Product Introduction

Low-pressure test chamber is a precision testing device that uses a vacuum system to evacuate the air from a sealed chamber, creating an environment below standard atmospheric pressure. This chamber is primarily used to simulate extreme environmental conditions such as low pressure, low oxygen, and low temperature at high altitudes to evaluate the performance, reliability, and safety of products under these conditions. The high altitude test chamber adopts a modular, integrated design, consisting of a front insulated chamber, a rear cooling and vacuum device, and an electrical controller located on the chamber door.

Application areas

Altitude simulation chamber is widely used in aerospace and defense, automotive, consumer electronics and communications, medical and pharmaceutical, shipbuilding and marine engineering, oil and chemical, energy (photovoltaics and power), packaging and transportation, general high-altitude environments and industrial fields.

Product Main Advantages

Material and Structure: The inner cavity of the test chamber comes into direct contact with the test samples, therefore requiring excellent corrosion resistance, high strength, and superior airtightness. Use SUS304 stainless steel as the inner cavity material. The outer shell primarily serves structural support and protection, using high-quality A3 steel plate treated with electrostatic powder coating or powder coating to form a rust-proof, wear-resistant, and aesthetically pleasing protective layer.
Intelligent Programmable Control: The control system employs a human-machine interface combining a PLC and a color touchscreen, supporting multi-segment programmable control. Temperature and pressure parameters can be independently programmed and run synchronously, achieving fully automatic control. PID parameter self-tuning ensures the temperature control system maintains optimal performance under various operating conditions.
High-Efficiency and Energy-Saving Design: Utilizing a multi-layer composite insulation structure composed of high-strength polyurethane foam resin and high-density glass fiber cotton, it features low heat storage and low heat loss. Compared to traditional single-layer insulation structures, this composite insulation system significantly reduces energy consumption in both cooling and heating systems, resulting in energy savings and environmental friendliness.
Multiple Safety Protection Mechanisms: Low-pressure test chamber integrates multiple safety protection mechanisms, including independent over-temperature protection, an explosion-proof observation window, an emergency pressure relief valve, leakage protection, short-circuit protection, overheat protection, and motor overload protection. Dual pressure sensors provide redundant monitoring and automatically replenish gas in abnormal situations, ensuring the safety of the equipment and operators.
Multi-environment composite simulation capability: Low-pressure test chamber can simulate multiple environmental conditions individually or simultaneously, such as low pressure, high temperature, low temperature, and humid heat, thereby achieving precise control of temperature-pressure coupled environments..

Low-pressure test chambers are core testing equipment for simulating extreme environmental conditions such as high altitude, high temperature, and vacuum. Based on a vacuum system, they can simulate single-factor or multi-factor complex environments such as low pressure, high temperature, low temperature, and high humidity through precise temperature control and pressure regulation.

FAQ

Q1:What pressure range can the chamber achieve?

The standard system can reach a vacuum level down to 1×10⁻³ mbar (depending on pump configuration). Custom high‑vacuum or ultra‑high‑vacuum versions are available upon request.

Q2: Can I observe samples during testing?

Yes. The chamber is equipped with a transparent viewing window and internal illumination for easy monitoring of samples without breaking vacuum.

Q3: How do I maintain the vacuum pump and chamber?

Regular pump oil changes and periodic cleaning of the chamber interior are recommended. The viewing window should be cleaned with a soft, non‑abrasive cloth. A detailed maintenance manual is provided.

Q4: What standards does the chamber comply with?

It complies with GB/T 2423.21 (low‑air‑pressure test for electrical and electronic products) and IEC 60068‑2‑13 (environmental testing – low air pressure).
