FQ90xxx Heat Flow PLates Type

Technical Features:
● For determining the heat flow density up to max. 150°C.
● Application-oriented designs, consisting of a meander of opposing thermocouples that are embedded in a substrate.
● In case of thick substrates no lateral circulation of the heat flow because of sufficient meander shell zone.
● Software for k value measurement, see page 06.07.

▒ Each heat flow plate has been assigned a calibration
value, which corresponds to the heat flow density in
W/m2 when the plate provides an output of 1mV. The
calibration value will be stored as factory-setting in the
ALMEMO® connector so that ALMEMO® devices will
immediately indicate the current heat flow density in
W/m2.
