Density Meter: This meter measures the density of small, medium, or large-particle gases. You must attach the density meter to a red hotspot on the container (see Container (Diffusion)).

Only the probe connects to the hotspot on the container. The meter itself appears above or below, along with the particle size of the gas it is probing. You can move the meter, but you cannot delete it. To delete the meter, you must delete the probe.

In the density meter's Properties Box, you can set it to measure small, medium or large particle gas densities.

You must place a density meter to plot density using the graph tool.
