An acid dosing channel should be connected to the last channel of the dosing
module.
Depending on the pH, different material is used for an acid dosing channel.

Connecting EC sensor
One or two EC sensors can be connected to the FertiMiX Pro C. If two sensors are
connected, the first sensor in the direction of water flow is the control sensor, and the
second sensor is the verification sensor (also see section "Measurement module
(sensors)" on page 14).
To connect an extra or new EC sensor, complete the following steps:
1. Make sure that there is no water pressure in the FertiMiX.
2. Connect the wiring according to the included wiring diagram.
3. Calibrate the sensor. See section "Calibrating the sensors" on page 45 for
explanation and documentation.
4. Unscrew the sealing cap at the location where the sensor will be connected.
5. Place the sensor in the hole.
You can find more information in the "EC Sensor Insert" provided.
An extra EC sensor must also be added to the configuration (see "Software
configuration" on page 38).

Connecting pH sensor
Zero, one or two pH sensors can be connected to the FertiMiX Pro C. If two sensors
are connected, the first sensor in the direction of water flow is the control sensor, and
the second sensor is the verification sensor (also see section "Measurement module
(sensors)" on page 14).
To connect an extra or new pH sensor, complete the following steps:
1. Make sure that there is no water pressure in the FertiMiX.
2. Connect the wiring according to the included wiring diagram.
3. Remove the protective cap from the sensor.
4. Calibrate the sensor. See section "Calibrating the sensors" on page 45 for
explanation and documentation.
5. Unscrew the sealing cap at the location where the sensor will be connected.
6. Place the sensor in the hole.
You can find more information in the OEM manual provided with the pH sensor.
An extra pH sensor must also be added to the configuration (see "Software
configuration" on page 38).
