Petroleum Tan And Tbn Tester

Introduction

A petroleum TAN and TBN tester is an instrument used to measure the total acid number (TAN) and the total base number (TBN) of the petroleum products, such as the lubricating oils and the fuels, and it is used in the petroleum, the lubricant, and the quality control industries. The TAN indicates the acidic components in the oil, which are formed by the oxidation and the contamination, and the TBN indicates the alkaline reserve of the oil, which neutralizes the acidic products of the combustion, and the petroleum TAN and TBN tester measures these parameters by the potentiometric or the colorimetric titration, following the standard test methods, such as the ASTM standards; the petroleum TAN and TBN tester consists of a titration system with the burette or the syringe, a sample vessel, a detection system, and a control and a data system, and it provides the TAN and the TBN values, expressed in milligrams of the potassium hydroxide per gram, with features such as the automated titration; the petroleum TAN and TBN tester is used for the measurement of the TAN and the TBN of the lubricating oils, for the monitoring of the oil condition, for the assessment of the oil life, for the quality control, and for many other applications, and it is an essential instrument for the oil testing. Petroleum TAN and TBN testers are used in the petroleum industry, in the lubricant industry, in the laboratories, in the maintenance, and for many other applications. With their titration, petroleum TAN and TBN testers are essential for the oil condition monitoring.

FAQ

Q1: What testing scenarios is this instrument mainly applied to?

A: The petroleum TAN and TBN tester is used in lubricant manufacturing, used oil analysis laboratories, transformer maintenance facilities and petroleum research institutions to measure the total acid number and total base number of lubricating oils, used engine oils, transformer oils and additive packages. It supports oil formulation evaluation, in-service oil condition monitoring, remaining useful life assessment, transformer oil degradation evaluation and product specification compliance. TAN indicates acidic constituents from oil oxidation, while TBN measures alkaline reserve for neutralizing acids in engine oils. Together they provide critical information about oil degradation, corrosion risk and remaining service life, supporting condition-based maintenance and oil change interval optimization for engines, turbines and industrial machinery.

Q2: What standards does the instrument comply with?

A: TAN measurement follows ASTM D664 and ISO 6618; TBN follows ASTM D2896 and ISO 3771. Corresponding GB/T 7304 and GB/T 264 methods apply. 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 TAN and TBN 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 certified TAN and TBN reference oils 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 TAN and TBN ranges. Highly viscous or solid samples may require heating and solvent dissolution. Used oils with high sediment content should be filtered or homogenized before analysis. Samples containing strong acids, bases or particulates may interfere with titration. Users should follow the standard method for sample preparation, solvent selection and electrode maintenance, and select the appropriate TAN or TBN method based on expected value and oil type.
