pH Sensor

Q&T pH sensors are designed for accurate and reliable pH measurement in a wide range of industrial and water treatment applications. They are available in both standard pH sensors with mV output and digital pH sensors with RS485 and 4–20 mA outputs.

The sensors cover a typical measuring range of 0–14 pH, with an accuracy of up to ±0.02 pH and a resolution of 0.01 pH. Automatic temperature compensation is available to improve measurement stability under changing process temperatures.

Different sensor designs are available for immersion, flow-through, and flow-cell installation, allowing flexible integration into different process systems.

The sensors can also be customized with different shell materials, connection threads, cable lengths, and installation configurations according to the application requirements.

Typical applications include:

  • Water and wastewater treatment
  • Aquaculture and swimming pools
  • Drinking and purified water
  • Chemical and industrial wastewater
  • Food and beverage processing
  • Paper and textile industries
  • Lime and desulfurization processes
  • Hydrofluoric acid and other special chemical applications

For applications requiring direct connection to a control system, the digital models support RS485 and 4–20 mA outputs, making them suitable for integration with PLC, DCS, and other industrial monitoring systems.
