AVL Micro Particle Monitor

Ever stricter statutory requirements call for extremely reliable and sensitive measurement methods for determining the exhaust volume from vehicles or engines. A dynamic, high-resolution particulate measuring device is therefore also needed in diesel and gasoline engine development work.

The AVL Micro Particle Monitor is designed for the continuous measurement of low particulate concentrations in diluted exhaust from IC engines. Being able to constantly observe the particulate curve makes it possible to reduce emissions to below the statutory targets over the entire test curve. In other words, it guarantees efficient development work.
There is generally good correlation with gravimetric filter measurements, but the reproducibility of emissions containing mainly particulate in nucleation mode or particulate with a high percentage of soluble substances is generally not so good. In this case, the soluble content can be eliminated with a thermodenuder.
