  • Page 43: Measurements An Black Bodies (cavity Radiators)

    Operating instructions • Small objects with medium and high temperatures can also be easily and accurately measured. • When measuring materials with low specific heat, a non-contact method does not induce heat loss which would distort the temperature reading (as is the case with contact temperature probes).
  • Page 44: Measurements Errors

    Operating instructions furnace - which applies to all other self-contained targets - always show a reading which is too low. Considerable errors can occur at targets with reflecting, polished or bright surfaces, e.g. molten steel and metal without oxide layer and ceramic materials.
  • Page 45 Operating instructions Using a reference emissivity coefficient Apply matte black colour to a part of the surface to be measured. This part has an emissivity of 94 %. At first, measure the temperature of the coloured part. Then make a comparative measurement right next to the coloured part and adjust the emissivity on the pyrometer until it displays the previous measurement reading again.
  • Page 46: Maintenance

    Operating instructions 18 Maintenance 18.1 Cleaning the pyrometer lens A false temperature reading will be given when the lens is dirty. Therefore, check the lens periodically and clean it, if necessary. Dust can be removed by simply blowing it away or by using a soft brush. A special lens cleaning cloth is ideal, but any soft, clean, lint-free cloth will be suitable.
