| FEATURES |
|
BENEFITS |
 |
| Ultra-Pure
Compensation |
|
Ultra-pure
water temperature compensation insures accuracy at conductivities of less
than 1 NS/cm. |
|
|
|
| Wide
Measurement Range |
|
Wide
range of measurement covers applications from ultra-pure water to liquids
with conductivity up to 10,OOONS/cm. |
|
|
|
| Universal
Scaling |
|
Incorporates
universal scaling to provide the best resolution for your application requirement.
Measurement range can be scaled to NS/cm, pS/m, mS/cm, mS/m, Mohm-cm, TDS
and ppm. |
|
|
|
| m On-Line
Diagnostics |
|
Comprehensive
diagnostics continuously verify analyzer operation of the entire sensing
loop with built-in software protection. |

NOTE:
To select the most suitable cell constant for the desired range use the
following criteria:
Minimum range 10 x the cell constant
Maximum range 10,000 x the cell constant
e.g. cell constant k=0.1 Minimum range = 10
x 0.1 = LOONS/cm
Maximum
range = 10,000 x 0.1 = 1000NS/cm
For ultra-pure water
applications (less than LOONS/cm) a cell constant of 0.05 must be used. |
