Economical Double Controller for Redox and pH is suitable to carry out measurement of Redox and pH in industrial processes, with continuous readings on digital indicators. Suitable for wall mounting ready to use.

 

Available compinations:

 

  • pH 0÷14,00 / Rx ±1500 mV
  • pH 0÷14,00 / CD 0÷20 mS
  • pH 0÷14,00 / Flow 9.999.999 l/h
  • CD 0÷20 mS / Flow 9.999.999 l/h.

 

This Economical Double Controller for Redox and pH gives both a valid, low cost measurement and requlation system for large or small industrial and ecological plants, and they can be used as 0/20mA or 4/20mA visualized transmitter for field applications.

 

Relay output for each parameter: Set Point 2 (max. resistance load: 10 A 250 VAC).

 

Two (2) Digital Displays with high efficency blue leds with 2 lines of 16 digits per line, allows the conteporaneous visualization of 2 parameters: chemical measure and temperature.

 

Using the programming menu, it is possible to select the available measurement scale to ensure operating versatility with a single instrument.

 

Instrument Recognises the buffer solution (pH and Redox) and completes the calibration suspending the dosage (HOLD) and showing the electrode’s effciency in %.
