GD-3609 Naphthaline Crystillazition Point Tester

GD-3609 Naphthaline Crystillazition Point Tester is suitable to determine the crystallizing point of refined naphthalene. Purpose:GD-3609 Naphthaline Crystillazition Point Tester  is designed and made as per the National Standard of Peoples 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. Main technical specification and parameters    1. Power supply: AC 220 V±10%, 50 Hz    2. Heating device: by electricity; power is 600 W.    3. Stirring motor:         (1) Power: 6 W         (2) Rotation speed: 1200 r/min    4. Temperature controlling range: room temperature100    5. Temperature controlling accuracy: ±1    6. Ambient temperature: room temperature35    7. Relative humidity: ≤85%
