Emissivity; Reminders - Amprobe IR-710 Manual De Uso

Emissivity

Emissivity describes the energy-emitting characteristics
of materials. Most organic materials and painted or
oxidized surfaces have an emissivity of about 0.95. If
possible, to compensate for inaccurate readings that
may result from measuring shiny metal surfaces, cover
the surface to be measured with masking tape or flat
black paint (<150°C / 302°F ) and use the high emissivity
setting. Allow time for the tape or paint to reach the
same temperatures as the surface beneath it. Measure
the temperature of the tape or painted surface.

Reminders

1. Changes of surrounding ambient temperature
can result in inaccurate reading, allow time for
the instrument to adopt the change of ambient
before use. Specified accuracy applies after 30
minutes when the instrument changes to a different
environment ambient.
