Measuring Device for Dust Concentration D-R 300-40
| Besonders empfindliches Messgerät für geringste Staubkonzentrationen, speziell in Müllverbrennungsanlagen
|  |
|
Features
|
|
|
|
|
In-situ measurement directly in the flue gas flow
|
|
|
Automatic system tests and correction of measured values
|
|
|
Self-calibration in 4-h cycle
|
|
|
Optics and electronics in a hermetically sealed unit - no smoke gas can enter device
|
|
| Maintenance-friendly, thanks to optimal purge air conduction in front of the heated optical end plates
|
|
Direct access to all parameters via the operator display |
|
| Automatic measuring range selection in accordance with 17. BImSchV. in relation 1:3:9.
