In order to check the suitability of Vacuum Handling Devices, the POROMETER was designed by the Probst engineers. It facilitates metering the air permeability of concrete products.

To take measurements, the POROMETER is connected to a powerful compressor with minimum suction volume about 400 l/min (14 ft³/min) and air tank approx. 100 l (3,5 ft³). After setting the POROMETER by using a steal plate as reference level, the suction plate of the metering device is put on the concrete element which should be measured. Reading the volumetric flow rate, the concrete
elements can be classified into 5 categories of air permeability (classification see
chart below).

The readings are taken by checking the position of the upper end of a floating-type flow meter, which is floating in the transparent measuring tube according to the volumetric flow rate. The categories of air permeability provides indication about the type of Vacuum Handling Device which is best to use for installing these kind of elements.


  • Measuring range m³/h (ft³/h): 0 – 6 (0 – 210)
