DENSITY METER AZA0969
The AZA0969 Digital Density Meter from AZA Lab is a high-precision analytical instrument designed for the accurate determination of density, relative density, and API gravity of liquids, petroleum products, and crude oils. The instrument is manufactured in accordance with ASTM D4052 and ASTM D5002, utilizing advanced digital oscillating U-tube technology to deliver fast, repeatable, and highly reliable results.
Density is a critical physical property for characterizing petroleum fractions, fuels, chemicals, and process fluids. The AZA0969 provides exceptional accuracy across a wide measuring range, making it an ideal solution for petroleum laboratories, refineries, inspection agencies, chemical plants, and quality control laboratories.
Description
Principle of Operation
The AZA0969 operates on the digital density analyzer principle, where the oscillation frequency of a precision glass U-tube changes as a function of the sample’s density. The system automatically injects the sample, stabilizes the temperature, and measures density with minimal operator intervention.
Integrated HD video monitoring allows real-time observation of the sample inside the measuring cell, reducing errors caused by air bubbles, contamination, or incomplete filling. The measured density values can be automatically converted to API gravity, relative density, or alcohol concentration using built-in calculation models or user-defined formulas.

The AZA0969 Density Meter is designed to meet or exceed the requirements of:
-
ASTM D4052 – Density, Relative Density, and API Gravity of Liquids by Digital Density Meter
-
ASTM D5002 – Density and Relative Density of Crude Oils by Digital Density Analyzer
