1.Technical parameters  

2.Performance characteristics

Cascade compressor for refrigeration; four baths and sixteen holes; temperature control points: 0, -17°C, -34°C, -51°C, (-68°C) 

3.Applicable standards

BF-12A pour point tester is in accordance with national standards GB/T3535 and the American Society for Testing

 and Materials Standard ASTM D97 to be designed and manufactured. This instrument applies to determine the pour  point of petroleum and petroleum products.   

4.Structural characteristics

 This instrument mainly consists of refrigeration system and temperature controlling system.  The refrigeration system is composed of fully closed double compressor assembly, including compressor, condenser, evaporation condenser, throttle capillary tube, and evaporator.

The instrument uses the digital temperature controller to control the temperature. The digital temperature controller can display the setting temperature and the actual temperature intuitively, so that it's easy to set and correct the temperatures.
