Deep cold at -60C combined with humid-heat cycles does not fit ordinary small chambers; slow ramp rates push test schedules back; humidity fluctuation beyond limits invalidates data; and a midnight power cut restarts the whole programme from zero.
Internal chamber 1000x1000x1000mm (1000L), external approx. 1550x1950x1550mm; temperature -60C to 150C with 0.5C fluctuation and within 2C deviation; heating to 150C in about 40 minutes and cooling to -60C in about 60 minutes unloaded; humidity 20 to 98 percent RH with 3 percent fluctuation and within 3 percent deviation; fully sealed compressor with R404A green refrigerant, finned condenser with cooling fan and multi-stage evaporator with automatic load adjustment; 7-inch Chinese touch controller with programmable temperature-humidity profiles, multi-group PID auto-tuning, wet-dry bulb auto correction, 0.1C and 1 percent RH accuracy and 0.1-9.9 settable ramp; up to 100 programs and 5000 segments with 9999 repeats per command and 0-530h59min per segment; power-fail memory with automatic resume; SV/PV display, live profile curves, remaining time, cycle count and screen lock; SUS304 interior, matte stainless or painted steel exterior, polyurethane and glass-wool insulation; 50mm test port, 260x340mm triple-vacuum-glass window, SUS304 perforated shelves and RS-232 port; AC380V/50Hz about 9.5kW.
