Optical Dissolved Oxygen Analyzer System

The optical sensor and electro-optical module in one probe. The sensor has a maximum measurement range of 0 – 20.9 % O₂, and a detection limit of 0.007 % O₂ / 3 ppb. It is integrated in a removable sensor cap (OEC), which can easily be exchanged. The mid-range of sensor ideally suited in various applications. The exchange caps are not only available in a version safe for various applications, but also with fast response time, for measurements in aggressive environments, or for reduced air bubble formation on the sensor. The sensor directly connected to the control unit and have a standard PG 13.5 stainless steel thread for easy integration at the measurement site. As a digital interface these probes use RS485  and have 4 – 20 mA analog output. A serial communication protocol is offered for data exchange between the sensor and a PC or other host unit. For initial operation and adjustment of the 4 – 20 mA output the software can be used.
