Climatic Chamber/ Temperature &Humidity Chamber/ Environmental Simulation Chamber
Environmental tests are used to let manufacturers find potential defects to be corrected before the production stage, ensuring:
• Reliable products
• Lower maintenance costs
• Satisfied Customers
The operating principle of a testing chamber can be explained by two physical parameters that the environmental test chamber can control: temperature and humidity.
Selection of a climatic chamber
Temperature range
Highest temperature: For chamber manufacturer, highest temperature +150 ℃/+180 ℃ for small chamber and +100 ℃ for walk-in chamber is the standard highest temperature limit.
Lowest temperature: -40 ℃ is the intersection point to adopt single stage cooling system and cascade cooling system (with -70 ℃ lowest temperature), which has significantly impact on price and power consumption.
Temperature changing rate
• Method 1: Define the time duration from one temperature to the other;
• Method 2: Define the linear rate from one temperature to the other;
• Method 3: Define the temperature rate from one temperature to the other according to IEC60068-3-5, only the middle 80% range is calculated：
Heat compensation capacity
Heat compensation capacity: to compensate the heat from the test specimen
Humidity range
Define the temperature range to control humidity, related humidity range and dew point range; For example:
– Humidity range: 10% ～98%RH@ +10 ℃ to +90 ℃
– Dew point: +4 ℃ ～+88 ℃
