Based on the scattered light measuring principle, the RM230 detects dust concentrations within a range of < 0.5 to 200 mg/m³ (< 2.2e-4 to 0.087 gr/ft³). Suitable device versions with different measuring penetration depths are available for output of representative measurement results.

The highly flexible RM230, with its robust design, is ideal for use in harsh industrial environments, e.g. for measurement in clean gas uptstream of electro-static precipitators or fabric filters, for monitoring of exhaust and fresh air systems ofr for protection of gas turbines.
