TM-403/4 Air Velocity Meter

TM-401/TM-402/TM-403/TM-404

TM-40X series measures air speed, temperature and humidity. It is ideal for spot measurements at air outlets on account of its 30mm vane. In addition to air speed and temperature.

TM-404 also measures air moisture and absolute pressure. In this way, air conditions can be reliably checked.
