With its dual-channel capability, hybrid input mode, and extensive data logging features, the MDC-pH offers unparalleled flexibility and accuracy for optimizing your process control and ensuring product quality. 

Key Features:

• Hybrid input: Supports both analog and digital pH/ORP sensors, providing flexibility in sensor selection and maintenance.
• Dual-channel measurement: Measures and controls two independent channels of pH or ORP, allowing for simultaneous monitoring of multiple parameters.
• High-precision measurement: Offers accurate and reliable readings with a wide measurement range and high input impedance.
• Temperature compensation: Provides automatic or manual temperature compensation with various compensation modes and temperature sensor options.
• Advanced alarm functions: Three SPST relays (two alarms + one cleaning) with adjustable hysteresis and delay settings provide comprehensive alarm capabilities.
• RS485 communication: Isolated Modbus-RTU RS485 communication enables seamless integration with SCADA systems and data logging.
• Dual (0/4-20) mA outputs: Two isolated and configurable analog outputs allow for flexible connection to other process control instruments.
• Large color display: 4.3-inch full-view color display with quick toggle between digital and real-time curve modes provides clear visualization of data.
• Extensive data logging: Stores up to 500,000 data records, enabling comprehensive historical data analysis and trend monitoring.
• IP66 protection: Rugged design with IP66 ingress protection ensures reliable operation in harsh industrial environments.
• Wireless communication: Optional NB-IoT wireless communication allows for remote monitoring and data access via a mobile app - please enquire.
