FD20 Redox Electrodes

Yokogawa FD20 Redox Electrodes: A high degree of standardization makes it possible to mount electrodes with DIN dimensions direct in a fitting. For most other types a mounting kit (accessory) is available.
A wide choice of construction materials gives the user the optimal solution for any process considering chemical resistance, pressure and temperature specifications.
The immersion fittings are designed for either pH or ORP (Redox) measurements in tanks, open vessels and drains.
