TUV (India) Certified Double Pass Laser Dust Monitor
The dust monitor is TUV certified, based on double pass principle, equipped with a semiconductor laser. It is excellent for measuring from medium to long distances (0.5m - 10m).
Principle of Operation: The measuring system is based on the Double Pass Transmissometry principle. The light beam crosses the measuring section twice and the trans-receiver unit measures and evaluates the light beam’s weakening caused by the dust content. The optical value will be shown as optical density on analogue display and optical density related to mass value on digital display. Manual calibration check can be done using optical filter.
