Key Features

  • 200nm to 100µm wide particle size range
  • Dual aerosol sensors for simultaneous multi-channel measurements
  • Up to four selectable measurement ranges in the one device:
    – 0.2µm to 10um
    – 0.3µm to 17um
    – 0.6um to 40um
    – 2µm to 100um
  • Up to 128 particle size channels per measuring range
  • 1 particle/cm3 to 10 to the power of 6 particles/cm3 particle concentration range
  • 5 LPM flow rate
  • Digital 20Mhz processor with 256 raw data channels
  • Calibration curves for different refractive indices
  • Very high and reproducible counting efficiency rate starting at 0.2µm
  • High temporal resolution down to 10ms
  • Optical fiber technology
  • Measurements in potentially explosive environments
  • Ultra long life light source technology
  • Extensive PDControl and FTControl software provided
  • Simple operation
  • Calibration, cleaning and lamp replacement can all be performed independently by the customer
  • Low maintenance
  • Highly reliable and easy to use

Welas Digital 3000 Series Options

  • Welas Digital 3000      (standard model)
  • Welas Digital 3000-H   (with heating regulation up to 250 degrees C for Welas aerosol sensors)
  • Welas Digital 3000-P   (with automatic regulation of sample volume flow by the Welas sensor under over pressure up to 10 bar)
  • Welas Digital 3000-HP (the same features as the 3000-P plus operating temperature up to 120 degrees C)

The latest Palas Welas digital 3000 series sensors are supplied with one light source and the scattered light pulses are detected by a photo multiplier. This enables a quasi-simultaneous particle measurement at two sampling locations that are up to 100 meters apart. The quasi-simultaneous particle size and particle quantitative determination offers particular advantages for characterizing separators with fluctuating raw gas concentrations. With the Palas Welas Digital 3000, the user effectively has two scattered-light spectrometers in one device with the same device characteristics:

  • Particle size resolution capability
  • Particle size classification accuracy
  • Counting efficiency
  • Zero counting rate

Typical Applications

  • Separation efficiency determination of car cabin filters, engine air filters, room air filters, compressed air filters, vacuum cleaner filters, cleanable filters, electrostatic precipitators, oil separators, cooling lubricant separators, wet separators, cyclones and other separators
  • Isothermic and isobaric particle size and quantity determination. For example, in the automotive, chemical, pharmaceutical and food industries
  • Investigation of fast, transient processes
  • Testing smoke detectors
  • Particle measurement for cloud formation
  • Emission measurements
  • Respiratory function: inhalation / exhalation (particle size and number)
