Vibration Testing Chambers

Specifications
Unlike the Benchtop Vibration Table, which focuses solely on vibration testing, Vibration Testing Chambers offer a more comprehensive functionality.  The DHT® Vibration Testing Chamber seamlessly integrates high-precision environmental control with mechanical vibration testing, enabling simultaneous simulation of temperature, humidity, and tri-axial vibration on a single platform.
This combined capability significantly enhances the realism and efficiency of reliability testing. Featuring a modular design, the chamber is compatible with a wide range of vibration table systems and supports sine, random, and shock vibration modes, making it ideal for aerospace, automotive electronics, and defense applications where stringent reliability standards are required. It offers a broad temperature range from -70°C to +180°C and maintains humidity control accuracy within ±2% RH. Powered by DHT®’s proprietary DHSPLCON™ intelligent control system, the chamber supports multi-step programming and real-time data feedback, ensuring excellent repeatability and long-term test stability.
The housing is constructed from corrosion-resistant composite materials, providing superior sealing and anti-interference performance. Advanced features such as safety interlocks, anti-condensation protection, and remote monitoring further ensure reliable operation under demanding multi-stress testing conditions.

Benefits

Integrated Multi-Stress Simulation：Combines precise environmental control (temperature: –70°C to +180°C; humidity accuracy: ±2% RH) with tri-axial mechanical vibration (sine, random, shock modes), enabling simultaneous testing for more realistic and efficient reliability validation.

Universal Vibration Table Compatibility：Modular design with adjustable height allows seamless integration with various vibration platforms, increasing flexibility for aerospace, automotive, and defense testing requirements.

Intelligent Control & Data Management：Powered by the DHSPLCON™ intelligent system and DOAHO software, supports multi-step programming, remote monitoring, and real-time data feedback. Robust data logging and PC connectivity streamline test analysis and reporting.

Durable & Secure Construction：Chamber housing uses corrosion-resistant composite materials with advanced sealing and anti-interference design. Integrated safety interlocks, anti-condensation systems, and multiple protection layers ensure safe operation in high-stress environments.

Proven Component Reliability：Utilizes high-quality components from globally trusted suppliers, ensuring long-term operational stability, minimal maintenance, and high repeatability even under extended test cycles.
