High rature viscosity measurement

WebThe resistance of a liquid to flow is called its viscosity. Viscous liquids like syrup and shampoo flow slowly. Less viscous liquids like water and gasoline flow quickly. The viscosity of a liquid usually depends on its temperature. Viscosity generally decreases as the temperature increases. WebWith Testo's globe thermometer, you can measure the radiant heat in a range from 0 to 120°C in accordance with ISO 7243, ISO 7726, DIN EN 27726 and DIN 33403 – essential for norm-compliant comfort level measurement.
