Extech 407119 Particle Counter

The Extech 407119 is engineered to provide accurate and reliable measurements in various HVAC and ventilation applications. Its telescoping probe, extending up to 3 feet, allows for easy access to ducts and hard-to-reach areas, making it suitable for both residential and industrial environments. The device measures air velocity from 40 to 3,346 ft/min and airflow in both CFM (ft³/min) and CMM (m³/min), providing comprehensive data for airflow analysis. Simultaneously, it measures air temperature, offering a holistic view of environmental conditions.

The 407119 features a large 1.4″ LCD display that shows air velocity, airflow, and temperature readings clearly. Users can choose to display airflow as an instantaneous value or as a 20-point average, depending on the specific requirements of the task. Additional features include data hold, Min/Max recording, and auto power-off, enhancing usability and energy efficiency.

For data management, the device includes an RS-232 interface, allowing users to connect it to a PC for data logging and analysis. This feature is particularly useful for professionals who need to document and review measurements over time. The 407119 operates on four AA batteries, ensuring portability and convenience for field measurements.
