PH Controller MIK-DC-P2 Dual Channel Universal Controller

The MIK-DC-P2 is an intelligent online multi-parameter controller with up to two measuring channels. It can measure pH, ORP, conductivity, dissolved oxygen, turbidity, sludge concentration, residual chlorine, ammonia nitrogen, nitrate nitrogen, COD and more, transmit data to a DCS or computer, and control cleaning systems or pumps.

The first channel works in hybrid mode and accepts either an analog sensor or a digital sensor. The second channel connects a digital sensor. You can start with one sensor and add a second one later, which avoids buying a second controller.

The MDC-P1/P2 series supports up to two channels, and the P2 is the dual-channel version. Please tell us how many sensors you need to connect so we can confirm the right model.

• pH: 0.00–14.00 pH; ORP: -2000 to 2000 mV
• Dissolved oxygen: 0–40 mg/L; saturation 0–200%
• Conductivity: 0–500 mS/cm; inductive conductivity: 0–2000 mS/cm
• Turbidity: 0–4000 NTU; sludge concentration: 0–120,000 mg/L
• Residual chlorine: 0–100 mg/L
• Ammonia nitrogen: 0–1000 mg/L; nitrate nitrogen: 0–1000 mg/L
• COD: 0–1500 mg/L

Actual measuring ranges depend on the technical data of the connected sensor.

• Measured variables: pH, ORP and antimony electrodes
• Range: pH/antimony -2.00 to 16.00 pH; ORP -2000 to 2000 mV
• Accuracy: pH ±0.02 pH; antimony ±0.2 pH; ORP ±2 mV
• Resolution: 0.01 pH; 1 mV
• Repeatability: 0.02 pH
• Input impedance: ≥10¹² Ω

An antimony electrode is a metal pH electrode without a glass membrane. It is generally used in applications where glass electrodes are unsuitable, such as media that attack glass or where breakage is a concern, although its accuracy is lower than a glass electrode (±0.2 pH on this controller).

• NTC10K: ±0.3 °C from -10 to 60 °C; ±2 °C from 60 to 130 °C
• Pt1000: ±0.3 °C
• Pt100: ±0.3 °C
• Temperature range: -10 to 130 °C

Manual compensation is supported, as well as automatic compensation with linear, acid, base (alkali) and pure water modes, so the controller can adapt to different solutions.

Yes. The controller automatically recognizes Asmik digital sensors for plug-and-play convenience, so one controller can replace several specialized controllers.

Two isolated 0/4–20 mA outputs, each configurable to a measurement range, with a load capacity of 750 Ω and output accuracy of ±0.1% FS. The outputs comply with NAMUR NE 43, which defines standard current signal levels for failure indication.

It has an optoelectronically isolated RS485 interface with Modbus-RTU protocol for connection to a DCS, PLC or computer for remote monitoring and logging.

• 3 SPST relays: 2 alarms + 1 cleaning
• NO/NC type, capacity 250 VAC, 5 A
• Adjustable relay delay: 0–9999 seconds
• High and low alarms with adjustable hysteresis amount and time

Yes. The dedicated cleaning relay can control a sensor cleaning system, and the alarm relays can switch pumps at set points. The current outputs can also be used for proportional control through a PLC. See our metering pumps for dosing.

Yes. An optional NB-IoT wireless communication module and mobile app allow real-time data viewing on mobile devices.

It has a 4.3-inch full-view color screen with quick switching between digital display and real-time curve modes. It can store up to 500,000 data records.

The controller supports Chinese, English, Spanish and Korean.

• AC: 85–265 V, 50/60 Hz
• DC: 21.6–26.4 V

Power consumption is ≤28 W.

The controller has IP66 protection and a UL94 V-0 flame-retardant housing, making it suitable for demanding working conditions. Cables enter through M20×1.5 cable glands.

• Spring terminals: AWG16–AWG24 (0.2–1.5 mm²) cables
• Plug-in terminals: AWG12–AWG28 cables

Rack-mounted (panel) and wall-mounted installation methods are available.

• Operating temperature: 0 to 60 °C; relative humidity 10% to 85% (non-condensing)
• Storage temperature: -15 to 65 °C; relative humidity 5% to 95% (non-condensing)
• Altitude: below 2000 m

• pH electrode health self-diagnostic alert after maintenance
• Current simulation function for loop testing
• Separate power ground and signal ground design for better anti-interference
