Palas particle size spectrum

Palas particle size spectrumIt is a high-precision instrument used for real-time measurement of aerosol particle size distribution and concentration, widely used in aerosol research, air quality monitoring, filter testing and other fields.
Measurement technology:

Palas particle size spectrumEquipped with a new 20 MHz fast signal processing processor that can analyze the process of each particle signal. In this way, coincidence events on a single signal can be identified and corrected in light scattering measurement technology (according to the theory of Dr. Umhauer/Professor Sachweh). This can increase the maximum concentration limit to 106 particles per cubic centimeter (welas) ® 2070 sensor). Similarly, using welas at low concentrations of<1 particle/cubic centimeter ® A 2500 sensor will also achieve higher measurement accuracy.

The following special features ensure high classification accuracy and high particle size resolution (see Figure 1):
White light and 90 ° light scattering detection
⇒ Clear calibration curve
• Obtain a professional T-aperture
⇒ No boundary area errors
New digital single signal processing

The coincidence detection and correction of individual signals make it possible to measure higher concentrations

The characteristic of Palas particle size spectrum is its high counting efficiency starting from 0.2 µ m!

Palas particle size spectrum has the characteristics of fiber optic technology. welas ® The aerosol sensor uses a Promo control unit and is connected through a fiber optic cable with a maximum length of 30 meters. Simply install the sensor directly at the sampling location to reduce particle loss in the long sampling pipeline.
