اخبار شرکت From Wastewater to Aquaculture: APX1-C1/C1Z pH/ORP Controller Applications Across Industries

One Controller, Many Industries

The APX1-C1/C1Z Online pH/ORP Controller is designed for the continuous monitoring of pH or ORP in aqueous solutions, which makes it an exceptionally versatile instrument. Because water quality is critical in so many sectors, the same rugged controller can be found performing reliably in an impressive range of applications worldwide.

Typical Application Areas

• Municipal and industrial wastewater treatment: monitor pH through neutralisation and precipitation stages, and use ORP to control disinfection and dechlorination processes.
• Chemical and pharmaceutical processing: maintain precise pH setpoints for reactions, crystallisation, and effluent neutralisation, protecting both product quality and downstream equipment.
• Water supply and drinking water plants: verify pH stability and ORP levels to ensure safe, compliant potable water.
• Aquaculture and fish farming: keep pH and redox conditions within the narrow bands required for healthy aquatic life.
• Cooling towers and boiler systems: track pH and corrosion-related ORP to extend equipment life and reduce maintenance costs.
• Food and beverage production: control pH in washing, CIP (clean-in-place), and process water to meet strict hygiene standards.
• Metal finishing and electroplating: monitor ORP for chrome reduction and cyanide destruction in waste treatment lines.
• Swimming pools and spas: maintain balanced pH and effective ORP for reliable disinfection.

Flexible Control for Real Processes

In each of these environments, the APX1-C1/C1Z proves its value through flexible control. Its two SPST relay outputs can be assigned to main value control, temperature control, or a timed wash cycle, while high-alarm and low-alarm logic configures automatically depending on the relationship between the on-value and off-value setpoints. A dedicated wash relay can drive automatic sensor cleaning, and a hold function freezes the displayed reading during cleaning to avoid false alarms.

Outputs That Integrate

For data logging and SCADA integration, the controller provides one active current output configurable as 4~20 mA or 0~20 mA with a maximum load of 1000 Ω, plus optional RS485 MODBUS-RTU communication. Operators can therefore bring pH, ORP, and temperature values directly into their central control systems.

Whatever the industry, the APX1-C1/C1Z delivers consistent, accurate, and actionable water quality data that keeps processes efficient and compliant.

Why One Instrument Fits So Many Roles

The controller's versatility comes from a combination of wide measurement ranges, selectable probe types, and configurable control logic. Because it accepts both pH glass and antimony probes, as well as standard ORP probes, the same hardware can be commissioned for very different chemistries. The temperature input supports NTC10K and PT1000 sensors, and the two relay channels can be repurposed between main-value, temperature, and wash duties according to the process. This adaptability means a single spare part can serve an entire site, simplifying inventory and maintenance planning.

Supporting Compliance and Sustainability

Regulators increasingly require facilities to demonstrate continuous, documented control of water quality. By providing reliable pH, ORP, and temperature data, with analog and digital outputs for logging, the APX1-C1/C1Z helps operators build the audit trail that compliance demands, while also supporting the sustainability goals of reduced chemical consumption and lower waste volumes.
