A concentration measuring method for a binary gas system, which was based on the viscosity measurement, was investigated. The method utilizes two types of pressure gauges, a capacitance manometer which depends just on pressure and a quartz friction pressure gauge which depends on both viscosity and pressure of a binary gas. The concentration of the binary gas can be estimated from the viscosity because the viscosity is given as a function of concentration of the binary gas. Firstly we applied the pressures-observing system to evaluate concentration of ozone in an O<SUB>3</SUB>/O<SUB>2</SUB>gas mixture. The results indicated that this method allows a concentration measurement of ozone with an accuracy of<I>Δ</I> <I>Cozone</I> = 0.2 vol%, near atmospheric pressure. Secondly, we used an impedance measurement system of a quartz oscillator and we estimated the accuracy at <I>Δ</I> <I>Cozone</I>=0.05 vol%.
