Labtron Acid and Alkali Tester is specialized to measure pH levels of solutions, determining whether they are acidic, neutral, or alkaline. They can detect even slight variations, showcasing high sensitivity. Their calibration processes are straightforward, allowing for consistent and reliable result over time. They are compatible with various probes, enhancing their usability. Our Acid and Alkali Tester is applicable in agriculture, water quality testing, food production, pharmaceuticals, and environmental monitoring.






The Acid Number and Acidity Tester LAAT-A11 is engineered for reliable and repeatable acid number testing in fuels like diesel, gasoline, and kerosene. Its automated titration system reduces manual errors, while adjustable heating ensures test consistency across different sample types. The instrument follows ASTM D664 standards, which are widely accepted in the petroleum industry. These features make it ideal for both quality control and research environments.
Our Acid Number and Acidity Tester LAAT-A11 is a fully automatic device, including titrant delivery and endpoint recognition. It reduces the need for manual operation, which helps save time and increases workflow efficiency. The automatic process also limits human error, especially in endpoint judgment. Its automation makes it well-suited for high-throughput lab environments.
Labtron’s Acid Number and Acidity Tester LAAT-A11 is designed with enclosed systems to minimize exposure to reagents. The adjustable heating system prevents overheating, and the materials are selected for chemical resistance. Proper grounding and standard voltage operation ensure electrical safety. Users are also advised to follow standard lab practices for handling fuels and acids.
The Acid Number and Acidity Tester LAAT-A11 features automation and simplified operation, making it ideal for laboratories with moderate to high testing volumes. It shortens test durations, reduces the risk of user error, and ensures faster turnaround. Its robust design and streamlined workflow support consistent performance under frequent use. This enhances overall throughput without sacrificing accuracy.
The Acid Number and Acidity Tester LAAT-A11 uses a potentiometric electrode system to detect the endpoint of titration accurately. This method is ideal for petroleum samples because it’s unaffected by sample color or turbidity. Unlike visual indicators, the electrode system provides consistent results even with dark fuels or oils. It ensures precision, especially when detecting very low acid levels.
