Introduction
This instrument is designed and manufactured for the low temperature performance test environmental conditions of petroleum products stipulated in SH/T0248 “Determination of cold filter point of distillate fuel”, GB/T6986 “Determination of petroleum cloud point”, GB/T3535 “Determination of pour point of Petroleum products”, GB/T510 “determination of freezing point of Petroleum products”.
Instrument structure and technical characteristics
1, the instrument is mainly composed of desktop box and flip bucket cold tank two parts, compact structure, reasonable layout, simple and convenient operation, and the use of environmental protection compressor, digital temperature controller, unique metal cold bath, good cooling effect, high temperature control accuracy, cold bath temperature uniform and stable.
2, the instrument is also equipped with manual button countdown, skip bucket automatic countdown and buzzer reminder function.
3. The freezing point, pour point and turbidity point test of petroleum products can be determined according to the method specified in the standard; Combined with LC-2, the cold filter point test of petroleum products can be realized.
