Optrode

Optical sensors for titrations with photometric endpoint recognition.

 
6.1115.000 Optrode

Sensor for titration with photometric endpoint recognition.


  • Eight wavelengths: 470, 502, 520, 574, 590, 610, 640 and 660 nm
  • 100% solvent-resistant through glass shaft
  • Compact and space-saving
  • Very simple cleaning
  • Simple change of wavelengths

Both new and existing titration systems can be furnished with the Optrode. The power supply is provided directly through the USB interface of a Metrohm instrument (Titrino plus, Ti-Touch, Titrando, USB sample changer). With older models without a USB interface, the power supply can also be provided by means of an optional USB power supply unit.
