The NETZSCH PCE 428 test bench has a mechanical lever, which positions the base plate for the sample and reference cones in the hood furnace from below; a viewing window in the furnace lid with a radiation filter and surface mirror allow visual determination of the pyrometric cone equivalent. The maximum temperature for this melting point determination is 1700°C (complies with SK 31, ISO 170), in accordance with DIN EN 993-12. The furnace is equipped with a single temperature controller.
The NETZSCH PCE 428 is operated independent of software.
