Climate chamber THR

thermostatictemperaturehumidity

Overview
The THR Series (Temperature Humidity Room) is a walk-in chamber engineered for large parts and machinery requiring combined temperature and humidity control. The room integrates pipe and duct systems, an all-in-one touch-screen control panel and a programmable logic controller. Internal dimensions, temperature and humidity ranges, and special options are customizable to suit DUT size and laboratory layout.

Key Capabilities

• Precise low-humidity control down to 5% R.H. (special option with dehumidifier).
• Six selectable low-temperature grades (A–F) down to −70 °C; standard high-temperature up to 80 °C (80–150 °C optional).
• PID control for temperature and humidity with real-time humidity sensor and USB data storage for test export.
• Programmable profiles: 100 patterns × 999 segments each, supporting ramp-rate control.
• 50 mm cable test port for routing cables to the DUT during test cycles.
• Double-glazed heated observation window with interior lighting.
