USP and EP

The limit functions for pharmaceutical water in accordance with USP and EP specifications are

implemented in the software for conductivity measurements:

• "Water for Injection" (WFI) as per USP <645> and EP

• "Highly Purified Water" (HPW) as per EP

• "Purified Water" (PW) as per EP

The uncompensated conductivity value and the temperature are measured for the USP/EP limit

functions. The measured values are compared against the tables defined in the standards. An alarm

is triggered if the limit value is exceeded. Furthermore, it is also possible to configure an early

warning alarm that signals undesired operating states before they occur.

ChemocleanPlus

Freely programmable sequence control

• e.g. for automatic sensor cleaning in retractable assemblies for reliable measurement results in

processes with a high risk of contamination

• Individual, time-based activation of 4 outputs e.g. relays

• Starting, stopping or pausing of activities via digital input or fieldbus signals e.g. from limit

position switches

Maintainability

Modular design

The modular transmitter design means it can be easily adapted to suit your needs:

• Retrofit extension modules for new or extended range of functions, e.g. current outputs, relays and

digital communication

• Upgrade to maximum 2 photometers and 4 Memosens inputs

• Optional: M12 sensor connector for connecting any kind of Memosens sensor

• Optional: CDI connector for external access to the service interface (avoids having to unscrew the

housing cover)
