Dust monitor especially for wet flues - emission temperature under dew point - and for the monitoring of blast furnace gas

Features

Automatic zero correction

lPre-calibrated, unaffected by particle size, colour or moisture

Sample gas flow regulated at 1 - 3 m3/h

Isokinetic sampling

Optional dilution sample probe for high concentrations or after wet scrubbers

Heavy metal analysis possible

Special model with measuring chamber purging and CO-TLV monitoring during dust monitoring of blast furnace gas

Applications

Coal and oil-fired power stations

Waste incineration plants (municipal waste, industrial waste and hazardous waste)

Sewage sludge incineration plants

Emission dust measurement after wet scrubbers or in very wet exhaust gases

Heavy metal analysis

Measurement of very low dust concentrations in emissions

Emission dust measurement in inaccessible flues with small diameter

Dust concentration measurements in process applications
