Information about the device
Device description
The pyrometer TP7 uses an infrared sensor to measure surface
temperatures without contact. An integrated multi-laser pointer
serves for the determination of the measuring spot.
You can set the emission ratio of the material to be measured so
as to achieve a more precise measurement result.
For the temperature measurement the device allows you to set
freely definable thresholds. Exceeding or falling below these
preselected thresholds is indicated by an acoustic alarm
function and visually by a changed display colour.
The display can be illuminated as needed. When not in use, an
automatic switch-off saves the battery.
Measuring principle
The device measures the temperature by means of an infrared
sensor. Important factors playing a role in the temperature
measurement are the measuring spot diameter and the degree
of emission.
Measuring spot
Observe the ratio of the distance(D) to the measuring spot
diameter(S). The larger the distance to the object, the larger the
measuring spot diameter and hence, the less precise the
measured result. The device calculates an average temperature
from all the temperatures in the measuring spot.

Degree of emission
The degree of emission is used to describe the energy radiation
characteristics of a material.
Most organic materials have an emissivity of0.95. Metals or
shiny materials come with a much lower value.
A material's emissivity depends on various factors, e.g. on
• Material composition
• Surface condition
• Temperature
The emissivity can range between 0.1 and 1 (in theory).
The following rule of thumb can be assumed:
• When a material is rather dark and its surface texture matt,
it probably has a high emissivity.
• The brighter and smoother the surface of a material, the
lower will be its emissivity, presumably.
• The higher the degree of emission of the surface to be
measured, the better it is suited for non-contact
temperature measurement by use of a pyrometer or
thermal imaging camera, since falsifying temperature
reflections become negligible.
Nevertheless, entering a degree of emission as appropriate as
possible is indispensable for a precise measurement.

Carrying out a measurement
Info
Please note that moving from a cold area to a warm
area can lead to condensation forming on the device's
circuit board. This physical and unavoidable effect can
falsify the measurement. In this case, the display
shows either no measured values or they are incorrect.
Wait a few minutes until the device has become
adjusted to the changed conditions before carrying out
a measurement.
• Ensure that the surface to be measured is free of dust, dirt
or similar substances.
• To be able to gain exact measurement results on surfaces
which reflect heavily, stick matt masking tape to the
surface or apply matt black paint with a very high and
known degree of emission.
• Note the 40:1 ratio of the distance to the measuring spot
diameter. For accurate measurements the measuring
object should be at least twice as large as the measuring
spot.
