Gurley 4190NBreathability 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).

Measurable smoothness, porosity, and softness(compressibility)By replacing different adapters and clamps and calculating the time it takes for a quantitative amount of air to flow through the standard sample area, the porosity or surface leakage can be determined(That is, softness or smoothness). This machine and4110 / 4140The accessories of the type * are the same; In addition, it also includes0.34 lbsWeight, smoothness test clip, softness test clipPunchStorage box for attachments. Suggest purchasing at the same time:4320 Type digital timer, horizontal machine base.
