The new 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 C 177 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 GHP 456 Titan® works with sheeted individually calibrated PT100 resistance temperature sensors (resolution 1 mK, accuracy in the range of a few 10 mK). Due to special sheeting, the sensors can be used up to 700°C (+ more than 100 K safety range).
The NETZSCH GHP 456 Titan® is the new benchmark in Guarded Hot Plate measurements.

TCT 426 - Thermal Conductivity Tester: furnace/hot-wire method
The TCT 426 works according to the hot wire method and is especially designed for the investigation of refractory rock. The measuring cross, parallel wire, and T(R) methods can be used in the instrument. The TCT 426 is indispensable for the efficient use of energy in industrial kiln engineering with refractories.
The hot-wire method is an absolute method for direct determination of the thermal conductivity, based on the measurement of the temperature increase of a linear heat source/hot wire (cross-wire technique) or at a specific distance from a linear heat source (parallel-wire technique).
The hot wire and thermocouple are embedded between two test pieces, which make up the actual test assembly. The time-dependent temperature increase after the heating current is switched on is a measure of the thermal conductivity of the material being tested.
Another variation, the so-called "Platinum Resistance Thermometer Technique" or "T(R) Technique", is described in ASTM-C 1113. Here an integral temperature measurement is carried out over the entire length of the hot wire; i.e. the hot wire is both heat source and temperature sensor at the same time.
The TCT 426 thermal conductivity tester enables the use of all three of the methods described in easily interchangeable, pre-wired measuring frames.
