TemperaturFeuchteChamber

TemperaturFeuchteChamber, commonly referred to as a temperature-humidity chamber, is a laboratory device that creates controlled environmental conditions of temperature and relative humidity for testing materials, components, and products. The unit consists of an insulated chamber, a heating system, a cooling or refrigeration circuit, a humidity generation subsystem, and sensors to monitor conditions. Temperature is controlled by heating elements and, for cooling, a compressor-based refrigeration loop or thermoelectric modules; humidity is produced via steam, ultrasonic, or evaporative methods and removed by dehumidification as needed.

A programmable controller and software enable precise setpoints and test profiles, including constant conditions, cyclic temperature-humidity programs, ramp rates, dwell times, and conditioned exposure sequences. Uniform climate within the chamber is achieved by air circulation fans and careful airflow design to minimize gradients.

Typical configurations include benchtop, reach-in, and walk-in chambers, varying mainly in capacity and accessibility. The devices are widely used to evaluate product performance under environmental stress, such as electronic component reliability, polymer and coating stability, textile endurance, pharmaceutical packaging, and automotive parts.

Standards governing environmental tests often reference IEC 60068-2-series for temperature- and humidity-related tests, and users follow calibration protocols to ensure traceability. Common specifications cover temperature ranges from subfreezing to moderately high temperatures and relative humidity from dry to saturated conditions, with consideration of condensation and frost.

Maintenance involves regular calibration of temperature and humidity sensors, checking seals and insulation, cleaning condensate drainage, and verifying safety features like over-temperature protection and alarms. Proper documentation and routine validation are essential for reproducible results.
