Frequently Asked Questions (FAQ)
1. What is a temperature humidity chamber used for?
A temperature humidity chamber is used to simulate controlled environmental conditions by combining temperature and humidity. It helps manufacturers evaluate product reliability, durability, and performance under accelerated aging, storage, transportation, and operational conditions. These chambers are widely used in the electronics, automotive, aerospace, battery, medical device, and semiconductor industries.
2. What temperature and humidity ranges are available?
Most standard temperature humidity chambers provide:
Temperature range: -70°C to +180°C (custom models up to +200°C)
Humidity range: 20%–98% RH
Temperature stability: up to ±0.3°C
Humidity stability: up to ±2% RH
The exact specifications depend on the chamber size, refrigeration system, and testing requirements.
3. Which international standards require temperature humidity testing?
Many industries perform temperature humidity testing according to international standards, including:
IEC 60068
MIL-STD-810
JEDEC JESD22
ISO 16750
ASTM standards
RTCA DO-160
These standards define environmental test procedures for electronics, automotive components, aerospace equipment, batteries, and industrial products.
4. How do I choose the right temperature humidity chamber?
When selecting a chamber, consider:
