Tenmars TM-404 Air Velocity Meter
TM-404 Velocity, Flow, Temperature, Humidity, Pressure Meter.
TM-404 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.
