TRDA – Smoke Density Test Device with Light Measurement System

Test device for determining the smoke production of materials during thermal decomposition in accordance with DIN 50055

The TRDA measuring device – thanks to its Integrated Single Board Computer with Windows operating system, TRDA software and highresolution color touch display – can be used in stand-alone mode for setting parameters and determining optical density and transmission. Interfaces and analog outputs enable connectivity to peripheral devices for the fast and easy export of data and facilitate use in existing fire testing systems. Comprehensive data analyses can be performed via an external PC or notebook. Optional accessories allow for use of the light measurement system on various types of exhaust duct systems and greatly simplify calibration, operation and cleaning of the components.
