With a wide temperature range of -70°C to 150°C and a humidity accuracy of ±1.5%RH, how does this device reshape product reliability testing standards?
As an "all-round player" in the field of environmental simulation, the constant temperature and humidity test chamber achieves the ultimate accuracy of temperature
fluctuation ≤±0.5℃ and humidity deviation ≤±1.5%RH by integrating cascade refrigeration system, PID+fuzzy control algorithm and fully isolated humidification technology.
Its core advantages include:
Wide temperature range coverage: supports extreme temperature testing from -70℃ to 150℃, meeting high-demand scenarios such as aerospace materials and military
electronics;
Intelligent humidity control system: using capacitive humidity sensor and rotary dehumidification module, it can achieve ultra-wide adjustment from 5%RH to 98%RH,
solving low humidity requirements such as drug stability testing;
Energy-saving and safety design: Cascade refrigeration technology saves 36% energy compared to traditional solutions, equipped with independent temperature limit alarm,
water and electricity separation structure and explosion-proof observation window, and passed international certifications such as EU CE and ISO 16750-4.
Five systems work together to achieve millisecond-level response
Refrigeration system:
Adopting French Taikang compressor and R404A/R23 cascade refrigeration, the COP value reaches 0.612 at -70℃, which is 40% higher than the single-stage refrigeration efficiency;
The evaporative condenser design realizes the utilization of heat gradient, and the cooling rate reaches 15℃/min.
Heating system:
Nickel-chromium alloy electric heater cooperates with bottom plate auxiliary heating, the heating rate is 8℃/min, and the temperature uniformity is ≤±1.2℃;
Intelligent power regulation technology avoids local overheating and prolongs the life of the equipment.
Humidity control system:
Electrode steam humidifier is linked with condensation dehumidification, and the humidity response time is less than 30 seconds;
The exclusive patented shallow groove humidification structure prevents scale deposition, and the maintenance cycle is extended to 180 days.
Air circulation system:
Multi-blade centrifugal impeller and variable frequency motor combination, wind speed 0.5-2.5m/s adjustable, ensure uniformity of temperature and humidity field;
Anti-aging silicone rubber sealing strip and polyurethane insulation layer reduce heat loss to 0.8W/(m·K).
Intelligent control system:
10.1-inch LCD touch screen supports 150 sets of program segment settings, and the data recording interval can be adjusted to 1 second;
Remote monitoring is achieved through RS485/Ethernet interface, compatible with development environments such as LabVIEW and Python.
Driven by smart manufacturing and carbon neutrality, constant temperature and humidity test chambers are evolving from a single testing tool to a "digital twin base" for product innovation. Through continuous technology iteration and service upgrades, Chinese manufacturers have occupied 38% of the global market, and the industry scale is expected to exceed 6.5 billion yuan in 2026. Choosing a device that combines precision, efficiency and reliability will become a key decision for companies to break through technical barriers and seize market opportunities.
