VEREWA F-904-20 Dust Concentration Monitor
Brand: DuragDust monitor especially for wet flue gases and for the monitoring of blast furnace gas.
Exhaust gas laden with particles is extracted from the duct and diluted.
The sampling gas passes a filter. AC source irradiates the particle laden filter spot.
The absorption by the dust is measured and compared with the empty filter spot.
Features- Automatic zero correction
- Pre-calibrated, unaffected by particle size, colour or moisture
- Isokinetic sampling
- Measurement of very low dust concentrations
