1.0 GENERAL INFORMATION

1.1 Introduction

1.1.1 This manual provides information on AquaMetrix Model MS Series flow-through and
submersion sensors. Conductivity sensors have long been called cells. The two
terms, cell and sensor, are used interchangeably in this manual.

1.2 Cautions To Be Observed

1.2.1 Consult the factory before using sensor in extremely strong solvents such as
ethylene dichloride. Also, do not exceed the sensor’s maximum ratings listed in
Section 2 of this manual.

1.2.2 Before placing sensor into service, remove protective plastic cap.

1.2.3 Do not exceed the maximum sensor-to-analyzer distance specified for the analyzer
you are using.

1.2.4 Be sure the cell constant is appropriate for the scaling of the analyzer. The constant
is given in the numerical part of the model number. For example, MS001P has a
constant of 0.01; MS1P has a constant of 1.
