เครื่องวัดความเร็วลม Model CEM DT-619

Digital CFM CMM Thermometer Anemometer Vane Wind Velocity Air Flow Meter NEW!!
From USA

This is a brand new CEM DT-619 certified digital Thermo- Anemometer. This 2-in-1 meter measures the air flow / air velocity and the air temperature simultaneously. DT-619 has fast response, high accuracy design for the most demaning jobs.

This device is a must have for measuring the wind speed (up to 108 Kmeters per hour) and air flow (up to 999.9 cubic meters per minute). The built-in thermometer measures the air temperature (up to 60 deg C) as the air speed is measured. DT-619 was designed to be used at home, office, factory or industrial building.

This device operates on a 9V battery and is very portable due to its light weight.
