Extech's AN300 series of 10cm (4in) large vane thermo-anemometers allows for more precise readings on larger size ducts. Each meter simultaneously displays airflow or air velocity and temperature. Applications include HVAC, manufacturing, engineering, appliance testing, research and design, and more. The AN300 measures air velocity and air flow, air temperature, and perfoms multipoint and timed average calculations with Min./Max. and data hold. We also supply the AN320 (57-6101) which adds relative humidity, wet bulb, dew point and carbon dioxide (CO2) measurement. The AN300 is supplied with 4 x AAA batteries and a hard case. * Built-in thermistor for air temperature * Uses 4 x AAA batteries with auto power-off * Dimensions 269 x 106 x 51mm (10.6 x 4.2 x 2in) * Weighs 200g (7oz) https://elecena.pl/product/27754372/extech-an300-anemometer 2025-01-24 https://elecena.pl/product/27754372/extech-an300-anemometer 2025-03-25 https://elecena.pl/product/27754372/extech-an300-anemometer 2025-05-24 https://elecena.pl/product/27754372/extech-an300-anemometer 2025-07-21 https://elecena.pl/product/27754372/extech-an300-anemometer 2025-09-20 https://elecena.pl/product/27754372/extech-an300-anemometer 2026-02-25 https://elecena.pl/product/27754372/extech-an300-anemometer 2026-04-13
