WÖHLER SM 500 - dust measurement with the latest technology
Time-consuming and expensive evaluations when measuring fine dust are a thing of the past. The robust Wöhler SM 500 dust measuring device provides precise results directly at the measuring location. It could hardly be simpler. The TÜV-certified Wöhler SM 500 dust meter can be used to determine dust concentrations in accordance with the 1st BlmSchV directly at the measuring location. Thanks to the uncomplicated measuring procedure, you can complete all the necessary work in the shortest possible time. The bright color display shows the dust values graphically and numerically during the measurement itself, as well as the O 2 and CO concentrations in the flue gas.
- immediately ready for use
- all in one device including O2 and CO measurement
- precise weighing module - true gravimetric measurement independent of fuel and air humidity
- graphic display during measurement
- integrated flue gas analysis without a collection bag or additional measurement
- no other hidden costs, no contractual obligations
Main uses of the SM 500 dust meter
- dust concentration measurement according to ...
- O2 and CO measurement
