Loop or mains power
The CT700 is an on-line conductivity analyser available as a 4-wire mains powered unit or a 2-wire loop-powered unit. The loop-powered unit requires a supply voltage between 16 and 35V and re-transmits the conductivity value by varying the loop current between 4 and 20mA. The mains powered unit runs on either 110 or 230V (specify the required voltage when ordering) and re-transmits the conductivity value on a separate 24V loop.
Intuitive User Interface
Four-button programming provides intuitive navigation through the menu driven user interface.
Dual Alarm Relays/Analog Outputs
AC operated systems provide two relays that are configurable as control or alarm.
Diagnostic messages provide a clear description of system condition, which eliminates confusing error codes that can be difficult to decipher.
Two-point and sample calibration options include stability monitors to check temperature and main parameter stability before accepting data.
