918-204- a rotational viscometer for measuring the rheology of cement slurries. Zemanta one api paginates list views using marker offset pagination by byko-visc DS | Stormer Viscometer | Rotational Viscometers INTRINSIC VISCOSITY ONLINE RHEOMETER – viscotec. Caruthers Park Construction. Rotational viscometers are relatively easy to use but their measurement inaccuracy is at least ±10%. All types have some form of element rotating inside the liquid at a constant rate. One common version has two coaxial cylinders with the fluid to be measured contained between them.

For a specific temperature, scorch time describes how long it will take the material to vulcanize. Rotational viscometer is a device that collects data on materials viscosity performance under various temperature conditions. The rotational viscometer fundamentally is of two parts- one is the head component with a motor and the other is spindle that is motor-powered.

Rotational viscometers are much more expensive but, at the cheaper end of the range, the Brookfield viscometer is extremely useful and popular. As the viscometer became more sophisticated, it became possible to program them, and to take a fluid through a shear stress–shear rate cycle, to increase or decrease the shear rate at fixed rates or to hold at a constant shear rate for a fixed time.

The continuous rotation of the spindle ensures calculations are … Rotational viscometers work by getting the measurements of the torque on a vertical stand that moves the spindle in a rotational direction. The rotation of the spindle is usually proportional to how viscous the sample is. Rotational viscometers are used to measure viscosity. Myr Viscometers V1 and V2 are classic rotational viscometers for the fast determination of viscosity according to following standards: BS: 6075, 5350 ISO: 2555, 1652 ASTM: 115, 789, 1076, 1084, 1286, 1417, 1439, 1638, 1824, 2196, 2336, 2364, 2393, 2556, 2669, 2849, 2983, 2994, 3232, 3236, 3716 This precision Rotational Viscometer is user-friendly and easy to program, simply select a Spindle and the preferred Rotation Speed and with the touch of a softtouch button the viscosity values in cP and in mPa·s of your samples are presented on the large LCD display with backlight comfortable to read under different light conditions. Rotational viscometers are much more expensive but, at the cheaper end of the range, the Brookfield viscometer is extremely useful and popular.
