3G micro



A 3G can measure more than 256 discrete pressure points to provide unbeatable granularity.

Porometer 3G micro

The Porometer 3G micro is the capillary flow porometer with small-to-medium pore size capability, and customizable flow rate options. The standard pressure capability of up to 100 psi / 7 bar allows for pore size distributions in the range of 0.09 µm up to >90 µm to be measured easily and accurately. With a choice of flow rate ranges (20, 100 or 200L/min) the 3G micro is especially suitable for a wide variety of woven and non-woven materials having narrower pore size distributions, and/or as an entry level porometer. The 3G micro conforms to ASTM standard methods D6767, E128, F316, and similar.
