Climate chamber THR

thermostatictemperaturehumidity

Description
The THR Series walk-in temperature and humidity stability test chamber is engineered for whole-product environmental reliability testing of large automotive spare parts and assemblies. It provides combined temperature and humidity control in a customizable walk-in room to evaluate durability, performance and conformity under controlled climatic cycles.

Overview
THR Series — Temperature Humidity Room. Integrated pipe and duct design with an all-in-one touchscreen controller and PLC. Room dimensions, internal layout and configuration are customizable to match the device under test (DUT) and laboratory constraints. Suitable for electronics, automotive, LED, PCB, appliances, research labs and certification centers.

Features

• Customization: internal dimensions and room size built to DUT specifications; supports carts and fixtures for whole-product testing.
• Temperature grades: six low-temperature options (A–F) down to −70 °C; standard high temperature 80 °C (80–150 °C optional).
• PID temperature and humidity control for stable and accurate environmental regulation.
• Programmable profiles: 100 patterns × 999 segments with ramp-rate control.
• Real-time humidity sensing for closed-loop humidity control.
• Walk-in access for testing fully assembled parts and machinery.
• Safety: seven independent protection layers (power, motor, compressor, heater, water, etc.).
• 50 mm cable test port to route cables to DUT during testing.
• USB data export for test recording and traceability.
• Heated double-glazed observation window with interior lighting.
• External water supply with auto-recyclable humidifying pot; optional dehumidifier for extended humidity ranges.
