Glossary

A printed issue of this reference booklet was published in 1996 (in English and German) to celebrate the 50th birthday of the SIGRIST process photometers. To optimize display of the formulas and expressions, you will need the True-Type character set Symbol, which should be installed on your system. If it isn't installed, select this link for download.
