Heated Compartment

As shown in Figure 5.11.1, the probe is connected to the heated compartment that contains the filter holder and other particulate-collecting devices, such as the cyclone and flask. The filter holder is made of borosilicate glass, with a frit filter support and a silicone rubber gasket. The compartment is insulated and equipped with a heating system capable of maintaining the temperature around the filter holder during sampling at 248 ± 25°F (120 ± 14°C), or at another temperature as specified by the EPA. The thermometer should measure temperature to within 5.4°F (3°C). The compartment should have a circulating fan to minimize thermal gradients.
