Probe: Borosilicate or quartz glass tubing with a heating system capable
of maintaining a probe gas temperature during sampling of
120 ± 14 °C (248 ± 25 °F)
Gas Temperature Sensor: A temperature sensor capable of measuring temperature to within ±3 °C
(5.4 °F). The sensing tip of the temperature sensor is in direct contact with
the sample gas, and
monitored during sampling.
Filter Box Temperature
Sensor: A temperature sensor capable of measuring to within ±3 °C (5.4 °F). The
temperature around the filter holder is regulated and monitored during sampling.
Glass fiber filter, without organic binder, exhibiting at least 99.95
percent efficiency (<0.05 percent penetration) on 0.3 micron dioctyl phthalate
smoke particles. Labeled and tare weighed.
Vacuum Line: Connects the
filter holder to the
Sensor: Placed at the outlet of the last impinger. Used for monitoring the exit
temperature - 20 °C (68 °F) or below.
Capable of maintaining a temperature around the filter holder during sampling
