Laboratory Viscometers DHJ-5S+DH-25A
Laboratory Viscometers DHJ-5S+DH-25A

When the temperature deviation is 0.5°C, the deviation of the viscosity value of some liquids exceeds 5%, and the temperature deviation has a great influence on the viscosity. The temperature increases and the viscosity decreases. Therefore, special attention should be paid to keep the temperature of the liquid to be measured constant around the specified temperature point, and it is best not to exceed 0.1 °C for accurate measurement. For this reason, our company specializes in the production of constant temperature cups and constant temperature tanks to be used together with DHJ series viscometers.
