The Mod. 125 pH sensor consists of a body in PP or PVDF which houses the glass electrode for measuring the pH, the reference electrode with salt bridge, the temperature sensor, the earth contact of the solution and the electronic signal management card. This card is a self-powered electronic circuit capable of providing a ± 500mV output (0 ÷ 1 V on request), which allows the sensor to be connected to a normal pH meter. For the PT100 temperature sensor, the output from the sensor is in ohms.

The Mod.225 ORP electrodes are designed for Redox potential measurements in particularly demanding applications where standard electrodes would not be able to work because the reference life would be too short. The ORP sensor Mod.225 consists of a body in PP or PVDF which houses the measuring electrode, the reference electrode with salt bridge, the temperature sensor, the ground contact of the solution and the electronic management board of the signal.
