OMD41
|
|
| |
Dust and Opacity Monitor For monitoring dust concentrations in industrial plants - even across long measurement paths. The OMD41 is a transmissiometer that operates according to the autocollimator principle. It is performance-tested pursuant to the German Clean Air Regulations, Federal German Pollution Control Act (13th Implementing Ordinance), GOST and the US EPA guidelines.
Applications Asphalt mixing plants; cement manufacture; monitoring/controlling electronic filters; power stations, steel and glass industry; monitoring technical equipment downstream of filter systems
