CDTX-111
Industrial process conductivity/temperature controllers
CDTX-111 and CDTX-112 are panel instruments for
in-process monitoring of conductivity. Range switch
over and cell constant checks can both be freely
set and adjusted during operation. Unique signal
collection and processing technology, and a special
thick film circuit are employed to ensure accurate
measurements and stable operation. Other features
include linearized data, automatic temperature
compensation, and maintenance-free cells. The
control functions trigger relays based on conductivity
setpoints. The CDTX-111 and CDTX-112 are ideal
auxiliary instruments for many types of water testing
applications.
