nnnn

temperature probe Pt 100

nnnn

The measuring instrument automatically displays the

nnnn

measurement parameters temperature, relative humidity,

nnnn

dewpoint, pressure dewpoint, absolute humidity, degree of

nnnn

humidity and enthalpy, and additionally presents the current

nnnn

values, the last measured values, min., max. and mean

nnnn

values at the press of a button.

nnnn

Measurement data can be stored by measurement site in
