Rollerball viscometer - cod. produto nv2511

Rollerball viscometer - cod. produto nv2511; ; ; the model 1602 rolling ball viscometer is a high pressure precision instrument for determining the relative viscosity of hydrocarbon and related liquid samples at elevated temperature the instrument is commonly known "rolling ball" viscometer. the principles of operation is to measure the time it takes for a metal ball to fall through fluid medium. the resistance to the gravatational pull on the ball is due to the fluid density and viscosity . by measuring roll times of several known viscosity standards fluids, the user can develop calibration curves relating viscosity to roll time (corrected for fluid density). the relative viscosity of the unknown fluid is then determined from the graph the model 1602 viscometer is integrated in the 2370 console along with the model 2353 flash separator model 23341 gasometer, vacuum pump and fluid flow manifold as a comprehensive test bench apparatus.; ; ; ; the model 1602 may also be configured as an individual test system.;
