Programmable Constant Temperature and Humidity Test Chamber

The programmable constant temperature and humidity test chamber is an essential testing device widely used in aerospace, automotive, home appliances, chemical industry, and scientific research. It is designed to simulate various environmental conditions—including high/low temperature, high/low humidity, and alternating temperature-humidity cycles—to test the heat resistance and cold resistance of materials, components, or instruments, as well as any potential damage caused under such conditions. Typical applications include testing electronic instruments, new materials, electrical appliances, vehicles, metals, electronic products, and aerospace materials under conditions of transportation, storage, and use.

Technical Specifications


Product Features:


  • Three power-off mode options: power recovery, stop, or restart

  • Made of SUS304 stainless steel, resistant to acids and corrosion, and easy to clean.

  • Insulation layer is made of integrally foamed polyurethane, which is lightweight, durable, and corrosion-resistant. The chamber door is sealed with a magnetic strip, offering a neat appearance and high temperature control accuracy.

  • Equipped with a fully enclosed cooling unit, running smoothly with low noise. Heating is done via stainless steel finned heating tubes, which are rust- and corrosion-resistant.

  • Double-layer vacuum-strengthened glass with inner laminated sheet conductive films allows defrosting by heating and enables clear observation of the test process inside the chamber.

  • Features a non-reactive, explosion-proof door handle for simple, safe, and reliable operation.

  • High-quality universal casters with brakes are installed at the bottom, allowing easy relocation of the device and secure fixation.


  • Uses a precision programmable LCD temperature and humidity controller; intelligent digital PID microcomputer temperature control instrument.

  • The precision programmable LCD controller allows multiple-set and multiple-step programming, fixed-value or program operation, adjustable timing, and scheduled start/stop. After a power outage, the device can resume operation according to preset start/stop schedules.

  • Overtemperature protection and fan overheat protection.

  • Phase loss/reversal protection, cooling system overload protection, and cooling unit overpressure protection. 

  • Timed protection.

  • Dry-burn prevention.

  • Leakage detection, operation indicators, and automatic shutdown after fault alarms.
