Compensating vibration viscosimeter

Conclusions The advantages of this instrument consist of its reliable transducer and its readings which are not affected by variations in the signal amplitude or by the instability of the electronic circuit's amplitude transfer factor. The instrument has a measurement range of 0.004 to 2 N·sec·m^–2 and a measurement error of ±2% over the greater part of this range.Translated from Izmeritel'naya Tekhnika, No. 4, pp. 62–64, April, 1969.
