Insulation materials are growing in significance in a number of applications, including the insulation of buildings. Improved insulation reduces energy use and consequently heating costs for each individual household or industrial operation. The NETZSCH 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, the system features unrivaled performance over an unmatched temperature range. The GHP principle is based on an absolute measurement method and therefore requires no calibration standards. Combining cutting‐ edge technology with the highest quality standards, NETZSCH has designed a robust and easy‐to‐ operate instrument, featuring unparalleled reliability and optimum accuracy over a wide temperature range. The Guarded Hot Plate is an absolute method The great advantage of the GHP method is that it is an absolute method; i.e., no calibration or correction is required at all. The thermal conductivity values result in the stationary state simply from the: precisely measured total power input into the hot plate, Q average sample thickness, d, measurement area, A, and mean temperature difference, ΔT, along the sample or the two samples, as the case may be (the factor 2 results for two samples). Guarded Hot Plate - Principle of Operation The hot plate and the guard ring are sandwiched between two samples of the same material and approximately the same thickness, d. Cold plates are placed above and below the samples. All plate temperatures are controlled such that a well‐ defined, user‐selectable temperature difference, ΔT,
