PH ORP Analyzer

The pH ORP analyzer includes a pH controller also called a pH transmitter and a pH sensor or ORP sensor. pH is also called acid-base value, which directly reflects the concentration of hydrogen ions in water. When the pH is greater than 7, the water is alkaline, when the pH is equal to 7, the water is neutral, and when the pH is less than 7, the water is acidic. There are many factors that affect the pH value of water, and temperature is one of them. Therefore, when measuring the pH value, it is necessary to compensate for the temperature. The pH ORP analyzer developed and produced by Daruifuno is a reliable product. We provide analog and digital two types pH ORP analyzers.


  • The pH controller is compact in shape, with small size or large size, which can meet various installation needs of customers, and we also provide matching installation accessories.

  • Since temperature has an impact on pH measurement, for more accurate measurement, the pH meter has temperature monitoring and automatic temperature compensation functions, which can be manually or automatically compensated. The matching pH sensor has a built-in temperature unit, NTC10K, PT1000, etc.
  • The pH orp analyzer has 2 SPST relays with high and low settings, which can control dosing, cleaning and temperature.
  • 2-way 0/4-20mA circuit output, which can output pH or ORP value and temperature value.
  • The online pH meter also has an RS485 interface and supports the Modbus communication protocol.
  • In addition, the pH ORP analyzer also has functions such as password setting and test maintenance.
  • The enclosure protection grade is IP66, and it can be used continuously outdoors.
  • The large-sized pH meter also has time and history functions.

The pH control process widely exists in petroleum, chemical industry, pharmaceutical, papermaking, wastewater treatment and water supply treatment. In industrial production, the pH value must be strictly controlled within a specific range, otherwise it may cause product quality degradation, waste of raw materials, production failure, and even environmental pollution. Therefore, the pH value can be controlled within a certain range by using a pH orp analyzer.
