4-20mA online digital pH ORP controller for water

In the treatment of wastewater, the role of pH ORP analyzer is very important. The purpose of wastewater treatment is to remove or degrade pollutants in wastewater to meet environmental discharge standards or reusable water quality requirements. It is necessary to choose a controller with high precision, good stability, and real-time monitoring. So what is the role of the Digital PH ORP Controller in the wastewater treatment process? First of all, the wastewater from some production processes is highly acidic or alkaline, and needs to be neutralized to adjust the pH value. The pH ORP Controller can monitor the pH value of the wastewater, and adjust the pH range of the solution by controlling the dosing through the relay to ensure that the wastewater meets the neutralization requirements. ORP treatment also uses a similar method to adjust the dosage of oxidants or reductants to degrade organic matter or remove certain pollutants. Secondly, as a digital and automatic pH ORP controller, it has 4-20mA current output and RS485 output, which can be integrated with other instruments and control equipment to realize the optimization and automation of wastewater treatment process.

Features

1. pH ORP controller with 4-20mA current output, can output pH value or ORP value and temperature
2. A two-wire RS485 interface, supports standard Modbus protocol, convenient for networking
2. Two configurable relays, which can set the closing value and breaking value, control the dosing pump
3. IP66 protection level, dustproof and waterproof when used outdoors
4. Wide voltage DC or AC optional to prevent interference caused by voltage instability
