The C-tron is a powerful control box that can support a combination of up to four different sensors, measuring dissolved oxygen, suspended solids, pH and ORP simultaneously. C-tron is easy to navigate with an intuitive interface and robust software. The plug & play capabilities of C-tron ensure easy installation and sensor management. Calibration is performed in just a few simple steps. The control box comes standard with Modbus RTU and Modbus TCP/IP outputs. It can also feature expansion slots for extra input/ outputs. The smart built diagnostic software is ensuring the functionality of each sensor with interactive feedback. The Relay outputs in the C-tron are used for high and low alarms or to provide a pulse for automatic cleaning.

The C-tron is compatible with Cerlic C-tron series sensors.
