Intelligent pH & ORP Transmitter / Controller System – TX2000


Intelligent pH & ORP Transmitter / Controller System – TX2000

Intelligent transmitter / controller of pH and ORP with programmable process control, ideal for in-line / on-line applications.

The transmitter box can be panel or wall mounted. A large digital screen displays temperature, pH / ORP values.

Sensorex pH / ORP sensors provide reliable real-time monitoring of these important parameters. They can be swapped very easily, too.


  • Waste water
  • Process water
  • Wash water
  • Drinking water


  • Controller box features two relays, one wash control, two each 4-20mA outputs for pH and Temp or ORP and Temp
  • Consistent and repeatable monitoring and process control with sample averaging for increased stability
  • Highly accurate measurements: solution ground input eliminates measurement errors caused by reference ground potentials
  • Compatible with  Sensorex combination-style pH / ORP sensors (with tinned leads)
  • Self-cleaning sensor options available
  • Easy calibration using a maximum of 3 Tech or NIST buffers
  • Power: uses 11- 240 V AC

Examples of Electrodes available:

  • S656CD – Process pH sensor cartridge for use with S675 hot tap assembly – insertion / wet tap assembly
  • S8000CD – Quick change replacement sensor cartridge for S8000 series pH kits – modular series
  • S272CD – Online process pH sensor – convertible submersion with durable PPS bodies
  • ORP options also available in all the above examples
