EziLab offers the Temperature Test Chamber EZL-TC157, a 22 L benchtop environmental chamber that runs from -40°C to 150°C with temperature fluctuation within 0.5°C and uniformity within 2°C. It heats from 25°C to 130°C within 30 minutes and cools from 25°C to -40°C within 45 minutes, using a compressor refrigeration system and an independent NiCr heater. A SUS304 stainless steel interior, consistent air circulation, and fiberglass and polyurethane insulation complete the build. A 7-inch programmable touchscreen stores multi-step profiles, turning the unit into a temperature cycling chamber for hot-cold ramps and dwell tests on boards, sensors, and small components that fit the 300 by 250 by 250 mm workspace. Long-term data recording with RS485 download supports test reports, a viewing window lets staff check samples mid-run, and over-temperature protection guards long cycles in this thermal test chamber. Electronics and semiconductor makers use it as a thermal cycling chamber to screen parts for solder fatigue and cold-start faults, while telecommunications and automotive component suppliers validate modules before release. Aerospace, pharmaceutical, and quality control labs run routine qualification tests on small samples. Its 22 L size suits single-part studies. See the Temperature Test Chambers and Temperature Test Chamber pages for full specifications.
