Product Description
The DRX-II-300A uses a guarded hot plate configuration for solid insulation and construction-material specimens. It references GB/T 10294-2008 and ISO 8302. Computer software provides temperature measurement, data acquisition, calculation, and report output.
The configuration can provide online specimen-thickness measurement, specimen-pressure monitoring and adjustment, temperature compensation, and cooling by thermoelectric, compressed-air, water, or ethanol-based refrigeration.
