Product Introduction

Product Features:

Wide Temperature Range
Broad-range testing: Capable of simulating extreme high and low temperature environments, typically ranging from -70°C to +150°C, meeting various product requirements for heat and cold resistance
Temperature uniformity and precision: Equipped with a high-precision temperature control system to ensure uniform temperature distribution, with accuracy typically reaching ±0.5°C or better

Air Pressure Regulation Function
Low-pressure simulation: Simulates low air pressure environments found in high-altitude regions, enabling effective testing of product performance under plateau or aerospace conditions
Precise control: Air pressure can generally be adjusted down to 0.5kPa or lower, maintaining a stable pressure level to simulate real low-pressure environments

Fast Temperature Ramp Rate
High efficiency in heating and cooling: Features rapid temperature rise and fall capabilities, with some models achieving several degrees Celsius per minute to support rapid environmental change testing
Programmable temperature profiles: Allows custom temperature change curves to simulate complex environmental transitions

Material and Structural Design
High-durability materials: Internal structures are typically made of corrosion-resistant stainless steel to ensure stable long-term operation under extreme temperatures and low pressure
Multi-layer insulation design: The chamber body offers excellent thermal insulation to reduce temperature fluctuations and energy consumption, enhancing testing accuracy

Modular Design
Flexible expandability: Some models feature modular configurations, allowing users to add functions such as humidity control or vibration testing for multi-condition testing
Easy maintenance and upgrades: Modular design simplifies repair, maintenance, and system upgrades, lowering long-term operating costs

Multi-function Integration
Synchronized temperature and pressure control: High/low temperature and low-pressure systems can operate simultaneously, enabling simulation of complex conditions such as low-temperature and low-pressure environments at high altitudes
