EXTECH AN500 Hot Wire Thermo Anemometer

The Extech AN500’ s 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 of the Extech AN500 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 ( 8 mm) fits easily in 3/ 8" holes Telescoping probe extends to 7 ft ( 2.1 m) 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 Specifications: m/ s range: 0..2 to 20m/ s m/ s max resolution: 0.01m/ s m/ s basic accuracy: ± 3% ft/ min range: 40 to 3940ft/ min ft/ min max resolution: 1ft/ min ft/ min basic accuracy: ± 3% MPH range: 0.5 to 45MPH MPH max resolution: 0.1MPH MPH basic accuracy: ± 3% Knots range: 0.4 to 40knots Knots max resolution: 0.1knots Knots basic accuracy: ± 3% km/ h range: 0.7 to 75km/ h km/ h max resolution: 0.1km/ h km/ h basic accuracy: ± 3% CFM/ CM Range: 0 to 999, 999 CFM/ CMM CFM/ CMM max resolution: 0.01 Temparature range: 32 to 140° F ( 0 to 60° C) Temparature max resolution: 0.1° Temparature basic accuracy: ± 2° F ( ± 1° C) Dimensions/ weight: 7.1 x 2.8 x 1.3" ( 180 x 72 x 32mm) / 12.5oz ( 355g)
