Scattered light dust measuring devices
DUSTHUNTER SB30

Continuous measurements of low and medium dust concentrations

Your Benefits

  • Easy installation, commissioning, and operation
  • Tried-and-tested measurement, not dependent on gas velocity, humidity, or particle load
  • Cost-effective thanks to easy mounting on just one side; no alignment necessary
  • Very low-maintenance thanks to self-monitoring
  • Demand-controlled maintenance notifications

DUSTHUNTER SB30

Overview

Continuous measurements of low and medium dust concentrations

The DUSTHUNTER SB30 is a measuring device, designed to detect very low to moderate dust concentrations, such as in hot or volatile gases. Measurement is based on the tried-and-tested measurement principle of backward light scattering. Installation is easy and is only carried out on one side of the channel. Two different penetration depths are possible for adapting the measuring device to various channel diameters.

At a glance
  • For low to medium dust content
  • Easy one-sided installation
  • Automatic check of zero and reference point
  • For medium to large duct diameters
