A quartz friction vacuum gauge (QF gauge) is based on the fact that the resonance impedance of a quartz oscillator is proportional to the frictional force of ambient gas. The first model of the QF gauge, which was developed by the authors as a wide range pressure monitor, has the minimum measuring pressure of 0.01 Torr with an accuracy of the order of 10%. To lower the minimum measurable pressure, we developed a sensing head consisting of a tuning fork oscillator with higher sensitivity fixed on a temperature‐stabilized metal rod and a digital readout circuit. The performance of the gauge was evaluated from results of measurement of pressure dependence, temperature variations, and fluctuations of the gauge output, which is proportional to the resonance current of the oscillator. It was confirmed that an error in measurement by the gauge is within ±10% for pressure from 0.001 to 1000 Torr.
