Freezing Point Tester AZA1322
The AZA1322 Freezing Point Tester from AZA Lab is a fully automated, high-precision instrument designed for determining the freezing point of aviation fuels in accordance with ASTM D7153. Utilizing the automatic laser detection method, the system accurately identifies the lowest temperature at which fuel remains free of solid hydrocarbon crystals.
Freezing point determination is critical for aviation safety, as fuel temperature decreases significantly with altitude, speed, and flight duration. The AZA1322 ensures that aviation fuels meet regulatory requirements by confirming that the freezing point remains below the minimum operational temperature, guaranteeing safe fuel flow and reliable aircraft performance.
Description
Operating Principle
The AZA1322 uses laser-based optical detection to continuously monitor crystal formation during controlled cooling. The exact freezing point is automatically detected and recorded with high accuracy, eliminating subjectivity and operator variability associated with manual methods.
