The Viskomat XL from Qualitest is a versatile rotational viscometer for determining the workability of building materials such as mortar, cement and fresh concrete (up to 8mm grain size). This new instrument is the outcome of our long experience with Rheometers for mortar and fresh concrete.
Viskomat XL has been developed to fill the gap between our Viskomat NT for mortar and paste with a specimen volume of 360 ml and our con¬crete Rheometer BT2 with a sam¬ple vol¬ume of 20 l. The High precision synchronous motor controls the speed of the specimen vessel from 0.001 to 100 rpm in the direction, clock wise or anti clockwise. The speed may be defined in several steps either linear increase or decrease.
The Viskomat XL has a high torque range from 0-500 Ncm with a resolution of 0.05Ncm and accuracy better than 0.2Ncm. Qualitest also offer optional sensors to increase the torque range to 1000Ncm and an accuracy of 0.8Ncm.
The temperature is controlled by the circulating coolant liquid between the dual walls of the specimen container, while the temperature is measured with a RTD mounted inside the shaft of the probe. Our Viskomat XL does have an option to be operated in shear stress control mode, such that the speed is automatically controlled to achieve the predefined torque.
To meet the present trend, the Viskomat XL is designed in such a way that it could be controlled via network interface. Simply connect the instrument to a PC and start the Internet Explorer for full control and data transfer.
