2. Tutorial

The Hygropin is a multifunction hand-held indicator with data logging capability that can be used
for identifying, diagnosing and monitoring potential moisture problems. Each of the two probe
inputs can be configured independently. The integrated real time clock keeps track of date and
time while recording data.
Practical advice for measuring humidity
The most common source of error when measuring relative humidity is a difference between the
temperature of the probe and the temperature of the environment. At a humidity condition of 50
% RH, a temperature difference of 1°C (1.8 °F) typically results in an error of 3 %RH on relative
humidity.
When using Hygropin, it is good practice to monitor the display for temperature stability. The probe
should be given sufficient time to come to equilibrium with the environment to be measured. The
larger the initial temperature difference between the probe and the environment, the more time is
required for temperature equilibrium.
In extreme situations, condensation may occur on the sensors when the probe is colder than the
environment. As long as the humidity / temperature limits of the humidity sensor are not exceeded,
condensation does not alter the calibration of the sensor. However, the sensor has to dry out be-
fore it can provide a valid measurement.
