Constant Temperature And Humidity Test Chamber Features
1. Unique design of the chamber within the wind circulation structure to ensure uniformity within the box within ± 2 ℃ under the test case conditions.
2. New PWM cold control technology to achieve low-temperature energy-saving operation. In low-temperature working conditions, the heater does not participate in the work through the PWM technology to control the refrigeration unit refrigerant flow and flow, the cooling pipe, cold bypass pipe, and hot bypass pipe three-way flow adjustment. To achieve the automatic constant temperature of the studio. This mode can achieve a 40% reduction in energy consumption at low temperatures.
3. Temperature synchronous slope control (IEC68-2-56, 68-2-30), no dripping, and no condensation.
4. The refrigeration room is fully sealed and soundproofed to reduce machine noise, box resonance, and machine noise control within 75.
5. The protection system consists of a dehumidifying evaporator, which prevents condensation from forming on the specimens as they heat up after tests at low temperatures.
Humidity And Temperature Test Chamber Applications
The constant temperature and humidity test chamber is experimental equipment used to simulate specific temperature and humidity conditions. It is suitable for various applications, including electrical appliances, communications, instrumentation, automobiles, plastics, metals, food, chemicals, building materials, medical, and aerospace.
Material testing
Constant temperature and humidity test chambers are widely used for durability, stability, and performance testing of materials. They can test tensile strength, wear resistance, corrosion resistance, and other properties of materials under different temperature and humidity conditions.
Electronic product testing
The performance of electronic products under different temperature and humidity conditions is crucial to their reliability and durability. The constant temperature and humidity test chamber can test the working performance and stability of electronic products such as mobile phones, tablet computers, automotive electronic equipment, etc., in high-temperature, low-temperature, or humid environments.
Drug stability testing
Drugs must meet specific temperature and humidity conditions during storage and transportation to ensure stability and effectiveness. The constant temperature and humidity test chamber can simulate drug storage under different environmental conditions and test their stability and shelf life.
Food quality control
Food preservation and storage under different temperature and humidity conditions will affect quality and safety. The constant temperature and humidity test chamber can be used to simulate environmental conditions in different seasons or regions and test food’s storage stability, freshness effect, and quality changes.
Auto parts testing
Auto parts need to perform well and be reliable under various extreme conditions, including high temperature, low temperature, and high humidity environments. The constant temperature and humidity test chamber can be used to test automobile parts’ working status and stability, such as engine parts, lights, instrument panels, etc., under different environmental conditions.
Building Materials Testing
Building materials must maintain stability and durability in various weather conditions. Constant temperature and humidity test chambers can check the performance and durability of building materials, such as concrete, paint, asphalt, etc., in high, low, or humid environments.
