- Measurement independent of gas velocity, humidity and particle charge
- Approved according to EN 15267
- Low maintenance due to self-monitoring
Overview
The type-approved dust measuring device with reverse scattered light measurement
The DUSTHUNTER SB100 is a type-approved measuring device for dust at very low to medium concentrations in challenging applications, e. g., in hot or corrosive gases. The measurement is based on the backward scattering of light. Installation is from one side only. Two different penetration depths are possible. Automated compensation of background radiation, therefore no light absorber required. An automated check of the zero and reference point as well as a contamination check are on board in the device.
At a glance
- For very low to medium dust concentrations
- One-sided installation
- Contamination check
- Automated thorough check of zero and reference point
- Automated compensation of background radiation, therefore no light absorber required
- For medium to large duct diameters
