Product overview
Guarded Hot Plate GHP 721-900 mm designed for research & development with customizable heating plates and upper-loading test chamber. Allows insertion of heavy or complex specimens without damaging measuring plates. Data acquisition and control via external Lambda Control desktop unit and PC with Windows and Lambda software. NETZSCH TAURUS Instruments GmbH focuses on thermal conductivity instruments for building and insulation materials.

Highlights

• Guarded Hot Plate method for absolute thermal characterization of insulation materials.
• Accommodates large specimens (900 mm x 900 mm chamber) and variable heating plate sizes.
• Upper-loading/swiveling chamber for safe insertion of heavy or bulky samples.
• Adapted for thick, high-density specimens and composite components.

Applications

• R&D and quality control for insulation, construction materials and insulating glass.
• Characterization of thick specimens, layered assemblies and large structural parts.
• Material selection and thermal performance testing in laboratories and production support.

Method
The Guarded Hot Plate method measures steady-state thermal conductivity (λ, W/(m·K)) by establishing a controlled temperature difference ΔT between a heated plate and cold plates across the specimen thickness. The guard ring is maintained at hot plate temperature to minimize lateral heat losses.

Standards

• ISO 8302, ASTM C177
• EN 1946-2, EN 12664, EN 12667
• DIN EN ISO 8497 (related guarded hot pipe methods)

Technical features and usability

• Upper specimen insertion to avoid damage to measuring plates.
• Motorized adjustment of upper plate and integrated thickness/pressure measurement.
• Networked control and data logging via Lambda software.
• Custom heating plate sizes and optional cooling systems.
