| Temperature Meter: This meter measures the temperature of either air, liquid vapor, or the liquid itself. To measure air or vapor temperature, you must attach the temperature meter to a red hotspot on the container (see Container (Evaporation)). To measure liquid temperature, you must attach a temperature meter to the blue hotspot. 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 temperature meter's Properties Box, you can set it to measure temperature in either Kelvin (default) or Celsius. You can also set it to measure air, liquid vapor, or liquid temperature. You must place a temperature meter to plot temperature using the graph tool.
