Description
During the sample taking of hot aerosols, particle condensation from the gas phase may occur if the aerosol cools down. To avoid that effect, the whole sample taking unit including the aerosol sensors, sampling lines and dilution systems must be heated. The sample taking should be isothermal to avoid changes of the particle concentration and the particle size distrubution.
The heatable sampling tubes PS 1000 / PS 2000 and PS 3000 can be heated up to 120 °C and can be adapted to the heated welas® aerosol sensors easily. The heating control is part of the delivery content.
For heating temperatures up to 250 °C Palas® offers the variation with the articles PS 1000 HT / PS 2000 HT and PS 3000 HT.
