1 Description and specifications
1.1 Description
The Rosemount 222 toroidal flow through conductivity sensor measures conductivity in
highly conductive liquids up to 2 S/cm (2,000,000 μS/cm). A noninvasive flow through
design allows for in-line installations without any obstruction to sample and makes these
sensors ideal for use with viscous or fibrous liquids.
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. Save the box.
3. If there is no apparent damage, unpack the container. If there is no apparent
damage, unpack the container and remove the sensor.
4. 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
5. Save the shipping container and packaging.
