c. A digital thermometer is recommended although a metal stem is an

possible breakage that could result in contamination of the entire system developer (see
figure 7-3).
Figure 7-3. Digital thermometer with metal stem.
d. A secure 3-month supply (100 in a box) of control film that was produced with

e. You will need the recording forms and charts.
