EziLab offers the Kinematic Viscometer EZL-KV101, a capillary viscometer bath that measures kinematic viscosity in centistokes by timing how a fluid flows through a calibrated capillary under gravity. Choose it over a rotational viscometer when petroleum or lubricant methods specify kinematic results rather than dynamic viscosity. The water bath controls temperature from ambient to 100°C within ±0.1°C, covering the 40°C and 100°C test points commonly used for oils and viscosity index calculation. A Pt100 RTD sensor, electric heating, and a 1200 rpm stirring motor keep bath temperature uniform around each tube, and the viewing area lets operators watch the meniscus pass the timing marks. Six capillary tubes with 0.6, 0.8, 1.0, 1.2, 1.5, and 2.0 mm inner diameters cover thin to viscous samples, and the built-in timer records flow time from 0 to 9999.9 seconds. Mercury reference thermometers for 0 to 50°C and 50 to 100°C, capillary clamps, stoppers, and cleaning tools all ship as standard. Petroleum laboratories test base oils, engine lubricants, hydraulic fluids, and fuels, chemical plants verify resins and solvents, pharmaceutical labs check syrups and liquid formulations, and food processors measure oils and liquid ingredients. Mercury-filled glass raises handling and disposal questions for some sites, a point to settle internally before comparing the Petroleum Testing Equipment category and Kinematic Viscometer range.
