Measuring
of material moisture
with data logger and user programmable
material curves
GMH 3850
resistive material-moisture meas. device
with data logger
This instrument is indispensable for the documentation of material state
by quality assurance systems. By means of the integrated
data logger there
can be recorded up to 10.000 measuring values and processed on demand.
Additionally there can be 4 material curves individually programmed by the
user to data acquired
by reference measurings with dry ovens or CM-method.
This instruments finally makes the usage of paper correction tables and so
on obsolete.
