  • Minimum maintenance required
  • Measurements in explosion-hazardous areas

Overview

The reliable dust monitor for potentially explosive atmospheres

Regardless whether it is transmission, opacity, extinction, or dust concentration, with the FW300 Ex, these measurands can be selected freely. Sticky dusts, high gas temperatures, or fluctuating gas velocities, the FW300 Ex also measures under unfavorable conditions with high accuracy practically in real time. A pressure-resistant encapsulated and dust-proof version is also available for applications in explosion-hazardous areas.

At a glance
  • For medium to high dust concentrations
  • Automatic check cycle for zero and reference point
  • Device type for hazardous areas Zone 1, 2 and 22
  • For small to medium measuring distances
