Automatic Open and Closed Cell Content Analyzer True Density and Porosity Tester

Product Overview

This advanced gas displacement analyzer provides rapid, non-destructive characterization of open cell ratio, closed cell ratio, cut-surface corrected cell content, true density, and total porosity. Utilizing precision gas pycnometry based on Archimedes' principle and Boyle’s Law, the system employs inert gas expansion to accurately measure skeletal and true volumes of complex solid structures without altering sample integrity or risking dissolution errors inherent to liquid submersion methods.

Engineered specifically for quality control and research environments, the equipment is widely adopted across thermal insulation manufacturing, acoustic material development, aerospace composite fabrication, geological core analysis, and powder metallurgy. It accommodates diverse sample morphologies, including rigid polyurethane and phenolic foams, porous ceramics, sintered metallic components, soils, and non-volatile slurries or liquids.

Designed for rigorous industrial duty cycles, the instrument integrates an all-metal manifold piping architecture with pneumatic control valves and high-precision silicon diaphragm pressure transducers. This robust build eliminates thermal drift, prevents internal gas leakage, and ensures long-term operational repeatability and accuracy across demanding multi-shift laboratory workflows.

Key Features

• Integrated All-Metal Manifold System: Houses all critical flow channels within a solid, joint-free metal manifold block, eliminating external tube connections to minimize potential leak points and maintain a highly uniform internal thermal field.
• Zero-Heat Pneumatic Valve Technology: Utilizes high-durability pneumatic actuation valves instead of conventional solenoid valves, completely eliminating localized electromagnetic heat generation and preventing temperature-induced measurement drift.
• Automated Sample Cell Clamping: Features an automated pneumatic loading mechanism that docks the sample chamber into position with standardized seating force, preventing operator-induced variance and ensuring hermetic sealing.
• Optimized Chamber Volumetric Efficiency: Accommodates precision-machined sample holders tailored directly to standardized specimen geometries, maximizing chamber fill factor to enhance displacement resolution and testing sensitivity.
• High-Precision Silicon Diaphragm Transducer: Employs a capacitance-based silicon diaphragm pressure sensor delivering accuracy within 0.1% of actual reading across the entire 0 kPa to 100 kPa operational envelope.
• Programmable Pressure De-escalation: Allows operators to customize target test pressures below atmospheric thresholds, preventing cellular wall rupture or structural deformation in ultra-low-density elastic or fragile rigid foams.
• Dual Operating Architecture: Equipped with an internal Windows industrial computer for standalone touchscreen operation, alongside serial communication capabilities for external PC control with synchronized voice-guided prompts.
• Automated Manifold Integrity Diagnostics: Automatically conducts continuous baseline volume verification and pressure decay leak checks on reference and sample chambers prior to analysis runs.
• Automatic Atmospheric Depressurization: Automatically vents and balances the test chamber to local atmospheric pressure upon analysis completion, eliminating sample blowout or particulate scatter during removal.
