The Walk-in Constant Temperature and Humidity Test Chamber is suitable for conducting accelerated humidity and heat testing, cyclic humidity and heat testing, and constant humidity and heat testing on large components, semi-finished products, electronic and electrical equipment, precision instruments, lithium batteries, chemical products, automotive parts, and pharmaceuticals. It can also be used for constant temperature and humidity storage in warehouses and production under workshop conditions, enabling analysis and evaluation of product performance and behavior under simulated environmental conditions during testing.
Standards
GB/T2423.3 Environmental Testing of Electronic and Electrical Products Ca: High Temperature Test Method
GB10589-89 Technical Conditions for Low Temperature Testing
GB/T2423.4-93.507.2 Alternating Humidity and Heat Test
GB/T2423.3-93 Constant Temperature and Humidity Test Method
GB5170.5.-96 Requirements for “Verification Methods for Basic Parameters of Environmental Test Equipment for Electrical and Electronic Products”

Features
1. Mechanical Structure: Primarily composed of an electrical control system, insulated chamber system, air circulation system, heating system, humidification and water circuit system, refrigeration and dehumidification system, etc.
2. Utilizes modular insulated chamber panels, allowing for arbitrary expansion of internal volume. Easy to assemble and disassemble, with dimensions customizable by the customer.
3. The interior features SUS#304 stainless steel panels, while the exterior utilizes Baosteel A3 powder-coated steel for an aesthetically pleasing finish. Insulation layers employ PU foam or rock wool.
4. The control system incorporates imported single-point or programmable controllers with a user-friendly interface, allowing flexible parameter settings for convenient operation.
5. Refrigeration units incorporate imported European/American compressors with eco-friendly refrigerants. A dual-circuit low-temperature system design employs separate compressors for different temperature zones, extending equipment lifespan.
6. Large observation windows in interior doors facilitate monitoring of test samples.
7. The left side of the unit features a 50mm diameter test port for connecting external power or signal cables (port size and quantity are optional).
8. Utilizes imported fan motors + high/low-temperature resistant aluminum alloy circulation fans. High-quality centrifugal fans ensure powerful air circulation, eliminating dead zones and achieving uniform temperature distribution throughout the test chamber.
9. Equipped with advanced safety and protection devices: earth leakage circuit breaker, over-temperature protector, phase failure protector, water shortage protector, low-water protection, short-circuit protection, current overload protection, along with audible/visual alarms and SMS alerts.
