MODEL SOLU COMP II
SECTION 1.0
DESCRIPTION AND SPECIFICATIONS
Measures conductivity in the range 0 to 20,000
µ
S/cm.
Display choices are conductivity, resistivity, and TDS
(total dissolved solids). Three temperature corrections
are available: high purity water (dilute sodium chlo-
ride), cation conductivity (dilute hydrochloric acid),
and adjustable linear temperature coefficient (0 to
5.00%/°C). Temperature correction can be disabled,
allowing the analyzer to display raw conductivity.

RECOMMENDED SENSORS FOR CON-
DUCTIVITY:
The Solu Comp II is intended for use with the
ENDURANCE Model 400 series conductivity sensor
(Pt 1000 RTD).
Model 400 Screw-in/Insertion
Model 400VP Screw-in/Insertion with 6.0 VP connector
Model 401 Screw-in/Insertion (except 401-15)
Model 402 Retractable

The analyzer can also be used with Rosemount
Analytical conductivity sensor Models 140, 141, 142, and
150 having a Pt 100 RTD.
Refer to the table to select the appropriate cell constant.
Ratio Conductivity (Codes -20-30):
The Dual Conductivity Solu Comp II can function as a
ratio analyzer or recovery device (% passage or %
rejection). Product sensor 2’s conductivity reading is
always displayed.
