KBT – Fire-Testing System for Cables

Fire-testing system for measuring the heat release and smoke production during flame spread tests on vertically mounted bunched cables and insulated wires, in accordance with EN 50399 and IEC 60332-3-10 (testing device)

The KBT from NETZSCH TAURUS Instruments GmbH is easy to operate, offering innovative control and data acquisition options in an intuitive format with ample user guidance.
The high-resolution color touch display on the “KBT Control” cabinet allows for measuring and control with the integrated Single Board Computer, Windows operating system and KBT software. There is thus no longer any need for manual controls such as switches, controllers or buttons; the status of the
testing system is clearly displayed and the system prevents any critical operating errors. The storage, analysis and recording of all test data is handled entirely via the control unit. Well thought-out details along with the use of highquality materials guarantee the KBT test system a long product life and a low degree of wear and tear.
