Enquiry Item

Continuous water quality monitoring of pH/ORP

The Q46P pH/ORP monitor provides the combination of durability, accuracy, and versatility required for virtually any pH monitoring or control application.

The Q46P pH monitors can be paired with our Q25 differential sensors. For this type of sensor, the silver/silver chloride reference element has been replaced by a pH sensitive glass electrode identical to the measuring electrode. This second glass electrode is housed in a chamber filled with pH 7 buffer which provides a stable reference. A high surface area reference junction electrically connects this reference system to the pH measuring element. The result is that pH is measured by the voltage difference between the two pH sensitive glass elements.


Features and Specifications:

  1. Optional with automatic pH or ORP sensor cleaning. (Q-blast)
  2. Measuring range: 0 to 14 pH, -1000 to +2000 mV
  3. AC or DC Power Options.
  4. Digital Output Options. (Profibus DP, Modbus RTU, or Ethernet IP)


The Q46P pH/ORP monitor is available for a wide range of applications including:

  1. Potable water systems
  2. Water reuse systems
  3. Cooling towers
  4. Aquariums
  5. Wastewater treatment effluents
