Product Overview
Walk-in Temperature & Humidity Test Chamber THR Series is a walk-in temperature and humidity room designed for humidity and heat tests, high/low temperature tests and combined temperature cycling of industrial products. Internal dimensions are customizable to allow whole-product testing without disassembly. The chamber provides precise temperature and humidity control for reliability and accelerated-aging tests.

Key Uses & Overview
The THR Series features integrated piping/duct layout, an all-in-one touch control panel and a programmable logic controller. Room dimensions, door type and utilities are configured to match DUT size and laboratory layout. Typical applications include electronics, automotive components, LED assemblies, PCBs and household appliances for whole-product reliability testing.

Features

• Customization: Internal dimensions and layout built to DUT and lab requirements.
• Temperature grades A–F for low temperatures down to −70 °C; standard high temperature to 80 °C (80–150 °C optional).
• Walk-in access door enabling testing of assembled products on carts or fixtures.
• Multiple independent protection layers for power, motor, compressor, heater and water supply.

Built-in Functions

• PID Temperature & Humidity Control — stable closed-loop regulation across the chamber.
• Programmable Profiles — up to 100 patterns × 999 segments with ramp-rate control.
• Humidity Sensor — real-time closed-loop humidity measurement.
• Overheat Thermostat — independent cutoff protection.
• 50 mm Cable Test Port — routing for cables to DUT during tests.
• USB Data Storage — export test logs to USB flash memory.
• Double-Glazed Observation Window — heated, sweat-proof viewing with interior lighting.
• External Water Supply — refillable humidifying pot with auto-recycle option.

Standards
Supports common environmental test standards including IEC 68-2-1 (Cold), IEC 68-2-2 (Dry Heat), IEC 68-2-3 (Damp Heat — Steady State), IEC 68-2-30 (Damp Heat — Cyclic), IEC 68-2-14 (Change of Temperature), MIL-STD-810G/F and ISO 16750-3.

Safety & Protection
Multi-layer protection includes grounding, leakage/breakage detection, heater short-circuit protection, blower motor overload protection, refrigeration over-voltage/overload protection and water shortage protection.

On-site Installation & Service
On-site installation and commissioning cover site layout and utility planning, chamber assembly and connection, temperature & humidity calibration, operator training and handover. Typical lead time for custom walk-in chambers: 30–40 working days from confirmed drawings.
