Automatic TAN Total Acid Number Titrator
Automatic TAN Total Acid Number Titrator
MT-T200
The Automatic TAN Total Acid Number Titrator is designed for accurate determination of Total Acid Number (TAN) and Total Base Number (TBN) in petroleum products, lubricants, and oils using potentiometric titration.
Introduction
Total Acid Number represents the amount of alkaline reagent required to neutralize acidic components present in an oil sample, while Total Base Number indicates the alkaline reserve available to neutralize acidic contaminants generated during oil oxidation and degradation.
This Total Acid Number Titrator performs high-precision potentiometric titration in non-aqueous media and automatically determines the titration endpoint using a pH electrode system. The entire analysis procedure including titration control, endpoint detection, calculation, and result output is performed automatically.
This system complies with major international oil analysis standards such as ASTM D664, ASTM D2896, ASTM D4739, ISO 3771, and IEC 62021, making it suitable for professional laboratories performing oil condition monitoring and lubricant quality analysis.
Typical Applications
The Automatic Total Acid Number Titrator is widely used for oil quality monitoring and analysis of:
- Transformer insulating oil
- Lubricating oils and industrial lubricants
- Mineral oils and petroleum products
- Natural and synthetic fats
- Food oils and edible fats
Typical application environments include:
- Oil analysis laboratories
- Power generation and electrical utilities
- Petroleum refining laboratories
- Lubricant manufacturers
- Research and quality control laboratories
Key Features
1. Potentiometric Titration with High Precision pH Detection
The system performs potentiometric titration using high-precision pH electrodes and advanced control algorithms to determine titration endpoints accurately in non-aqueous environments.
2. Automatic TAN and TBN Determination
The instrument supports standardized methods for both acid number and base number analysis, allowing laboratories to evaluate oil oxidation and additive depletion in a single system.
3. Intelligent Titration Control Algorithm
The titration speed is dynamically adjusted according to the reaction rate to ensure accurate endpoint detection while minimizing analysis time.
4. Built-In Precision Burette System
The integrated burette is enclosed inside the instrument and visible through a safety window, minimizing chemical exposure and improving operational safety. Optional burette volumes: 1mL, 5mL, 10mL, 25mL.
5. Flexible Multi-Sample Automation
The titration system can operate with an independent titration stand or an optional 16-position autosampler, enabling fully automated batch analysis without manual supervision.
6. Cloud Data Storage Capability
With built-in Ethernet connectivity, test data can be uploaded to cloud servers, supporting remote monitoring and laboratory data management.
7. Intelligent Method Presets
Pre-configured titration methods allow operators to start measurements immediately without complex parameter configuration.
