ConductivityMeasuringCells

forHigh-TemperatureApplicationsConduMaxWCLS12

Two-electrodemeasuringsensorswithcellconstantk=0.01/cmork=0.1/cm

TechnicalInformationTI082C/24/ae

Areasofapplication

TheconductivitymeasuringcellCLS12isdesignedforindustrialandpowerplantapplications（e.g.condensatemeasure-mentwherelowconductivitiesmustbemeasuredunderhighpressuresandtemperatures.

Themeasuringrangeofthecellsdependsonthecellconstantk.

•k=0.01/cm:

0.04to20µS/cm•k=0.1/cm:

0.1to200µS/cm

MeasuringcellswithaPt100temperaturesensorareusedtogetherwithconductivitymeasuringinstrumentsequippedwithautomatictemperaturecompensation:

•MycomSCLM153

•LiquisysMCLM223/253•MyProCLM431
