Reflectometer Head
Glass area
The glass area on the face must not be soiled, scratched or damaged.
1. Check whether there are any soot deposits or filter paper fibres each time
you change the filter paper.
2. Clean the reflectometer head carefully with a puffer and a soft brush, with
ultra-pure pressurized air, or replace it.
Jacket surface
• Check the blackening of the visible jacket surface of the inside reflectometer
head housing between the glass area and the end of the reflectometer
head. It must be even (no scratches…).
Measuring head
The polymeric material of the measuring head must be clear, transparent and
colourless - no colouring is allowed.
• Replace the measuring head, if the polymeric material is coloured yellowish
or brownish.
We recommend replacing the reflectometer head every 2 years:
