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
