Key Features

• Multi-laser technology for a broad measurement range
• Multi-laser technology for a broad measurement range
  The multi-laser technology provides an extensive range of measurable particle sizes. The single-laser PSA 990 covers a measurement range of 0.2 μm to 500 μm. For an even broader range, PSA 1090 and PSA 1190 have a unique optical design for diffraction analysis, which includes multiple lasers. While PSA 1090 has been designed with two lasers to resolve particles as small as 40 nanometers, PSA 1190 contains an additional third laser to cover the full measurement range of up to 2.5 millimeters. The use of solid state lasers ensures that instruments of the PSA series are ready to measure right after being switched on as nearly no warm-up time is required.
