pH/ORP Combo Sensors: Dual-Measurement Accuracy for Water Quality Systems
Monitoring pH and ORP simultaneously is vital in wastewater and aquaculture. A pH/ORP combo sensor merges both electrodes into one body, cutting installation points and maintenance.

Why Opt for a Combination Probe?
Using separate pH and ORP sensors doubles the hardware, cable runs, and potential failure points. A single combo probe simplifies tank or pipe integration, saves space, and ensures synchronized readings—ideal for chemical dosing, cooling towers, and neutralization processes.
Certifications That Open Global Doors
When exporting instrumentation, certifications validate safety and quality. Our sensors carry CE marking (EU conformity), ISO 9001 (manufacturing excellence), and RoHS (hazardous substance compliance). These credentials help distributors meet international regulatory requirements with confidence.
What to Look for in a High-Performance Sensor
Choose a probe with low-impedance pH glass, a durable platinum ORP electrode, and a large-area reference junction that resists fouling. Built-in temperature compensation, chemically resistant PEEK or Ryton bodies, and industry-standard outputs (4–20 mA, RS485 Modbus) guarantee long-term reliability and easy connectivity.
