| Measuring principle | extraction of sample gas, dilution and heating to vaporize H2O aerosols. Consequent measurement of light intensity being scattered in forward direction by dust particles |
| light source | laser diode, red 650 nm |
| type | in situ, mounted at stack, probe in contact with sample gas |
| system components | D-R 820F P probe incl. extractive system D-R 820F blower unit D-R 820F SU Supply, control and display unit |
| measuring range | can be parametrized |
| expanded uncertanty acc. to EN 14181 / EN ISO 14956 / EN 15267-3 | better than 1,5 mg/m3 at particle size 1-2mü |
| output range | scaling of scattered light values in mg/m3, assigned to analog output, range switching to 2nd range as option (ratio 1:3), display of measured values in mg/m3 |
| process connection | flange similar to DN80, PN6, pitch circle 150mm, tube ID = 100mm |
