Scope This instrument conforms to astm d445 standard, the instrument is used to measure the kinematic viscosity of liquid petroleum products (newton liquid) at a constant temperature. Kinematic viscosity is the product of the viscosity of the liquid at a constant temperature and the density of the liquid at the same temperature. Features 1, imported omron temperature controller, lcd, temperature accuracy of ± 0.1 ?. 2, using a hard glass tank, good insulation properties, the specimen was observed clear. 3, using a desktop, one machine design approach, the instrument overall good, easy to use. 4, use of electric stirring device, temperature uniformity bathtub 5, the instrument comes with expert self-tuning capabilities, more precise temperature control Technical parameters 1 power supply: ac 220v ± 10%, 50hz ± 5%. 2 heating power: 1800w. 3, stirring motor: power 6w; speed 1200r / min. 4, temperature range: room temperature ~ 100 ?. 5, temperature control accuracy: ± 0.1 ?. 6, constant temperature bath: capacity, 20l; 7, the use of environment: temperature -10 ? ~ + 35 ?, relative humidity
