Emission gas analysis opacity meter TRD 908

for exhaust gaswith LED light source

Overview
The TRD 908 is a smoke density test device (light measurement system) for determining smoke production of materials during thermal decomposition. It supports measurement procedures referenced in DIN 50055, ISO 3182 and ISO/TS 19850 and can be used as a stand-alone instrument or integrated into fire testing and exhaust duct systems.

Key functions & usage

• Selectable display mode for optical transmission and/or optical smoke density
• Integrated Single Board Computer (SBC) with embedded Windows, dedicated TRD software and a high-resolution 7" color touch display for standalone operation
• Interfaces and analog outputs for connectivity to peripheral devices and easy export of measurement data
• Designed for use in fire testing setups and for optical measurements in exhaust duct installations

Available versions

• TRDA — light source: 10 W halogen point light emitter (RDG)
• TRDL — light source: helium-neon laser (HeNe)
• TRD_LED — LED light source (for measurements according to ISO/TS 19850)
