Abstract
A system for measuring gas permeability of membranes under precise temperature and humidity controls, by the use of a gas detector made from a single metallic block, wherein the gas flow passages are virtually entirely confined within the metallic block, and a temperature control passage is provided in the block for stabilizing temperature of the block and the passages therein, at any predetermined temperature. The detector device also includes passages for forming into liquid reservoirs, for providing a controllable relative humidity by passing the test gases through the humidifier passages.
