Test chambers are core simulation and verification equipment in modern industrial and scientific research systems. They can independently and precisely control various parameters such as temperature, humidity, air pressure, light, vibration, and corrosive gases, creating a highly uniform and repeatable environmental field within the chamber. This capability not only significantly accelerates the natural aging process of products and efficiently exposes potential defects to improve quality, but also significantly shortens the R&D cycle, providing solid data support for product optimization and innovation. Test chambers serve numerous high-tech industries. In the electronics and semiconductor fields, they are used to test the performance and lifespan of circuit boards, chips, and end products under high temperature, low temperature, humid heat, and salt spray conditions. The automotive and aerospace industries rely on them for environmental stress screening (ESS) and reliability verification of components and complete machines, simulating harsh climates from polar cold to desert heat. In materials science, new energy R&D, and biomedicine, test chambers also provide an indispensable platform for aging, corrosion, light stability, and shelf-life testing of new materials, batteries, pharmaceuticals, and packaging.

Shanghai Dengsheng Instrument Manufacturing Co., Ltd. designs and builds environmental test chambers that reproduce temperature, humidity, UV radiation, and corrosive conditions for product validation across electronics, automotive, aerospace, and materials industries. As a Test Chamber Series manufacturer, we integrate precision control, robust construction, and data traceability into every unit.
We offer five core chamber types, each engineered for specific environmental stress testing. All models share a common foundation of PID control, 304 stainless steel interiors, and safety interlocks, but differ in their simulation focus.
Our chambers are used to expose products to controlled stress that accelerates failure modes, shortens R&D cycles, and provides data for design improvement. Typical applications include:
We build each chamber around your test profile. The control system uses a 7-inch touchscreen with 100 programs, 999 segments, and 999 cycles, supporting both constant and program modes. PID algorithms maintain temperature fluctuation within ±0.1°C to ±0.5°C, and humidity fluctuation within ±3% RH. For low-temperature models, we use a binary cascade refrigeration circuit with a fully enclosed Tecumseh compressor, ensuring rapid cooling and stable performance down to -70°C.
Air circulation is designed with multi-blade fans and return-air ducts to eliminate dead zones, achieving temperature uniformity of ±2°C. The inner chamber is 304 stainless steel, and the outer shell is cold-rolled steel with electrostatic coating. Insulation is 100 mm polyurethane foam, preventing condensation on external surfaces.
Our production facility spans 8,000 m² and follows ISO-9001 quality management, with a 4-stage inspection process: incoming material, in-process, aging test, and final pre-shipment check. We conduct loaded uniformity mapping before delivery, so performance values reflect real operating conditions. Each chamber is tested for temperature and humidity uniformity, safety alarms, and controller functionality before packing.
| Model | Temperature Range | Humidity Range | Volume (L) | Key Feature |
|---|---|---|---|---|
| HLT-100/150/225/408 | -20 to +150°C (Type I), -40 to +150°C (Type II), -60 to +150°C (Type III) | — | 100, 150, 225, 408 | Binary cascade refrigeration, 7-inch touchscreen |
| HLTS-100/150/225/408 | Same as HLT | 30–98% RH | 100, 150, 225, 408 | Humidity control, separate water and electrical circuits |
| UV Aging Chamber | RT+10°C to 70°C | ≥90% RH (condensation) | 1100×550×400 mm (working space) | 8 UVA-340 lamps, irradiance adjustable to 2.0 W/m² |
| Ventilation Aging Chamber | Up to 200°C (typical) | — | Customizable | Stainless steel inner lining, forced air circulation |
| Cyclic Immersion Corrosion Chamber | Ambient to 50°C | — | Customizable | Automated immersion cycles, corrosion-resistant construction |
All chambers include a 7-inch color touchscreen controller with Ethernet remote control (optional), USB data export, and multi-language support. The controller logs running curves, alarms, and program status. For integration into existing test systems, we provide optional RS-485 or Ethernet interfaces, and we can adapt the control protocol to your MES or SCADA environment.
We supply installation guidance and remote commissioning support via video conference. Each unit comes with an operation manual, and we offer online training for operators. Maintenance is simplified by accessible components: the refrigeration system is modular, and the humidification lines are separated from electrical circuits to reduce failure risk. Spare parts such as lamps, sensors, and compressors are available for quick replacement.
To prepare a precise quotation and technical proposal, we need the following project inputs:
Our engineers use this information to match the correct compressor size, air circulation design, and control options, ensuring the chamber performs under your actual load conditions.
What is the difference between the HLT and HLTS series?
The HLT series provides temperature-only cycling, while the HLTS series adds humidity control (30–98% RH) for combined temperature-humidity tests. Both use the same controller and safety features.
Can you customize the chamber size or temperature range?
Yes. We offer non-standard customization based on your drawings or specifications. Our R&D team can adjust interior dimensions, temperature range, and even add special ports or viewing windows.
How do you ensure temperature uniformity under load?
We perform loaded uniformity mapping during the factory acceptance test. The air duct design uses multi-blade fans and return-air channels to minimize dead zones, and we adjust airflow deflectors based on your load configuration.
What is the typical delivery time for a standard chamber?
For standard models, we usually ship within 5–7 business days after payment. Customized units have a delivery schedule agreed in the contract, depending on complexity.
Do you provide international installation support?
Yes. We offer remote installation guidance via video, English documentation, and assistance with logistics and customs clearance. Our after-sales team provides lifetime technical support.
Our portfolio also includes Products, High and Low Temperature Test Chamber, View More for applications with different operating ranges, interfaces or integration requirements.
