The Model 15-3032 Direct-Reading Humidity-Temperature Reader is a
transistorized electronic meter for measuring relative humidity and temperature of
paper in any location where normal ac power is not available, or is not readily
accessible. It has all components and self-contained power supply necessary for
making temperature and humidity measurements when connected by a cable to a sensor
in the probe.
b. The probe used with the humidity-temperature reader is a portable inspection
tool for measuring the moisture condition of stacked paper. The blade of the probe
houses a sensitive hydroscopic humidity sensor. The electrical resistance of the
sensor changes with the changes in moisture content of the air surrounding it.
These changes are measurable electronically with the aid of the portable humidity-
temperature reader.
