Rotary Viscometer
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.

Notes
1. The thermostatic bath should be placed on a solid workbench;
2. No vibration, no harmful gas;
3. The room temperature should be relatively stable, not high or low, otherwise it will affect the temperature control accuracy; the room temperature should be around 25℃, (especially -40℃, -65℃, -80℃ thermostat) It will affect the heat dissipation of the compressor, reduce the cooling efficiency, and easily cause failure;
4. The constant temperature bath should be maintained regularly, especially if the cooling speed is slowed down after working for a period of time, the plastic mesh plate of the constant temperature bath should be removed, and the dust of the compressor and heat sink should be removed.
