I. Summary
The instrument is designed and made as per standards GB/T3535 Test Method for Pour Point of Petroleum Oils andSH/T0248 Diesel and domestic heating fuels- Determinaiton of cold filter plugging point. It is suitable to determine solidifying point and cold filter plugging point of petroleum products.
II. Main technical features
1. The material of workbench is stainless steel. It is composed of cold trough I and cold trough II. Threr are two cold baths in each trough. The cold baths are equal in temperature.
2. It is no need to use coolant in the cold chamber. The coolig rate is fast and efficiency is high. Temperature controller I and controller II control the temperature of chamber I and chamber II separately. The temperature in cold chamber II can reach -70℃.The accuracy can reach ±1℃.
3. The instrument adopts desk type structure. The design is simple and easy to use. The filter for cold filter plugging point is provided. Operator can do both solidifying point test and cold filter plugging point test after buying this instrument.
