N2 - We have developed the use of quartz tuning forks for thermometry in normal liquid He-3. We have used a standard 32 kHz tuning fork to measure the viscosity of liquid He-3 over a wide temperature range, 6 mK <T <1.8 K, at SVP. For thermometry above 40 mK we used a calibrated ruthenium oxide resistor. At lower temperatures we used vibrating wire thermometry. Our data compare well with previous viscosity measurements, and we give a simple empirical formula which fits the viscosity data over the full temperature range. We discuss how tuning forks can be used as convenient thermometers in this range of temperatures with just a single parameter needed for calibration.
