Introduction
A petroleum freezing point tester is an instrument used to measure the freezing point of the petroleum products, such as the jet fuels and the diesel fuels, which is the temperature at which the crystals begin to form in the fuel, and it is used in the petroleum, the fuel, and the quality control industries. The freezing point indicates the lowest temperature at which the fuel can be used, and it is measured by the cooling of the sample at a controlled rate and the observation of the formation of the crystals, following the standard test methods, such as the ASTM standards; the petroleum freezing point tester consists of a cooling system, a test vessel, a temperature control and a measurement system, a stirrer or the observation, and the controls, and it provides the freezing point, with features such as the digital temperature display; the petroleum freezing point tester is used for the measurement of the freezing point of the jet fuels, the diesel fuels, and the other petroleum products, for the quality control, for the assessment of the low-temperature properties, for the compliance with the specifications, and for many other applications, and it is an essential instrument for the fuel testing. Petroleum freezing point testers are used in the petroleum industry, in the fuel industry, in the laboratories, in the quality control, and for many other applications. With their freezing point measurement, petroleum freezing point testers are essential for the low-temperature fuel testing.

FAQ
Q1: What testing scenarios is this instrument mainly applied to?
A: The petroleum freezing point tester is used in petroleum refineries, aviation fuel laboratories and third-party testing organizations to measure the freezing point of aviation turbine fuel (jet fuel) and other petroleum products. It supports jet fuel specification compliance, refinery process control, product certification and aviation safety assurance. Freezing point is the temperature at which hydrocarbon wax crystals form and disappear upon cooling and heating, indicating the lowest temperature at which the fuel remains pumpable and free of solid crystals that could block fuel filters at altitude. It is a critical safety parameter for aviation fuel, ensuring that the fuel remains liquid and flowable under the low temperatures encountered during high-altitude flight.
Q2: What standards does the instrument comply with?
A: The test method follows ASTM D2386 for freezing point of aviation turbine fuels, ISO 3013 for aviation turbine fuels freezing point, and the corresponding GB/T 2430 method. The instrument complies with relevant laboratory electrical safety standards. Test tube dimensions and cooling rate should follow the standard specification.
Q3: What is the warranty period for the whole machine and key components?
A: The cooling bath and controller are covered by a 12-month warranty. Test tubes, thermometers and seals are consumables excluded from warranty. Damage from improper coolant use, overcooling or unauthorized repair is excluded.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires trained laboratory personnel familiar with the test method and low-temperature technique. We provide an operation manual and remote guidance. Proper sample preparation, cooling rate control and crystal observation are critical for accurate freezing point determination.
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: Bath temperature calibration against a reference thermometer is recommended every 6-12 months. Cooling rate verification should be performed periodically. Full method verification with a certified jet fuel reference sample is recommended for accredited laboratories.
Q7: Are supporting consumables universal?
A: Test tubes, thermometers and coolant are available from laboratory suppliers, though tube dimensions should match the standard method. Long-term consumable cost is low to moderate depending on coolant type.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes minimum temperature, bath capacity and number of test positions. Additional test tube sets and accessories can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: Standard delivery includes the bath, test tubes and accessories with an operation manual. Remote commissioning guidance is provided. On-site service is not included for standard orders.
Q10: What types of samples are compatible with this equipment?
A: The tester handles aviation turbine fuels and other petroleum products within the method freezing point range. Samples should be clear and free of water and particulate contamination. Highly paraffinic fuels may form crystals at higher temperatures. Users should follow the standard method for sample handling, cooling rate and crystal observation, including proper illumination for detecting the disappearance of wax crystals during warming.
