    Supercritical fluids (SCFs) are being investigated as a dielectric medium for their low viscosity, high dielectric strength, high heat transfer capability, low cost, and environmental friendliness. This paper introduces a straightforward, cost-effective, and commercially available sensor to measure SCF viscosity for the characterization of the dielectric medium. Quadratic and cubic fitting between the sensor current output and viscosity of He, H2, CO2, SF6, and N2 were made in the ambient lab environment. Experimental temperatures range from 19.3°C to 22.0°C and fluid pressure from 0.1 MPa-1.5 MPa. This manuscript introduces preliminary data for a methodology to correlate SCF viscosity to the output signal of a commercially available sensor. This will enable viscosity measurement of mixtures of dielectric fluids.
