A rheometer is a laboratory device used to measure how a liquid and slurry flows in response to an applied force. It is used for liquids or fluids that cannot be determined by one value of viscosity and therefore require multiple parameters to measure. Rheometer measure the rheological property of the liquid .The property of rheometer to allow even small sample of the product and continuous measure of the rate of deformation, which pave the way for rheometer in the market.
