GDW Temperature Test Chamber for reliable high- and low-temperature testing of electronic, automotive and industrial components.
The ITM-LAB GDW Series High and Low Temperature Test Chamber is designed for high-temperature, low-temperature, temperature cycling, and temperature endurance testing of electronic components, automotive parts, and industrial materials.
Available in 100L to 1000L capacities, with −40°C or −70°C to +150°C temperature configurations.
| Temperature Range | Capacity | Heating Rate | Cooling Rate |
|---|---|---|---|
| −40°C / −70°C to +150°C | 100–1000L | ≥3°C/min | ≥1°C/min |
Temperature fluctuation of ±0.5°C, temperature deviation of ±1°C, and temperature uniformity of ≤2.0°C support repeatable environmental testing under specified conditions.
A 7-inch touchscreen controller supports constant-temperature operation, multi-step temperature programs, scheduled testing, and historical data recording.
The chamber features a SUS304 stainless-steel interior, insulated cabinet, observation window, and forced-air circulation system for controlled temperature distribution.
Integrated protection functions cover chamber over-temperature, compressor operating faults, circulation fan overheating, electrical overload, and other abnormal operating conditions.
