The MC122 PH controller is a continuous PH meter with alarm and electrical outlet to activate external electrical equipment.

This equipment that can be coupled to the MC122 PH controller can be, for example, a dosing pump that will be activated when the controller meter has passed the set point and that will inject PH corrective solution into the tank; Also the equipment to attach to the MC122 PH controller can be an electro valve (solenoid valve) to inject CO2 into your aquarium.

MC122 PH controller with solenoid valve is ideal for your aquarium, fish farming; And with a pH corrector dosing pump, the MC122 is ideal for correcting the pH of your nutrient tank for your traditional crop or hydroponic crop.

The MC122 PH controller has a scale from 0.0 to 14.4 pH. Its calibration is manual. Its external equipment control block has a dial to set the set point: from 0.5 to 9.5 pH. At the same time that the outdoor equipment is activated, a visual alarm (red LED) will also be activated. Calibration of the MC122 PH controller is manual (in 2 points: pH 7.01 and pH 4.01/10.1)

Range: 0.0 to 14.0 pH

Resolution: 0.1pH

Accuracy: 0.2pH

pH electrode: MA911B/2, with 2 meter cable, BNC connector (included)

12 VDC adapter (included)

MC122 PH Controller Installation and Measurement

Connect the 12VDC transformer to the power

Connect the Docking Base to the power supply (white and black socket)

Connect the PH electrode to the base of the meter

Remove the probe protection before any measurement.

Make sure the meter was calibrated before use.

Immerse the pH electrode (2.5 cm) in the liquid in the tank (let it float with the help of a wide polystyrene for example).

Turn on the meter by pressing the ON/OFF button Choose the PH control mode (for PH > set point: press “above” / For pH < set point: press “below”)

Allow the reading to stabilize and the meter will begin continuous monitoring. A visual alarm indicates the moment the measurement exceeds the set point. When the alarm is activated, the docking base is also activated, and from there the auxiliary equipment is turned on.

The set point can be selected by adjusting the center front knob to the desired value.

The selection scale goes from 5.5 to 9.5pH

Calibration: Remove the electrode protection.

Immerse the electrode in a sachet of pH7.01 calibration liquid and wait for the data to stabilize. With the help of a screwdriver, adjust the data to pH7.0

Set the PH4/PH10 button to the PH4.0 data.

The meter is calibrated and ready to measure.

It is advisable to calibrate the meter at least once a month, or after a long period of non-use or after changing the electrode.
