TDW 4240

Test Chamber for Determining the Stationary Heat Transfer Properties with a Controlled Hotbox in Accordance with DIN EN ISO 8990, DIN EN 1946-4, DIN EN ISO 12567, DIN EN 12412-2, and ASTM C1363; and Combined in Accordance with DIN EN 1934

The compact test chamber TDW 4240 is designed for testing elements and components used in construction, such as windows, profiles, doors and domes and brick walls).

They basically simulate the temperature and the natural convection inside and outside a building. Optionally, the humidity level in the two sections of the chamber can be set as needed. The HotBox software at the measurement and control unit is used to set all parameters as well as for complete data logging, detailed analysis and printing of test reports. There are also other devices, accessories and materials available that allow for sample preparation and conditioning to optimize the testing procedure.
