Benefits

Precise Temperature and Humidity Control: The chamber uses advanced temperature and humidity control technology. The temperature range spans from -70°C to +180°C, with a humidity control range from 10% RH to 98% RH, offering high control precision to meet various stringent environmental testing requirements.

Large Capacity Design: The walk-in design provides ample testing space for large samples, making it suitable for large-scale batch testing or environmental adaptability tests for oversized products. It offers flexibility to accommodate different testing needs.

Efficient Humidification and Dehumidification Systems: Equipped with high-efficiency humidification and dehumidification systems, the chamber ensures rapid and stable temperature and humidity adjustments, maintaining stable testing conditions even in high or low humidity environments.

Environmental Uniformity: The built-in air circulation system ensures uniform temperature and humidity distribution throughout the testing space, preventing local fluctuations in temperature and humidity from affecting the test results.

Long-Term Stability: Made from highly durable materials, the walk-in temperature and humidity test chamber is resistant to high temperatures and humid conditions, ensuring long-term stable operation and reducing the likelihood of equipment failure.
