Final answer:
A large recirculating air handling system would impact the results from scientific measurement devices.
Step-by-step explanation:
A large recirculating air handling system would dramatically impact the results from scientific measurement devices, assuming all placement protocols are followed. These devices are used to measure various parameters such as temperature, humidity, air quality, and air velocity. When the air in the system is recirculated, it can affect the accuracy and reliability of these measurements due to changes in airflow patterns and contamination of the air being measured.
