CONDUCTIVITY CONTROLLER CC-421

Zoom

CC-421 is a stationary device used for continuous conductivity and temperature measurements in clear water or sewage. The device is available in three versions
- equipped with two relays;
- equipped with 0 ÷ 20 mA or 4 ÷ 20 mA, current loop;
- equipped with RS-232 output to connect with a computer.
Optionally, the connection may be made by USB output with use of RS to USB converter (additional equipment).
The device enables 1-point calibration of the measuring cell by entering the constant K value or in standard solution with value set in the device's memory.
It is possible to calibrate it without the need of disconnecting the outputs.

Characteristic features:

• Meter is equipped with a backlit LCD display.
• 4 sub-ranges switched automatically.
• Possibility to choose between two versions of the device: conductivity or salinity measurement version (converted to the NaCl – up to 150 g/l).
• Converting conductivity into salinity based on the actual characteristics, not on a constant coefficient.
• Automatic temperature compensation.
• Constant temperature α coefficient 2 %/°C.
• Reference temperature: 25 °C.
• 24 months of warranty, quick warranty and after-warranty service.
