A.1 Module
Monitor UPC-900 is an on-line monitor for measurement of UV-
absorption, pH (optional in ÄKTA
FPLC) and conductivity. The
monitor can work with standard glass pH electrodes with a built in
liquid-filled reference electrode and a BNC connector.
Conductivity measurement has a dynamic range from 1 µS to 999.9
mS/cm and is suitable for a wide range of applications.
