The controller, which is based on a high-performance CPU, incorporates a evident digital display, an isolated 4 to 20 mA signal output, and high/low limit relay alarm functions. With these features, operators can monitor changes in water quality and comply with predetermined dimension limits, making the instrument work as part of an industrial monitoring and control system.
product key technologies
The PH-110 online industrial PH controller is an intelligent upgrade product of industrial acidity controller, which can continuously measure and control the PH value of sewage. This device is suitable for urban sewage treatment plants, chemical industry, printing and dyeing, papermaking, pharmaceuticals, electroplating and environmental protection and other fields.
According to the environment and characteristics of water industry, combined with international power supply standards, considering the electrical design specifications for special environments, 220V AC and safe low-voltage 24V AC and 24V DC power supply options are added.
Measurement signals can be sent to a suitable PLC, data acquisition module, or process monitoring system using the isolated 4- to 20 mA output. For physical alarm circuits or manage equipment, the high and low limit relay alarm functions provide extra switching signals.
The PH-110 is suitable for fixed online checking points where constant acidity measurement and transmission integration are required because of its industrial-oriented design and magnetic compatibility features.
Common uses include ecological monitoring, textile dyeing, electroplating, chemical processing, pharmaceutical production, and municipal wastewater treatment.

Application
When constant pH assessment and physical sign transmission are required, the PH-110 Online Industrial pH Controller can be integrated into business water monitoring systems. Process guidance is supported by its dimension, analog output, and alarm functions for a range of water treatment applications.
1. Wastewater Treatment for Textile Dyeing and Printing
During manufacturing and treatment, the pH levels of textile dyeing wastewater may change and change. Operators can monitor procedure changes while performing neutralization and wastewater treatment using virtual pH monitoring.
A common monitoring setup includes a PH-110 controller connected to a pH electrode that is installed in a suitable sampling location or treatment tank. High and low restriction alarms help determine pH levels outside the predetermined range, while the secluded 4- to 20 mA output can convey the measurement signal to a central control system.
2. Water therapy and purification systems
To evaluate the performance of water treatment systems and its value, pH measurement may be required at specific process stages.
At a suitable tracking location, the PH-110 can provide online pH measurements and digital signal comments. The water's characteristics, permeability, flow conditions, and required measurement performance should be taken into account when choosing and installing an electrode.
A suitable electrode and picking agreement should be considered before choosing a measurement system for applications involving high-purity or ultrapure water.
3. Monitoring of the waste from electroplating
Neutralization, precipitation, and other substance treatment steps may be involved in soldering wastewater treatment. Operators can check the state of the treatment process by monitoring pH at related process points.
A appropriate external monitoring system can be connected to the PH-110 to receive pH measurement signals. When configured assessment thresholds are reached, switching signals can be provided using its high and low reduce relay alarm functions.
4. Wastewater Treatment at Municipal and Industrial
acidity tracking is important for equalization, neutralization, and other treatment stages in wastewater treatment plants. For process control, the PH-110 may be connected to appropriate external control equipment.
5. Procedure water for pharmaceuticals and purposes
At various stages of waters preparation and treatment, acid levels may need to be monitored in chemical and pharmaceutical facilities. The controller can be used to reduce alarm signals for plant operators by limiting the range of measurement points for pH readings, analog transmission, and other appropriate measurements.
Application settings support
According to the actual operation conditions, electrode types, mounting holder, cable length, and control system connection should be chosen. When requesting a task quote, please include the water characteristics, location, measurement, and control requirements.
