Figure 3.57 Mean Cage Temperatures vs. Supply Discharge Temperature 
Figures 3.58 and 3.59 show the cage and room NH 3 concentrations on day 4 plotted against 
supply relative humidity (RH). The cage values show no notable trend with quite a wide 
variation at the standard supply RH of 61 percent. However, even though there is some scatter in 
the data, the room NH 3 concentration plot shows a clear trend to higher values at higher supply 
RH.
