TP-238 trace rapid freezing point tester is designed and manufactured on the basis of SH/T 0770, ASTM D5972 standard, the accuracy and repeatability of experimental results are consistent with requirements of ASTM D2386, GB/T2430 standard . The jet fuel sample is cooled automatically until solid crystallization occurs, then the temperature is recorded as the freezing point by controlling the temperature rise and recording the complete remelting of this solid crystallization into a liquid phase.
2. the working condition of the instrument: environmental temperature 10 ~ 35ºC, humidity ≤85%, working power supply AC220V±10%, 50Hz.
Structure characteristics 1.The instrument has a built-in testing room, which manages Microprocessor controlling.The testing room can cool and heat the sample, and observe the formation and disappearance of solid hydrocarbon crystals in the sample by optical means, then record the sample temperature. 2. 10.4 inches touch type LCD, built-in computer, Chinese display with real-time data and curve. Can store more than 10,000 experimental results, experimentalanalysis results are displayed on images. 3.The sample does not need to be processed in advance, and they can be put in the instrument directly to do the experiment. 4.Built-in cold source, no need of external cold source. Unique compressor refrigeration technology, cooling depth can reach -100ºC. 5. With efficient and fast database function, users can easily refer to and use the saved experimental results. 6. Password safeguards operation permission, ensuring database security. 7. International famous brands are selected for key components to ensure the performance and reliability of the instrument. 8.The instrument can be connected to the laboratory LIMS system and operate multi-machine networking.
