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.

Emissivity table

The table below may be used as reference for setting the degree of emission. It supplies reference values for the emissivity of common materials.

Operation

Inserting the battery

Note
Make sure that the surface of the device is dry and the device is switched off.

1. Open the battery compartment by folding open the cover (22) with your fingers.
2. Use the battery clip (21) to connect the new battery  (1 x 9 V) with correct polarity.
3. Close the cover of the battery compartment.

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.

Carrying out a quick measurement
