KERN balances and other instru ments, which
allows retrieving and controlling all relevant
parameters and functions of the device. KERN
devices featuring KCP are thus easily integrated
with computers, industrial controllers and other
digital systems

GLP/ISO log:

The balance displays serial number, user ID,
weight, date and time, regardless of a printer
connection

GLP/ISO log:

With weight, date and time. Only with KERN
