Guarded Heat Flow Meter
Published: 1/6/2025
The DRH300 conducts thermal conductivity and thermal resistance measurements using a dual heat flow meter method in compliance with standards such as ASTMC518, ISO8301, and GB/T10295. It is ideal for applications involving insulation materials, ceramics, rubber, and other related materials, providing full automation in testing, data processing, and reporting.
Product Description
The DRH300 represents a new standard for accurate, rapid, and user-friendly industrial measurement systems for the thermal performance of insulation materials. It automates functions from temperature control to data acquisition and analysis, ensuring consistent repeatability in tests. The instrument leverages over twenty years of designing expertise, providing robust performance with precise temperature control and dual heat flow sensor configuration.
The system quickly adapts to stable conditions, allowing rapid measurement of sample properties. Users can choose to terminate or extend measurement times, with some testing taking as little as five minutes, making it suitable for quality control and process management. Measurements are strictly standardized to ASTMC518, ISO8301, and GB/T10295, guaranteeing reliability.
Designed to test materials such as insulation plates, clay, sand, ceramics, and plastics, the DRH300 employs dual heat flow meters within a computerized system to automate reporting, data storage, and procedural operations, complemented by an optional embedded computer for touchscreen operation.
