Product SummaryWalk-in environmental chamber designed for temperature and humidity stability testing. Available in modular foam-panel construction or fully welded solid rooms. Configurable internal dimensions and layout to accommodate complete products and laboratory workflows.
Design Types- Modular walk-in chambers: foam-panel construction assembled on site for flexible room sizes.
- Welded (solid) walk-in chambers: fully welded structure for extended temperature/humidity ranges and faster change rates.
THR Series — OverviewTHR Series is a temperature-humidity walk-in room featuring integrated piping and ductwork, an all-in-one touchscreen controller and PLC functions. Room configuration, insulation, and internal fittings are customizable to match DUT size and test procedures. Typical sectors include electronics, automotive, LED, PCB and appliance testing.
Key Features- PID temperature and humidity control with closed-loop regulation for stable conditions.
- Programmable profiles: up to 100 patterns × 999 segments with ramp-rate control.
- Real-time humidity sensor for accurate feedback control.
- Independent overheat thermostat to protect samples and chamber.
- 50 mm cable test port for routing cables to DUT during tests.
- USB data export for logging and traceability.
- Double-glazed heated observation window with interior lighting (anti-sweat).
- External water supply for humidifier with auto-recycle capability.
Standards & Applications- Supported standards: IEC 68-2 series, MIL-STD-810F/G, ISO 16750-3 and related environmental test standards.
- Applications: whole-product reliability testing for computers, displays, printers, LED/PCB assemblies, automotive components, household appliances, telecom equipment, R&D and certification laboratories.
Safety & ProtectionSeven independent protection layers including grounding, leakage/break detection, heater short-circuit protection, blower motor overload protection, compressor over-voltage/overload protection and water shortage protection.
On-site Installation & SupportOn-site installation and commissioning services available (site-dependent). Support covers site layout and utilities planning, assembly and connections, temperature/humidity calibration, operator training and handover.
