Extech 407119 Heavy Duty Hot Wire Anemometer

The Extech 407119 Heavy Duty CFM Hot Wire Thermo-Anemometer is an advanced instrument designed to accurately measure air flow, air velocity, and temperature. Ideal for HVAC professionals and industrial technicians, this device offers precise readings across multiple airflow conditions, enhancing diagnostics and system performance.

Its telescoping probe extends up to 3 ft (940 mm), making it perfect for inspecting air ducts and other tight spaces. It delivers fast, reliable measurements of air flow in both CFM (cubic feet per minute) and CMM (cubic meters per minute), with options for instantaneous or averaged readings over 20 points.

This anemometer can detect air velocities as low as 40 ft/min, enabling detailed airflow analysis in low-flow environments. The large 1.4" LCD display ensures easy readability of results, and the simultaneous temperature measurement in °F/°C provides comprehensive data for climate assessments.

What's Included:

• 1 - Telescoping Probe With 5.5Ft Cable
• 4 - AA Batteries
