Naphthalene Crystallizing Point Tester

Purpose:
The instrument is designed and made as per the National Standard of People’s Republic of China –GB 3069.2 “Test Methods for Naphthalene Crystallizing Point”. It is suitable to determine the crystallizing point of refined naphthalene and industrial naphthalene, which are made by washing, distilling and extracting the naphthalene distillate. The naphthalene distillate is from the distillation of coal tar at a high temperature.
Main characteristics:
1. It can control the test temperature of the water bath and display the temperature on the LCD.
2. It can stir the test sample by a electromagnetic device. The stirring frequency can be set continuously.
3. Adopt double tubes working mode, so it can do tests for two samples at the same time.
