The CDCN670/680 has been discontinued. Please see the PHUCN600 as a possible substitute or contact our pH and Environmental department.

CDCN680 series conductivity analyzers are designed for use with CDE680 conductivity sensors in applications of pure water up to 200 mS. The two sensor inputs can be independently configured to measure conductivity, resistivity, total dissolved solids or to make a two-sensor calculation such as % rejection, % passage, difference or ratio. CDCN670 series analyzers are designed for use with CDE3600 series electrodeless conductivity sensors for applications from 200 µS to 2000 mS, particularly where coating and polarization can cause problems with other types of electrodes. The sensor input can be configured to measure conductivity, % concentration or total dissolved solids. Both the CDCN670 and CDCN680 series are available in either 1 /4 or 1 /2 DIN versions. All models have either two or four relay outputs and two analog outputs. The 1 /2 DIN models feature a large LCD display and hardware for wall, pipe or panel mounting.
