Visco city bath manufacturers in Ahmedabad Brand: Hema The viscosity of a fluid refers to its resistance to flow, which is affected by temperature. Viscosity baths help to minimize the impact of temperature fluctuations on this important property. Many liquids become more fluid as their temperature rises, making precise temperature control vital to testing their true viscosity. The bath helps maintain a constant environment, so the viscosity measurements are not skewed by external temperature variations. This is particularly important in quality control and product development.
