Digital optical sensors for dissolved oxygen in hygienic applications
The high-quality sensors enable reliable measurement of all dissolved oxygen concentrations from the trace level to the saturation level. Both versions have been especially developed for hygienic as well as demanding applications and represent different measuring ranges. Common field devices and process control systems can be connected via an integrated analog and digital interface. The connection to the intelligent, bus-compatible JUMO digiLine system is made via Plug and Play.
