What Makes Glove-Type High-Low Temperature Test Chambers Indispensable for Extreme Environment Testing?

    The glove-type high-low temperature test chamber is a key equipment for environmental reliability testing in electronics, automotive, aerospace and other fields. With the core advantages of "sealed isolation + precise temperature control + convenient operation", it has become an ideal solution for sample testing under extreme temperatures. Its core features can be summarized in the following six dimensions.

I. Wide-Range and Precise Temperature Control, Adapting to Diverse Testing Needs

    The equipment has a wide temperature range. Conventional models can simulate extreme environments from -70℃ to +150℃, and customized models can expand the temperature range to adapt to high and low temperature resistance testing of various products. It adopts PT100 platinum resistance sensor and PID high-precision control algorithm, with temperature fluctuation ≤±0.5℃ and uniformity ≤±2.0℃, ensuring accurate test data; the heating rate is 1.0-3.5℃/min and the cooling rate is 0.7-1.2℃/min, which can quickly switch temperatures and improve test efficiency.

II. Sealed Glove Operation, Ensuring Test Continuity and Safety

    The chamber is equipped with a sealed operation port and high-sealing silica gel gloves to form an isolated test environment. Operators can real-time complete sample testing, status observation and other operations through the gloves without interrupting the test, avoiding temperature and humidity fluctuations caused by opening and closing the door, and improving data reliability; at the same time, it blocks the impact of extreme temperature inside the chamber on the outside, prevents external impurities from entering, and ensures environmental cleanliness and operator safety.

III. Intelligent and Convenient Operation, Improving Test Efficiency

    The equipment is equipped with a large-screen touch screen controller, supporting Chinese-English bilingual switching and intuitive operation. The controller can preset 100 groups of processes, 50 steps/group of test procedures, and support 250 cycles of testing, meeting the needs of alternating temperature testing; it is equipped with USB and network communication functions, which can real-time export data, print curves and remote monitoring operations, facilitating data traceability and management; some models are equipped with test holes, which can be connected to external power supplies to realize live sample testing and expand application scenarios.

IV. Stable Structural Design, Ensuring Long-Term Stable Operation

    The chamber adopts a double-layer composite structure. The outer shell is made of A3 steel plate with electrostatic spraying, which is corrosion-resistant and durable; the inner tank is made of SUS304 mirror stainless steel, which is high-temperature resistant and easy to clean; the middle is filled with 100mm high-density glass fiber cotton insulation layer, which is heat-insulating and energy-saving. The chamber door is equipped with double-layer high-temperature resistant sealing strips and hollow tempered glass observation window. The observation window is equipped with conductive film heating defrosting function, taking into account both sealing and observation needs. The refrigeration system adopts fully enclosed unit and environmentally friendly refrigerant, with forced air cooling, stable operation and low noise. It has passed 48-hour air pressure leak test to ensure stability and reliability.

V. Comprehensive Safety Protection, Reducing Test Risks

    The equipment is built with multiple safety protection mechanisms, including over-temperature protection, refrigeration system overload and over-pressure protection, phase loss/phase reversal protection, leakage protection, water shortage protection, etc. It is equipped with three-color indicator lights to real-time display operation, standby and fault status. When a fault occurs, it will automatically shut down and prompt the cause, facilitating troubleshooting. The heating and refrigeration systems are independently designed to avoid interference, which not only improves temperature control accuracy, but also reduces the impact of single system failure on the test, ensuring equipment operation and sample safety.

VI. Compliance with Authoritative Standards, Adapting to Multi-Industry Needs

    The product strictly complies with national and international standards such as GB/T2423.1-2008, GB/T2423.2-2008 and IEC60068. It is widely used in electronics, electrical engineering, automotive, aerospace, biomedicine, building materials and other fields. It can complete high and low temperature and constant temperature performance testing of materials and products, providing support for product design improvement and quality verification.

    In summary, with the core advantages of precise temperature control, sealed operation, intelligence and convenience, and stability and reliability, the glove-type high-low temperature test chamber solves the pain points of dynamic testing under extreme temperatures. It is a key equipment for environmental reliability testing in multiple industries and provides solid guarantee for product quality improvement.
