Gravimetric measurements have shown that the entire part of the mass of fine dust below 0.5 µm does not even total one percent. But if the particles are counted, 80% of all particles are in the size range below 0.5 µm. It is not obvious if the particle number or the particle mass has a greater effect on the human ...
Gravimetric measurements have shown that the entire part of the mass of fine dust below 0.5 µm makes up less than 1%. But if the particles are counted, 80% below the size range of 0.5µm. It is not obvious if the particle number or the particle mass has a greater effect on the human health. Therefore it would be useful to have a device ...
Grimm is a leading engineering technology provider undertaking research and design and production of different aerosol spectrometers for research as well as indoor and outdoor air quality monitoring. This powerful instrument gives the user the ability to continuously measure in real time particles in 31 different size channels and present the data ...
Particle number concentration and size distribution as well as dust masses as mass fractions in real-time and at any given location.
The new welas digital 1000 is a powerful and economical light-scattering spectrometer system, which determines the particle concentration and the particle size extremely precisely and reliably. With welas digital 1000, particle sizes can be measured reliably from already 120 nm, as the particularly powerful Xenon high pressure lamp with very high ...
Promo is a light-scattering spectrometer system for particle size analysis and concentration determination that can be equipped with all welas sensors. Using fibre-optic cables, welas sensors – equipped with measurement volumes of different sizes – can be easily attached to the Promo 2000 and Promo 3000 and exchanged at will. These ...
The new welas digital is a flexible, powerful and economical light-scattering spectrometer system, which determines the particle concentration and the particle size precisely and reliably. Using fibre-optic cables, welas sensors – equipped with measurement volumes of varying sizes – can be easily attached to the welas digital 2000 and ...
On the new welas digital 3000, two welas sensors are supplied with one light source and the scattered light pulses are detected by a photomultiplier. This enables a quasi-simultaneous particle measurement at two sampling locations that are up to 100 metres apart. The quasi-simultaneous particle size and particle number determination offers ...
Palas offers the worldwide largest selection of different sensors for the operation at the scattered light spectrometer systems welas digital and Promo. Welas sensors are available for the particle measurement in gases and in liquids. The welas sensors are optimised for particular particle concentrations with measuring volumes of different sizes ...
On the Promo 3000, two welas sensors are supplied with one light source and the scattered light pulses are detected by a photomultiplier. This enables a quasi-simultaneous particle measurement at two sampling locations up to 100 metres apart.
