Description

Promo® 2000 is a light-scattering aerosol spectrometer system for particle size analysis and concentration determination that can be equipped with all welas ® sensors .

On Promo® 2000, the welas® sensors equipped with different measurement volumes, as required, can be easily connected via fiber optic cables and interchanged as needed. These sensors allow reliable measurement in the concentration range from < 1 particle/cm3 to 106 particles/cm3 in gases.

Unique are up to four measuring ranges in only one device:

  • 0.2 µm – 10 µm
  • 0.3 µm – 17 µm
  • 0.6 µm – 40 µm
  • 2 µm – 100 µm (additionally for sensors 2300 and 2500)

Promo® 2000 is famous for up to 128 size channels per measuring range and a concentration range from < 1 particle/cm3 to 106 particles/cm3.

A touch display ensures user-friendly operation. Measurements can be started quickly, and all data, such as the current number distribution and the number concentration, and 24 further statistical values, can be evaluated and displayed in real-time.

Measurements are performed continuously with Promo® as a standalone measuring device (i.e., without an external computer)® as a standalone measuring device (i.e., without an external computer), and measurements are performed continuously. All incoming data can be stored with a maximum temporal resolution of 1 s. Promo® 2000 can therefore measure and save data over weeks independently. For data transfer, Promo® can also be integrated into a company network.

Promo® 2000 has a standard interface and can be controlled by a process control system or a simple Labview program. For this reason, Promo® 2000 is especially well suited for control and monitoring applications. Temperature, humidity, and pressure sensors can be connected.

Palas® offers remote maintenance for the device and data access via www.palas.de/user.

Promo® 2000 offers a new, fast 20 MHz signal processing processor, which analyses the progression of each particle signal. This makes it possible to recognize coincidental events in light scattering measurement technology at the individual signal and correct them (according to Dr. Umhauer / Prof. Dr. Sachweh). This way, increasing the maximum concentration limit is up to 106 particles/cm3 (welas® 2070 sensor). Also, low concentrations of < 1 particle/cm3 with the welas® 2500 sensor lead with the welas® 2500 sensor lead to higher measuring accuracy.

High classification accuracy and high particle size resolution are guaranteed by the following special features (see Graph 1):

  • White light and 90° light-scattering detection ⇒ Unambiguous calibration curve
  • Patented T-aperture ⇒ No border zone error
  • New digital individual signal processing ⇒ Coincidence detection and correction of the individual signal making it possible to measure higher concentrations
