Purpose:
The instrument is designed and made as per requirements for constant temperature water bath stipulated in the National Standard GB/T510 "Test Methods for Solidifying Point of Petroleum Products". It is used for sample treatment in the range of room temperature to 60 °C.

Technical characteristics:
1. It uses a two layers cylinder, and electric stirrer, so it can keep temperature stable at controlling temperature.
2. It adopts a digital temperature controller, so it is convenient to set temperature with high temperature controlling accuracy.
3. You can put 7 pieces of solidifying point test tubes and 2 pieces of cold filter plugging point test tubes in the bath, so it can keep temperature of 9 pieces of samples constant at a time.
4. Table structure, newly designed, and it is convenient to be operated.
