Turn on humidification solenoid if 75 percent calorimeter has a lower humidity and turn 
on dehumidification pump if it has higher humidity. 
Check fresh airflow going into drierite with the bubble flow meter. 
Put old drierite into oven and bake (see detailed procedures). 
8:40 Turn off the dehumidifier and record the humidity values of each calorimeter. 
10:30 Calibrate the PhD meter with NH 3 by using a standard ammonia gas (52.7 ppm) and the 
fresh air. 
Calibrate CO 2 and O 2 analyzer by using two standard gases (CO 2 0.55 percent, O 2 17.5 
percent and CO 2 1.58 percent, O 2 18.9 percent). 
Record the atmospheric pressure from mercurial barometer (Fortin Type, model 469). 
10:40 Record the CO 2 , O 2 , RH (see other detailed procedures), temperature, and airflow. 
Measure NH 3 of each calorimeter and room using PhD meter and calorimetric tube, 
respectively. 
1 1:20 Start the second sample period, in which NH 3 is measured only using PhD. 
p.m. 
12:00 Start the third sample period, which is same as second one. 
12:30 Turn off the white light. Start the dehumidification system in the 35 percent calorimeter. 
1:30 Turn off the dehumidification system. 
3:00 Calibrate the PhD meter with standard NH 3 gas (52.7 ppm) and fresh air. 
Calibrate CO 2 and O 2 analyzer. 
Record the atmospheric pressure. 
3:15 Record the CO 2 , O 2 , RH, temperature, and airflow for all three calorimeters. 
Measure NH3 using PhD meter and calorimetric tube. 
4:00 Start the second sample period of the afternoon, in which NH 3 is measured only with PhD 
meter.
