N2 - Commercial quartz oscillators of the tuning-fork type with a resonant frequency of similar to 32 kHz have been investigated in helium liquids. The oscillators are found to have at best Q values in the range 10(5)-10(6), when measured in vacuum below 1.5 K. However, the variability is large and for very low temperature operation the sensor has to be preselected. We explore their properties in the regime of linear viscous hydrodynamic response in normal and superfluid 3He and He-4, by comparing measurements to the hydrodynamic model of the sensor.
