Gurley 4140NBreathability meter

Quantify air(2.5...30cc)By passing the sample under a fixed pressure and measuring the required time, its permeability can be determined. The fixed pressure is generated by a standard weight cylinder, and the sample is clamped between a standard gasket with a small hole in the middle, which can slide inside the oil sealed airtight cylinder. The center hole of the gasket is divided into φ1.0' (Standard area)、 φ0.25'perhaps φ0.1' (All are optional).

This machine is 4110 Type matched with 'load suspension components'. At zero load or with added suspension0.34lb (choose and buy)、2.0lb(standard configuration)When using weights, it can generate 3.2、9.6、40.5psiPressure. Suggest purchasing at the same time:4320 Type digital timer, horizontal machine base.
