LYV-8 Digital Kinematic Viscosity Tester
GB 265 / ASTM D445 / IP 71 · ±0.1 °C · 4 Viscometers Simultaneously
The LYV-8 kinematic viscosity tester is applicable to GB 265-88, GB 1814, ASTM D445, IP 71 and other determining methods. A precise imported digital temperature controller keeps the ten-liter homeothermic water bath uniform, while a highlighted digital stopwatch times flow with ±0.1 s accuracy. Four viscometer installing holes allow testing four oil samples simultaneously; the instrument can also serve as a high-viscosity homeothermic water bath for other tests.
