System Integration Engineering & Fabrication
• D-R 320 The new generation scattered light dust monitor
unique feature of the D-R 320 is the automatic background light compensation with means of a patented optical system with dual detector. This allows for an easy and quick Installation without any adjustment. A light trap is not required.
• D-R 290 Optical opacity / dust monitor 2nd generation
The D-R 290 operates using the double-pass method according to the auto-collimation principle. The light beam traverses the measuring path twice. The attenuation of the light beam by the dust content in the measuring section is measured and evaluated.
