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.

R
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

3 GETTING STARTED
3.1 Fitting batteries
Alkaline batteries must be disposed of carefully to
avoid environmental contamination. Please
consult your local Environmental Authority for
information on disposal in your region.
Do not dispose of any battery in fire.
The condition of the batteries is indicated by a
symbol on the display - see “What the symbols
mean” on page 8.
To retain time and date, fit new batteries within 30
seconds of removal of the exhausted batteries.
Always check the time and date after battery
replacement. Data in the memory is not affected
by removal of the batteries.
3.2 Switching the gauge on and off
To switch the gauge on, press .
To switch the gauge off, press . The guage
can be set to switch off automatically 2 minutes
after the last key press - see “Gauge set up” on

4 THE SENSORS
The sensors for
humidity, air
temperature and
surface temperature
are located in the
probe at the top of
the gauge.
For accurate readings:
• Do not obstruct airflow through the slots in the
probe around the humidity and temperature
sensors.
• Keep your fingers away from the slots - the
heat from your body may affect readings.
• Allow the gauge some time to acclimatise
once it is brought from a cold environment
into a warm place or vice versa.
To avoid damage:
When measuring surface temperature, do not
use excessive force when pressing the probe
against the surface. This will not improve the
speed of measurement nor the accuracy but may
lead to wear or damage of the sensor-tip.
5 ∆T ALARM
∆T is calculated by subtracting the dewpoint
temperature from the surface temperature. When
this value is less than 3°C the gauge will start to
beep, the ‘Alarm’ icon will be displayed and the
backlight will flash on and off.

6 TAKING A READING
1. Hold the gauge with the probe in the area to
be measured.
If you are measuring surface temperature,
hold the gauge with the tip of the probe in
contact with the surface to be measured.
For good contact, hold the gauge
perpendicular to the surface.
2. Use the arrow buttons and to
select the parameter required (ambient,
surface, dewpoint or ∆T).
Relative humidity and the selected
temperature will be shown on the display.
3. Press to freeze the current readings on
the display (display shows HOLD)
For instructions on storing readings in gauge
memory see the next section.
7 USING YOUR GAUGE MEMORY
The memory in your Elcometer 319 Dewmeter
can store up to 99 datasets. Each dataset
comprises of one set of measurements:
• relative humidity
• ambient temperature
• surface temperature
• dewpoint temperature
•∆T (delta T)
• time and date
Data in the memory can be viewed on the screen
of your gauge, printed via an infra red link, or
exported to a PC using an optional interface
cable.
Datasets can be deleted if required.
