Pressure Meter: This meter measures the pressure of either air or liquid vapor. You must attach the pressure meter to a red hotspot on the container (see Container (Evaporation)).

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

In the pressure meter's Properties Box, you can set it to measure air or liquid vapor pressure.

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