universal
controllers
The GDH-UC1 and GDH-UC2 Universal Controllers provide a powerful and flexible platform for monitoring and controlling water quality processes.
Designed for seamless integration with the full range of GDH digital and analog sensors, these advanced controllers support measurements including pH, ORP, conductivity, dissolved oxygen, turbidity, sludge concentration, residual chlorine, ammonia, nitrate, COD, and more. This includes full compatibility with the GDH-PHSD-801 Digital pH Sensor, delivering highly accurate, real-time pH monitoring with plug-and-play simplicity.
The GDH-UC1 offers a single-channel architecture with hybrid analog and digital sensor support, while the GDH-UC2 extends capability with dual-channel operation, allowing one or two sensors to be connected simultaneously for greater flexibility and future expansion.ph monitoring with gdh sensor compatibility
The GDH-UM1 is an economical and highly versatile digital analyzer monitor designed for reliable water quality measurement and process monitoring. Built to work with the full range of GDH digital sensors, the GDH-UM1 provides a simple, cost-effective solution for pH measurement while also supporting conductivity, dissolved oxygen, turbidity and other water quality parameters. When paired with the GDH-PHSD-801 Digital pH Sensor, the GDH-UM1 delivers accurate, dependable pH monitoring for treatment plants, industrial processes and environmental applications.
Its compact design, straightforward installation, and standard communications make it an ideal choice for customers seeking performance without the complexity and cost of a full universal controller.
