TCon probe

Conductivity probe, digital

The TCon conductivity probe is based on the conductive measurement method with two graphite electrodes and temperature-dependent measurement compensation.

Digital communication ensures safe and trouble-free transmission of the signal from the sensor to the controller. The sensor incorporates an automatic compensation of the measurements according to the temperature.

The state of the sensor is indicated by an operation LED in the upper part of the sensor, allowing visual identification of the correct functioning of the pH meter.

Available with a fixed cable of 2 or 10 meters and M12 connector. Possible cable extensions of 0.3 m, 2 m, 10 m and 25 m.

Measurement principle

The digital TCon probe works with TriBox Mini and TriBox transmitters.
Once the probe is connected, the transmitter powers the sensor, receives and uses the data. The measurements are displayed on the screen, they are recorded and can be converted to the 4-20 mA analog signal.
Interface on web browser accessible by Wifi or Ethernet.
