the density of water. The density of water is 1g/ml therefore the density of gold is 19.3g/ml
Using different types of instruments for the measurmentof density: densimeters, pycnometers, electronic vibrational densimetres, etc.

Errors in measurement are the most likely cause, either due to limitations in the instruments used, or error in reading the measurements.
A ruler.

Percussion instruments are instruments that can be tuned or not but tuned instruments are tuned.
A major application of a micropycnometer is that it allows one to measure the density of a solution when one only has a small volume available. For example, I would like to know the density of an H2018 sample. This stuff costs several hundred dollars per mL. My desitometer requires a minimum of 1.2mL. If I had a micropycnomter, I could get away with only needing a fraction of that amount
The collective noun for instruments is a set of instruments.

The instrument used to measure the density of a liquid is a hydrometer. These are often made for specific purposes, because the density of a given liquid may not vary much. Milk hydrometers are used to estimate the creaminess of raw milk. A battery hydrometer is used on your car battery, for the density of the sulphuric acid varies with the amount of lead dissolved, which indicates the state to which the battery is charged.
Davis Instruments is a company that offers several technical weather instruments. These kinds of instruments are used to test the weather and atmosphere.
Of course they had instruments, but you don't specify what sorts of instruments you mean. Do you mean musical instruments?
