TUBE – HIGH LEVEL IMPEDANCE TUBE
Mecanum’s High level impendace tube is designed to measure the main acoustic indicators of a wide range of acoustical materials from simple foams to complex multilayers including resistive screens and fabrics.
It covers the frequency ranges 300 Hz to 6000 Hz and reach 155 dB.
PHI – POROSITY AND DENSITY METER
PHI is specifically designed to measure the open porosity and actual apparent density (vacuum) used in acoustic propagation models in poroelastic materials, such as the Biot, Zwikker or Kosten models.
PHI is designed according to the pressure/mass method published in the peer reviewed Journal of Applied Physics.
SIGMA - STATIC AIRFLOW RESISTANCE METER
SIGMA measures the airflow resistivity and permeability of permeable materials
HF SIGMA – HIGH FLOW RESISTANCE METER
The high airflow resistance meter (HF SIGMA) is designed to obtain reliable measurements of the airflow resistance, normalized resistance, resistivity, and viscous permeability in function of flow velocity for a wide range of open cell materials. It automatically detects the appropriate range of airflow speeds and measures pressure drops in function of airflow speed to accurately compute these indicators.
TOR – ULTRASOUND TORTUOSITY METER
TOR is a unique system that uses the most advanced scientific technologies. It measures the tortuosity and the characteristic lengths of porous materials. The tortuosity measured by the TOR system is reflected in the scientific work of Johnson, Koplik and Dashen. This parameter corresponds to the structural factors defined in Biot theory and in Zwikker and Kosten's theory on sound propagation in porous media.
FPS – FABRIC PERMEABILITY SYSTEM
FPS, an essential equipment for the textile industry, which is designed according to ISO 9237, measures air permeability of woven and non-woven fabrics, textiles, and perforated plates. This product includes a verification orifice plate with a verification chart according to ISO 5167-2 as well as the FPS-X software that fully controls the measurement.
