1. lntroduction
TM-40X series measures air speed, temperature
and humidity. lt is ideal for spot measurements
at air outlets on account of its 30mm vane. ln
addition
to air speed and temperature,
TM-404
also
measures
air moisture and absolute
pressure.
ln this way, air conditions can be reliably checked.
