Description
The MC125 PH & Redox Controller is a combo, PH & REDOX controller meter. It has two coupling sockets to connect external equipment (ozone generator, electro-valve or dosing pump) The MC125 PH and Redox Controller coupled with a solenoid valve for CO2 and an ozone generator is ideal for aquariums, fish farming. 1/ In its PH function, the MC125 PH and Redox Controller continuously measures the PH and we can attach a solenoid valve or any solenoid valve or dosing pump that will be activated when the controller meter has passed the chosen set point. In its PH function, the MC125 PH and Redox Controller has a scale of 0.0 up to 14.4 pH. Its calibration is manual. Its external equipment control block has a wheel to set the setpoint: from 4 to 8 pH. At the same time as the outdoor equipment is activated, a visual alarm (red LED) will also be activated. The calibration of the MC125 PH and Redox Controller in its PH function is manual (at 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) 2/ In its Redox function, the MC125 PH and Redox Controller continuously measures the redox potential of your water. Redox is a method of controlling water quality; It tells us about the oxidation/reduction potential of water. a) Aquariums: In fresh water, from 250mV are considered good values. Seawater values range from 350 to 400mV. b) Swimming pools: The value necessary to eliminate certain bacteria is 600mV. c) Wastewater: Redox measurement is mainly used in the detoxification of wastewater, with the reduction of chromate or oxidation of cyanide. The MC125 PH and Redox Controller has another socket and coupling (in addition to the PH function coupling socket), to connect an ozone generator that will be activated when the controller meter has passed the setpoint we have chosen. In its ORP Redox function, the MC125 is factory calibrated. 3/ Installing the MC125 PH & Redox Controller : Connect the 12VDC adapter of the MC125 PH & Redox Controller meter to a multi-socket power strip Connect the 12VDC transformer to the power supply and the MC125 monitor Connect the coupling sockets to the power supply (2 x Black and white socket) Connect the ORP Redox MA921 probe to the monitor on its ORP connector Connect the MA911 PH probe to the monitor on its PH connector Remove the plugs electrode protectors. Immerse the pH and Redox electrodes in the water to be measured (2.5 cm) and let them float with the help of a wide polyexpan, for example. Turn on the meter by pressing the ON/OFF button Choose PH or Redox menu by moving the central black button (Top: ORP Redox; Down : PH) In both functions, choose the direction of the parameter (e.g. for PH rising, button in “above” position); The same in the Redox menu. Set the set point for each parameter, with the help of the graduated wheel for each parameter. Allow the reading to stabilize and the meter will begin continuous monitoring. A visual alarm indicates when the measurement exceeds the set point. When the alarm is activated, the docking station is also activated, and from there the auxiliary equipment is turned on. PH Calibration : Go to the PH menu (central black button down) Immerse the electrode in a sachet of pH7.01 calibration liquid and wait for the data to stabilize. With the help of the screwdriver, set the data to pH7.0 Immerse the electrode in a sachet of pH4.01 or pH10.01 calibration liquid and wait for the data to stabilize. With the help of the screwdriver, set the data to pH4.0 or pH10.01 The meter is calibrated and ready to measure in PH. It is advisable to calibrate the meter at least once a month, or after a long period of non-use or after electrode change. Good measurements with the MC125 PH Controller and Redox.
