תיאור
The GHP 456 Titan® is the ideal tool for researchers and scientists in the field of insulation testing. Based on the well-known, standardized guarded hot plate technique (e.g. ISO 8302, ASTM C177, DIN EN 12939 or DIN EN 12667), the system features unrivalled performance over an unmatched temperature range.
Combining state-of-the-art technology with the highest quality standards, NETZSCH has designed a robust and easy-to-operate instrument, featuring unparalleled reliability and optimum accuracy over a broad temperature range.
The NETZSCH GHP 456 Titan® is the new benchmark in Guarded Hot Plate measurements.

Accessories
-
Various pump systems (rotary pumps, turbo molecular pumps) are available for the GHP 456 Titan®.The system can be easily extended later on by add the appropriate pump to the connections of the system.
- Standard materials: Various kinds of certified (NIST, NPL) standard materials (fiber insulations, foam insulations) are available for the system.
- Cooling of the heat sinks: The heat sinks can be cooled with forced air (for mean sample temperatures above 40°C) with a chiller (for mean sample temperatures above 0°C) or with liquid nitrogen. The liquid nitrogen is supplied from a feeding system via a software controlled supply system.
- For measurements of powders and flakes special calcium silicate frames are available, fitting exactly to the plate dimensions.
