Description

The Palas PROMO 2000 series aerosol spectrometers are arguably the most advanced portable aerosol spectrometers of their type in the world. Offering an incredibly wide particle size range, 128 high-resolution particle size channels, a large color touch screen display, and many other features, the PROMO 2000 is the ideal tool for the serious dust/particle monitoring professional. The unit provides amazing high-resolution particle concentration and size measurements over its entire particle size range.

Depending on the composition of the aerosol to be measured (i.e. the carrier gas component and the particle material), pressure and temperature changes in the carrier gas can significantly influence the particle size distribution (i.e to condensation or evaporation). For this reason, the PALAS WELAS aerosol sensors (2070H, 2070HP, 2100H, 2100HP, 2200H, 2200HP, 2300H, 2300HP, 2500H, 2300HP) are equipped with a heatable and, as required, pressure-tight cuvette to ensure isobaric and iso thermal sampling into the sensor’s measurement volume.

The PROMO 2000H model variant also offers heating regulation for temperatures up to 250 °C for the aerosol sensors with heatable cuvette. The PROMO is usually calibrated for the operating volume flow. In the PROMO 2000H version, regulation of the sampling volume flow is performed independently by the customer taking the temperature and pressure into consideration.

Palas Welas Series Sensors

The Palas Promo 2000 series may be used with any of the different PALAS Welas series particle sensors, as shown in the image above. These Welas series particle sensors have different measurement volumes and are connected to the PROMO 2000 control unit via fiber optic cable (lengths up to 30m). The sensors sit directly on top of the control unit which provides the BEST possible measurements, as it eliminates sample tubing and thus eliminates any particle losses as a result thereof. Please refer to the individual specification sheets for the Welas series sensors or call us for more information. The user can select between 4 different measurement ranges in one powerful instrument.

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

Such a Versatile Device

The large color touch screen display ensures user-friendly operation. Measurements can be started easily, and all of the data, such as the current size distribution and the number concentration, as well as 24 further statistical values, can be evaluated and displayed in real-time. This powerful unit can be used in the field or laboratory as a complete standalone instrument, without computer control. It can also be used with an external computer. It can be used for continuous ongoing measurements or for short tests/experiments. All the incoming data can be stored with a maximum temporal resolution of 1 second.

The Promo 2000 can, therefore, measure and save data over large periods of time independently. For data transfer, PROMO 2000 can also be integrated into a company network. The PROMO 2000 also has a standard interface and can be controlled by a process control system or by a simple Labview program. For this reason, the PROMO 2000 is especially well suited for control and monitoring applications. Temperature, humidity, and pressure sensors can also be connected.

New Measurement Technology

The PROMO 2000 series 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. This way it is possible to increase the maximum concentration limit up to 10 to the power of 6 particles/cm3 (Welas 2070 sensor). Also in low concentrations <1 particle/cm3 with the Welas 2500 sensor, which leads to a higher measurement accuracy.
