Digital MK2 Porosity Tester

The Digital MK2 Porosity Tester is a precision porosimeter designed to measure the porosity (air permeability) of fabrics, such as those used in paragliders, hot-air balloons, sails, and other technical textiles. It operates by forcing a defined volume of air through a sample under controlled pressure and measuring the time taken, which is then converted to a porosity value.

Key Features

·         Digital counter displays the elapsed time in tenths of a second.

·         Converts measured time into standardized units such as litres per m² per minute (l/m²/min) using internal or manual conversion.

·         Narrow remote probe option for measuring high-porosity or difficult-to-access fabrics.

·         Lightweight and portable; designed for field or lab use.

·         Powered by 2 × AA batteries (LR6).

·         Memory function: it can recall the last three measurements.
