What is a ducter tester?

A duct tester is a specialized device used to measure the airtightness of ductwork in heating, ventilation, and air conditioning (HVAC) systems. It helps identify leaks and inefficiencies in duct systems by pressurizing or depressurizing the ducts and measuring the airflow and pressure drop. This information is crucial for ensuring optimal system performance, energy efficiency, and indoor air quality. Duct testers are commonly used during building inspections and energy audits.
