➢Directly to a computer
➢Into a network hub that communicates with a remote facility monitoring
system
• RS-232 Port: The RS-232 port is used for calibration, sensor control, or
TouchRAM communications.
Each kind of connection requires its own cabling configuration.
• Sample Outlet: Sampled air is discharged from the sample outlet after passing
through a HEPA filter.
NOTE:
Ensure that the sample outlet is not blocked. If it becomes
blocked, maintaining a standard airflow will become difficult. If the
airflow varies too much, the readings may not be valid.
