With the use of strain‐gauge pressure transducers, an improved constant volume apparatus has been constructed for the measurement of isothermal permeabilities of gases from thermo‐osmosis experiments. Permeabilities are reporducible to about ±5% accuracy and compare favorably with those obtained by alternative techniques. Revised values are presented for the permeability coefficients of the noble gases in rubber.
