Scattered light dust measuring devices
DUSTHUNTER SP100

Probe design with forward scattered light measurement

Your Benefits

  • Ideal for thick- or double-walled ducts
  • Approved according to EN 15267
  • Low maintenance due to self-monitoring and contamination check
  • Quick installation – no alignment required

Overview

Probe design with forward scattered light measurement

The DUSTHUNTER SP100 is a type-approved measuring device with probe for very low to medium dust concentrations. Installation from one side makes it ideal for thick-walled or double-walled ducts. The measurement is based on the forward scattering of light. An automated check of the zero and reference point as well as a contamination check are on board in the device.

At a glance
  • Installation from one side
  • For very low to medium dust concentrations
  • Automated check of zero and reference point
  • Contamination check
  • Hastelloy measuring probe available for corrosive gases
  • For small to medium duct diameters
  • Device version for explosive zone 2/22 or 1/21
