Acid Number Tester LAAT-T2012

Introduction

Acid Number Tester is automated and controlled by microprocessor unit. It offers 0 to 1800.0 mV potential measurement range and ≥0.05 mg /g acid number measurement range. It works on potentiometric titration principle. Recording the titration of the electrode potential and the titration volume, find out the equivalence point and corresponding titrant volume, and thus obtained the sample pH value. This unit can accurately detect the acid value of transformer oil, turbine oil, anti-oil, diesel, gasoline and other petroleum products. It offers Standard Determination of acid number, Determination of acid number in transformer and turbine oils in service (), ).

FAQs

1. What kind of titration curve does the Acid Number Tester display?

It Acid Number Tester provides a real-time E–V (potential vs. volume) titration curve. This helps users visually confirm the progression and endpoint of the titration process. The curve is automatically stored and can be printed or exported for reports. This graphical insight adds confidence and traceability to the results.

2. Does the Acid Number Tester support multi-sample testing setups?

The Acid Number Tester is optimized for single-sample precision, its quick operation and automated cleaning make it efficient for sequential sample testing. It’s compatible with lab workflows that require analysis of multiple oil samples throughout the day. Users can run successive tests with minimal downtime. This supports higher productivity in routine testing environments.

3. How does the Acid Number Tester help in troubleshooting or error handling?

Acid Number Tester includes built-in diagnostic functions that monitor electrode performance, titrant levels, and hardware status. If an error occurs, the system provides specific prompts or codes to guide the operator through corrective steps. This reduces downtime and prevents inaccurate results. It also records system alerts in the log for audit tracking.

4. Is the Acid Number Tester adaptable to future upgrades or changes in workflow?

It Acid Number Tester is designed with modular components and firmware support, making it easy to upgrade as lab needs evolve. It can accommodate different electrode types or burette sizes if workflows demand it. The RS232 port and Windows-compatible software allow it to integrate into broader lab automation systems. This ensures the instrument stays relevant even as testing standards or methods evolve.

5. How does the Acid Number Tester enhance safety during chemical analysis?

The Acid Number Tester enhances safety through automatic reagent handling, enclosed titration components, and minimal manual interaction with acids or solvents. Built-in prompts guide safe operation and maintenance. The enclosed electrode and burette system also reduce the risk of spills or vapor exposure. These features support safer handling of hazardous substances during acid number testing.
