Introduction
An aniline point tester is an instrument used to measure the aniline point of the petroleum products, which indicates the aromatic content and the solvency, and it is used in the petroleum, the fuel, and the quality control industries. The aniline point is the lowest temperature at which the sample is completely miscible with an equal volume of the aniline, and it is measured by the mixing of the sample with the aniline and the heating or the cooling until the mixture becomes clear, following the standard test methods, such as the ASTM D611; the aniline point tester consists of a test tube, a heating and a cooling system, a temperature measurement system, and the observation, and it provides the aniline point, with the temperature controlled; the aniline point tester is used for the measurement of the aniline point of the fuels, the solvents, and the other petroleum products, for the assessment of the aromatic content, for the quality control, for the classification, and for many other applications, and it is an essential instrument for the petroleum testing. 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, aniline point testers are essential for the solvency assessment.

FAQ
Q1: What testing scenarios is this tester mainly applied to?
A: The aniline point tester is used in petroleum refineries, fuel quality laboratories, solvent manufacturing, lubricant production and research institutions to measure the aniline point of petroleum products, hydrocarbons and solvents. The aniline point is the minimum temperature at which equal volumes of aniline and the sample are miscible, providing an indication of the aromatic content and solvency characteristics of the material. It supports characterization of gasoline, diesel, jet fuel, solvents, lubricating oils and hydrocarbon mixtures, evaluation of solvent power for rubber and polymer applications, refinery process control, and product specification compliance. It is essential for petroleum and solvent laboratories requiring a simple, standardized method to assess aromatic content and solvency properties for product formulation, quality control and process optimization in refining, solvent production and lubricant manufacturing where aniline point correlates with hydrocarbon composition and application performance.
Q2: What standards does the tester comply with?
A: The test method follows ASTM D611 for aniline point and mixed aniline point of petroleum products and hydrocarbon solvents, ISO 2977 for petroleum products aniline point, and the corresponding GB/T methods. The instrument complies with relevant laboratory safety standards. Temperature accuracy should be verified with certified reference materials.
Q3: What is the warranty period for the whole machine and key components?
A: The whole tester is covered by a 12-month warranty. The heating/cooling system, temperature sensor and controller are covered, while test tubes and aniline reagent are consumables. Damage from improper use or unauthorized repair is excluded.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires trained laboratory personnel familiar with petroleum testing and aniline point procedure. We provide an operation manual and remote guidance. Proper sample preparation, aniline handling, temperature control and phase separation observation are important for accurate results. Aniline is toxic and requires proper safety handling.
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. Test tube cleanliness verified before each use. Full method verification with a reference sample recommended periodically for accredited laboratories. Heating/cooling rate verified per the standard method.
Q7: Are supporting consumables universal?
A: Aniline reagent, test tubes and accessories are available from chemical and laboratory suppliers. Long-term consumable cost is low, with aniline reagent being the main recurring item.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes automation level, temperature range, sample capacity and detection method. Additional test tubes 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 tester 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 measures aniline point of petroleum products and hydrocarbon solvents within the method range. Samples that are not completely miscible with aniline may require mixed aniline point testing. Very dark or viscous samples may affect visual phase separation detection. Users should follow proper aniline safety handling procedures (aniline is toxic and absorbed through skin), ensure clean, dry test tubes, control heating/cooling rate per the standard, and use appropriate personal protective equipment. The test should be performed in a fume hood due to aniline toxicity and volatility.
