1 Description and specifications
1.1 General
Rosemount 225 toroidal conductivity sensors are intended to be used in many
pharmaceutical and food and beverage applications where a sanitary design is required.
These corrosion and fouling resistant sensors are ideal for measuring the concentration of
CIP solutions, detecting product/water interfaces, checking product quality, and
monitoring eleuents in chromatographic separations.
1.2 Unpacking and inspection
Complete the following steps when you unpack your instrument.
Procedure
1. Inspect the shipping container. If there is damage, contact the shipper immediately
for instructions.
2. If there is no apparent damage, unpack the container and remove the sensor.
3. Ensure that all items shown on the packing list are present. If items are missing, If
items are missing, contact your local Customer Care representative
4. Save the shipping container and packaging.
They can be used to return the sensor to the factory in case of damage.
