Overview

The DUSTHUNTER SP30 is a measuring device which reliably detects very low to high dust content. The measurement is based on the forward scattering of light and is independent of the gas velocity and particle charge. The automated monitoring of the zero and reference point ensures a high level of accuracy.

Thanks to its compact design, the DUSTHUNTER SP30 is available as an independent measuring device but also with an integrated purge air unit and MCU control unit for additional functions as an option. The installation is carried out on one side of a duct, whereby several mounting options and probe lengths are available. The measuring device is highly versatile, e.g., for process optimization or intelligent filter diagnostics and monitoring.
