THERMAL SHOCK TEST CHAMBER – VHAGAR SERIES
The VHAGAR series is the DOT platform dedicated to rapid thermal shock testing, designed to subject materials, components, and devices to extreme and repeated temperature variations.
VHAGAR chambers allow severe thermal stresses to be simulated in accordance with the main international standards:
- IEC 60068-2-14
- MIL-STD-810 (Method 503)
- MIL-STD-883
They are intended for test laboratories, R&D departments, and validation in the automotive, aerospace, defense, electronics, and telecommunications sectors.
VHAGAR chambers are available in:
Dynamic configuration (2-zone system)
With a motorized basket transferring the specimen between hot and cold chambers.Static configuration (3-zone system)
With a fixed test area and thermal shock generated by controlled switching of hot and cold airflow (required when the DUT must remain electrically or mechanically connected).
The system is equipped with a proprietary DOT 10” Touch Panel with ClimaLogic® software.
