KDM-110 on-line PH meter with 4-20mA and RS485 output for wastewater treatment
Introduction
The KDM-110 On-line PH Meter is a game-changer in the realm of wastewater treatment. Engineered with cutting-edge technology, it offers precise pH measurement capabilities crucial for maintaining the delicate balance of wastewater treatment processes. What sets it apart is its dual output options: the 4-20mA current output and RS485 interface. The 4-20mA output allows seamless integration with a wide range of control systems, providing real-time pH data in a format easily understood by automated machinery. This means that chemical dosing can be adjusted instantaneously based on the pH readings, optimizing treatment efficiency. Meanwhile, the RS485 output enables multi-drop connections, facilitating communication with multiple devices and centralized data collection. In large-scale wastewater treatment plants, operators can monitor and manage pH levels across different zones, ensuring compliance with environmental regulations. Its robust design and reliable performance make the KDM-110 an indispensable asset in safeguarding our water resources and the environment.
