Inductive conductivity meter

8228 • Configurable outputs: up to 2 transistor
and up to 2 analogue 4... 20 mA outputs
• Removable backlighted display
• Simulation of process values and
diagnostic functions
• Sensor-versions available with PEEK,
PVDF or PP

Please see fitting S020

The analysis gauge, Type 8228, includes a detachable display module. This Envelope Dimensions [mm] (see datasheet for details)
is used for setup, configuration and calibration or required as a process
70 70
value display. For temperature calibration, a temperature sensor is included 97 97 65 65
as standard.
