Introduction
A petroleum automatic oil acidity tester is an instrument used to measure the acidity of the petroleum products, such as the lubricating oils, the fuels, and the transformer oils, and it is used in the petroleum, the lubricant, the power, and the quality control industries. The acidity is measured by the titration of the sample with the alkaline reagent, and the acid number indicates the amount of the acidic components, such as the organic acids, which are formed by the oxidation and the contamination, and the petroleum automatic oil acidity tester performs the titration automatically, following the standard test methods, such as the ASTM standards, and it provides the acid number, expressed in milligrams of the potassium hydroxide per gram; the petroleum automatic oil acidity tester consists of a titration system with the burette or the syringe, a sample vessel, a detection system, such as the potentiometric or the colorimetric detection, and a control and a data system, and it provides features such as the automated titration and the data management; the petroleum automatic oil acidity tester is used for the measurement of the acidity of the lubricating oils, for the monitoring of the oil condition, for the assessment of the oxidation, for the quality control, and for many other applications, and it is an essential instrument for the oil testing. Petroleum automatic oil acidity testers are used in the petroleum industry, in the lubricant industry, in the power industry, in the laboratories, and for many other applications. With their automatic titration, petroleum automatic oil acidity testers are essential for the oil condition monitoring.

FAQ
Q1: What testing scenarios is this instrument mainly applied to?
A: The petroleum automatic oil acidity tester is used in petroleum refineries, lubricant laboratories, transformer maintenance facilities and third-party testing organizations to measure the acidity or acid number of lubricating oils, transformer oils, diesel fuels and other petroleum products. It supports oil quality assessment, used oil condition monitoring, transformer oil degradation evaluation and product specification compliance. Acid number indicates the amount of acidic constituents in oil, which increases with oxidation during service and can cause corrosion, sludge formation and reduced lubricating performance. Automatic titration improves accuracy and throughput compared with manual color-indicator methods.
Q2: What standards does the instrument comply with?
A: The test method follows ASTM D664 for acid number by potentiometric titration, ISO 6618 for petroleum products acidity, and the corresponding GB/T 7304 and GB/T 264 methods. The instrument hardware complies with relevant laboratory electrical safety standards. Electrode calibration should use certified buffer solutions.
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 titration unit, electrode, heating system and controller are covered, while reagents, electrode filling solution and tubing are consumables excluded from warranty. Electrode damage from improper storage or drying is also excluded.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires trained laboratory personnel familiar with titration technique and oil sample handling. We provide an operation manual and remote guidance. Proper sample dissolution, electrode maintenance and calibration are important for accurate and repeatable results.
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: The pH electrode should be calibrated with standard buffer solutions before each analytical batch and after electrode replacement. Full system verification with a certified acid number reference oil is recommended every 6-12 months. Electrode slope should be monitored as a performance indicator.
Q7: Are supporting consumables universal?
A: Titration reagents, solvents and buffer solutions are available from chemical suppliers, though original reagents are recommended for consistent performance. The electrode is a specific model and should be sourced from the manufacturer or authorized distributor.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes titration range, electrode type and sample handling configuration. Additional accessories such as spare electrodes, titration vessels and reagent sets 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 instrument, electrode and accessories with an operation manual. Remote commissioning guidance is provided. On-site installation and training are not included for standard orders but can be arranged for laboratory setup projects.
Q10: What types of samples are compatible with this equipment?
A: The tester handles petroleum oils and products within the method acid number range. Highly viscous or solid samples may require heating and solvent dissolution. Samples containing strong acids, bases or particulates may interfere with titration and require special pretreatment. Used oils with high sediment content should be filtered or homogenized before analysis. Users should follow the standard method for sample preparation and solvent selection.
