Soot number comparison scale

Soot number comparison scale for easy determination of the soot number during flue gas measurements.

This soot number comparison scale is a reliable aid for clear and confident assessments of oil-fired systems. It enables you to evaluate soot loading quickly and easily by comparing the darkening on the filter paper with the graded fields on the scale, as defined for manual soot number measurement. The scale is held next to the measured soot spot so that the soot number can be read off directly. Its clear layout and good legibility make differences immediately visible, helping you to assess combustion quality at a glance. The robust design is suitable for daily use.
