True Density Fully Automatic Analyzer ZDM350

Fully Automatic True/Apparent Density Testerzdmdy350

Product Overview

The fully automatic density analyzer, developed and manufactured independently by our company, complies with the GB/T23561.2-2009 standard "Method for Determination of True Density of Coal and Rock - Gas Expansion Method for True Density Analysis." This intelligent analytical instrument utilizes the gas expansion displacement principle and is computer-controlled to automatically measure fundamental data such as true density, apparent density, and porosity of samples. Its advanced testing method makes it applicable in a wider range of fields compared to similar instruments, making it an essential analytical tool for modern mining units and testing institutions at all levels.

Performance Features

One-click start for fully automatic operation; software simultaneously calculates parameters such as true density, apparent density, and porosity; functions include printing, storing, querying experimental reports, setting permissions, and providing help.

Completes the entire testing process in 1-2 minutes, with a testing accuracy better than ±0.02%, repeatability better than ±0.015%, and resolution of 0.0001 g/ml.

Wide applicability, suitable for samples of various volumes above 0.01 ml; measurable parameters: true density, apparent density, porosity, skeletal volume, and apparent volume.

Modular gas path structure with no pipeline connections between valves, reducing leakage points; uniform temperature field and overall air tightness superior to similar products.

Uses 8 liters of high-purity inert helium gas with purity ≥99.99%; avoids adsorption interference from other gases affecting experimental results.
