Introduction
The DewCheck4 dewpoint gauge is specially
developed to check climatic conditions in the
surface treatment industry according to ISO
8502-4, ASTM D3276-05, BS 7079-B4 and
NACE RP prop 97.
There is always a risk of condensation on
surfaces to be treated. Condensation is difficult
to spot without suitable instruments, in
particular on blasted surfaces.
The phenomenon of condensation also
depends on three highly changeable climatic
factors. The ambient temperature, the surface
temperature, and the dewpoint (calculated with the relative
humidity) should be measured at
regular intervals.
It is not only important to take frequent measurements; they
should also be taken at different areas of the surface. Factors
such as the sun-shadow side and the shape and the mass of
the object to be painted can create unexpected thermal
behaviour of the surface.
In order to document the climatic conditions during a coating
job, the DewCheck4 is equipped with two types of internal
memory. The memory for manual logging can store up to
6,000 records in a maximum of 8 batches. The memory for
interval logging can store up to 12,000 records in a maximum
of 8 batches.
Data can be evaluated on screen or exported to a PC using
the optional DewCheck4 Dock. This optional extension can
also be used to measure the surface temperature with an
external sensor.
