Above Cabinet Sampling
The sampling pipe is installed directly over the cabinets to be protected. Sampling holes are placed over the
cabinet ventilation grille. The holes are drilled so that they face into the air stream from the cabinet. Each
monitored cabinet must have at least one sampling hole. The exhaust fan can cause sampling problems due
to the high airflow around the sample pipe.
