DRX-II-300A Guarded Hot Plate Analyzer

DRX-II-300A is a guarded hot plate analyzer that measures the thermal conductivity of solid insulation and construction materials by the guarded hot plate method. It is configured for board, fiber, foam, composite-panel, rubber, cement, powder, filler, and gypsum-board specimens, with a hot-plate setpoint from room temperature to 110 °C.

Product Description

The guarded hot plate arrangement is intended for fiberboard, loose-fill glass fiber, ceramic fiber, XPS/EPS/PUR foams, composite and vacuum panels, rubber, cement products, powders, fillers, and gypsum board. Referenced standards are GB/T 10294-2008 and ISO 8302.

Configurable online thickness measurement and specimen loading-pressure measurement, display, and control are available. The dual-plate system provides thermal guarding, three-stage temperature protection, automatic parallel adjustment between the specimen and hot/cold plates, guard- and hot-plate temperature tracking, and specimen-thickness and mean-temperature compensation.

Computer interfacing supports real-time measurement and control, data analysis, storage, and report output. Cold-side cooling choices include thermoelectric cooling, compressed-air cooling, cooling water, and an ethanol-based refrigeration loop; horizontal and vertical configurations and an optional powder-test enclosure are available.

Ordering information: This page is a configuration overview. Specify the specimen dimensions and thickness, cold-side temperature range and cooling system, pressure-measurement option, electrical supply, instrument orientation, powder-testing configuration, and current software support when requesting a verified model-specific datasheet and quotation.
