Introduction
A petroleum aniline point tester is an instrument used to measure the aniline point of the petroleum products, which is the lowest temperature at which the sample is completely miscible with the equal volume of the aniline, and it is used in the petroleum, the fuel, and the quality control industries. The aniline point indicates the aromatic content of the oil, and the higher aniline point indicates the lower aromatic content, and the petroleum aniline point tester measures the aniline point by the mixing of the sample with the aniline, the heating, and the observation of the miscibility, following the standard test methods, such as the ASTM standards; the petroleum aniline point tester consists of a test tube, a heating system, a temperature control and a measurement system, and the observation, and it provides the aniline point, with features such as the digital temperature display; the petroleum aniline point tester is used for the measurement of the aniline point of the fuels, the solvents, and the lubricants, for the assessment of the aromatic content, for the quality control, for the blending, and for many other applications, and it is an essential instrument for the petroleum testing. Petroleum aniline 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 aniline point measurement, petroleum aniline point testers are essential for the product characterization.

FAQ
Q1: What testing scenarios is this instrument mainly applied to?
A: The petroleum aniline point tester is used in petroleum refineries, solvent manufacturing, lubricant laboratories and third-party testing organizations to determine the aniline point of diesel fuel, lubricating oils, hydrocarbon solvents and other petroleum products. It supports product specification compliance, aromatic content estimation, solvency evaluation, diesel fuel quality assessment and solvent classification. The aniline point is the minimum temperature at which equal volumes of aniline and the sample are miscible, providing an indirect measure of aromatic hydrocarbon content. Lower aniline point indicates higher aromatic content and greater solvency, which affects diesel ignition quality, rubber compatibility, paint thinning performance and environmental impact. It is a standard test for characterizing hydrocarbon composition and evaluating solvent power in industrial and automotive applications.
Q2: What standards does the instrument comply with?
A: The test method follows ASTM D611 for aniline point and mixed aniline point, ISO 2977 for petroleum products aniline point, and the corresponding GB/T 262 method. The instrument complies with relevant laboratory electrical and chemical safety standards. Test tube dimensions and heating rate should follow the standard specification.
Q3: What is the warranty period for the whole machine and key components?
A: The heating apparatus and controller are covered by a 12-month warranty. Test tubes, thermometers and seals are consumables excluded from warranty. Damage from improper heating rate, aniline spillage 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 aniline handling safety. We provide an operation manual and remote guidance. Proper sample-aniline ratio, mixing technique, heating rate control and cloud point observation are critical for accurate aniline point determination. Aniline is toxic and should be handled in a fume hood with appropriate personal protective equipment.
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: Temperature calibration against a reference thermometer is recommended every 6-12 months. Heating rate verification should be performed periodically. Full method verification with a certified reference material is recommended for accredited laboratories.
Q7: Are supporting consumables universal?
A: Test tubes, thermometers and aniline reagent are available from laboratory suppliers, though tube dimensions should match the standard method. Aniline should be of appropriate purity per the method. Long-term consumable cost is low to moderate.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes automation level, temperature range 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 apparatus, 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 petroleum products and hydrocarbon solvents within the method aniline point range. Samples should be dry and free of contamination. Highly aromatic samples may have very low aniline points requiring low-temperature bath capability. Users should follow proper aniline safety procedures, including use in a fume hood and proper disposal of aniline waste. The mixed aniline point method may be used for samples with very low aniline points that are difficult to measure directly.
