1 ABOUT YOUR GAUGE
The Elcometer 319 Dewmeter gauge is used to
check climatic conditions in the surface treatment
industry.
Your Elcometer 319 measures:
• Air temperature
• Relative humidity
• Surface temperature
From these measured values, your gauge then
calculates:
• Dewpoint temperature
• Delta T (∆T)
The Elcometer 319 Dewmeter has readings
memory and an internal clock. This allows
measurements and a date/time stamp to be
stored as they are taken.
The stored data can be viewed on the display,
printed via an infra-red link or downloaded to a
PC using an optional interface cable.

1.1 Climatic conditions
The risk of condensation
forming on surfaces about to
be coated is always present
and is difficult to assess
without suitable instruments.
In particular, it is difficult to
detect condensation on blast
cleaned surfaces.
Surfaces with a temperature
at or below this dewpoint
temperature will be covered
with condensation/moisture.
It is important to take
measurements at regular
intervals and at different
points on the surface.
Factors like sun, shadow,
shape and mass of the
object to be coated can
create unexpected thermal
behaviour on the surface.
The memory in your Elcometer 319 will record
climatic conditions during a coating job.
1.2 Standards
Your Elcometer 319 Dewmeter can be used in
accordance with the following National and
International standards:
BS 7079-B4 ISO 8502-4
NACE RP propo 97
