The density of high viscosity working liquids (-1, LEYBONOL LVO 500, and Alkaren-D24) for diffusion vacuum pumps have been measured over the temperature range from (273 to 473) K at atmospheric pressure. The measurements were made using a new designed densimeter based on hydrostatic weighing method. The combined expanded uncertainty of the density, atmospheric pressure, and temperature measurements at 95 % confidence level with a coverage factor of k = 2 is estimated to be 0.02 %, 1.0 %, and 0.02 K, respectively. To confirm the reliability, accuracy and correct operation of the densimeter, the density of pure n-heptane, ethane1,2-diol
