Rotational Viscometer

The Schleibinger Viskomat NT is a versatile rotational viscometer for determining the workability of fine-grained building materials such as cement paste, mortar, fine concrete, plaster etc. with a maximum particle size of 2mm.

The data available includes:
• flow curves and rheological parameters
• temperature dependent workability properties
• stiffening behaviour as a function of time and stirring speed
• effects of concrete admixtures and mineral blending agents on workability

The Viskomat NT is a true speed controlled rate viscometer driven by a high precision synchron motor. each rotation is resolved within 200,000 steps. It allows ramping from 0.001 rpm to 200 rpm in both directions to record flow curves and yield points. The torque up to +- 250 Nmm is measured by a special transducer.

The temperature is measured by a sensor located within the measuring paddles. All the electronics are housed in a separate case. An online display shows torque, time and temperature during the measurement graphically. The electronics has a serial and an Ethernet interface to any PC running the VISKO software. With the Ethernet interface you can integrate the Viskomat NT in any TCP/IP based (10 Mbit, RJ45) network. The Viskomat NT has an built in WWW Server so any WEB browser may be used as user interface, the Viskomat NT can be remote controlled from any workplace in your local area network (from 11/99).
