Choosing a Saccharimeter

Rudolph makes it easy to match a saccharimeter to your budget and application. The Autopol IZ and IIZ were designed for limited budget applications where 0.02°Z (ISS) accuracy are sufficient. For the more demanding accuracy applications, Rudolph offers the Autopol 589, 880 and 880T models that have ±0.01°Z (ISS) accuracy, OD 4.0 dark sample penetration power and feature rich software.
