D-R 220 Optical Opacity Meter/Dust Meter

Represents a new generation of optical instruments. This device is a further development of the D-R 216 opacity meter, and its replacement in the company's model range. The aim of the development was to open up new application possibilities by increasing the measuring range up to 10 m and improving the performance and service characteristics. The optics and electronic components of the measuring part and the reflector are protected by housings made of special high-quality plastic and corresponding to IP65. This facilitates the installation of the flue gas opacity meter and eliminates the need for additional weather protection. The list of enhancements completes the use of a PC communication interface for ease of maintenance and Modbus RTU for data communication.
