TM-402 ~ 404 Air Velocity Meter

TM-402 ~ 404 Air Velocity Meter

This Velocity meter is 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, also measures air moisture and absolute pressure. In this way, air conditions can be reliably checked.
