6.4.1 Example emissivities chart
The emissivity describes the energy emission behaviour of materials. Most (90 % of typical
applications) organic materials and painted or oxidised surfaces have an emissivity of 0.95
(default setting in the meter).
If you measure shiny or polished metallic surfaces, this will result in a loss of accuracy. If possible,
cover the surface to be measured with temperature-resistant black tape or a thin layer of black
paint. Wait a little while until the tape or paint layer has reached the same temperature as the
material underneath. Now measure the temperature on the tape or painted surface.

11 Disposal
For the disposal of batteries in the EU, the 2006/66/EC directive of the European Parliament
applies. Due to the contained pollutants, batteries must not be disposed of as household waste.
They must be given to collection points designed for that purpose.
In order to comply with the EU directive 2012/19/EU we take our devices back. We either re-use
them or give them to a recycling company which disposes of the devices in line with law.
For countries outside the EU, batteries and devices should be disposed of in accordance with
your local waste regulations.
If you have any questions, please contact PCE Instruments.
