PH Controller SUP-MDC-P2 Dual Channel Universal Controller
00334-HW-SUPMEA-034
Overview
The MDC-P1/P2 is an advanced, intelligent online multi-parameter controllercapable of supporting up to two channels. The first channel's hybrid mode allows for the connection of either analog or digital sensors, while the second channel connects digital sensors.

This controller can measure a variety of parameters including pH, ORP, conductivity, dissolved oxygen, turbidity, sludge concentration, residual chlorine, ammonia nitrogen, nitrate nitrogen, COD, and more. Its continuous monitoring data can be transmitted to a DCS system via output transmission or communicated with a computer using the Modbus-RTU protocol via RS485 interface for remote monitoring and logging. It can also control cleaning systems or pumps.
