INTRODUCTION
The LaMotte Multi-Range Conductivity Meter is a portable, battery-operated
instrument with solid state circuitry. The meter accurately measures a wide
range of conductivity with a single probe. A conductivity reading measures the
capacity of a solution to conduct an electric current and is directly related to
the total ionic concentration of dissolved substances in the solution.
The instrument’s extensive capabilities range from checking the purity of
distilled water to use as a salinometer for monitoring the conductivity of sea
water. Other applications include checking air and water pollution, evaluating
electroplating baths, measuring soluble salts in soils, and monitoring industrial
and municipal water treatment operations.
This easy-to-use instrument has a rugged 3a” taut-band meter movement with
a mirrored scale that eliminates reading errors due to parallax. Other features
include a battery check circuit and manual temperature compensation from 0°C
to 100°C.
The conductivity meter is equipped with a range selector which monitors
conductivities from 0-10,000 micromhos/cm in four different ranges: 0-10;
0-100; 0-1000; and 0-10,000 micromhos/cm. A single conductivity probe on a
twelve foot cable is used to measure all four ranges. An optional
interchangeable probe is available with fifty feet of cable for measuring
conductivity profiles in deep water.
Should it be necessary to return the instrument for repair or servicing, pack the
instrument carefully in suitable container with adequate packing material. A
return authorization number must be obtained from LaMotte Company by
calling 1-800-344-3100. Attach a letter with the authorization number to the
shipping carton which describes the reason for the return. This valuable
information will enable the service department to make the required repairs
more efficiently.
