  • On-line sensor checking monitors integrity of membrane
  • Event logbook in software
  • Four fully configurable SPDT contact outputs
  • Two fully configurable mA outputs
  • Built-in PI controller
  • Easy to use EXA control panel
Application Note
Overview:

When used to measure the dissolved oxygen in an aeration tank, sensors tend to quickly become contaminated and need frequent cleaning. A cost-effective solution to this problem has finally been found with the development of the Yokogawa DO402 Dissolved Oxygen Converter system. 

Overview:

The detectors used to perform dissolved oxygen (DO) measurement in oxidation ditch type sewage treatment plants tend to become dirty quickly and require frequent cleaning. It has been d ifficult to remedy this problem inexpensively. One solution that significantly reduces the sensor maintenance workload is the use of float holders.

Industries:
Overview:

Pigment producer manufacture produces pigments to supply to paints, plastics, inks, construction, textile and cosmetics manufacturers etc. The pigments come under wide range - general purpose grades, high performance, and specialist hard-to make colours and effect pigments.
