Description

AN500 Hot Wire CFM/CMM Thermo-Anemometer by Extech

New sensor technology delivers major improvements in durability and ATC (Automatic Temperature Compensation) for accurate in-duct Air Velocity measurements with changing air temperatures. Telescoping probe with ruler label ensures that measurements are made in the center of the duct even if out of reach. Ergonomic directional handle and anti-rotation sensor confirms that probe direction and airflow direction are aligned for confident readings.

Features

Reads Air Velocity and Temperature on dual display
Calculates CMM / CFM based on adjustable duct shape and size
Slim sensor (8mm) fits easily in 3/8" holes
Telescoping probe extends to 7ft (2.1m)
Sensor cover for Zero Adjustment and storage protection
Adjustable parameters for Altitude and GAIN
Save and view 36 readings on display
Min / Max / Average and Data hold
Auto Power off with disable
