A product may perform perfectly in the laboratory but fail when exposed to heat, humidity, cold storage, transportation, or seasonal climate changes. Electronics can suffer condensation, coatings may peel, plastics can deform, and sensors may drift out of calibration. Manufacturers therefore need a reliable way to recreate real environmental conditions before products reach the market.
LIBTemperature Humidity Chambersare designed to reproduce real-world climate conditions with high accuracy and repeatability. By precisely controlling temperature, humidity, airflow, and test duration, these chambers help manufacturers verify product reliability, durability, and compliance with international testing standards across automotive, electronics, aerospace, pharmaceutical, and research industries.
1. How Does a Temperature Humidity Chamber Work?
Precise Temperature and Humidity Control
A Temperature Humidity Chamber creates controlled environmental conditions through a combination of refrigeration, heating, humidification, and dehumidification systems. High-precision PT100 Class A sensors continuously monitor chamber conditions with temperature resolution up to ±0.001°C.
The refrigeration system lowers chamber temperatures, while electric heaters maintain stable heating profiles. The humidity system generates moisture through controlled steam humidification and removes excess moisture through condensation. Together, these systems maintain temperature stability of ±0.5°C and humidity stability of ±2.5% RH throughout the test cycle.
Standard-Compliant Environmental Testing
Temperature humidity chambers are widely used for tests specified by international standards, including:
① IEC 60068-2-1 Cold Test
② IEC 60068-2-2 Dry Heat Test
③ IEC 60068-2-30 Damp Heat Cyclic Test
④ IEC 60068-2-78 Damp Heat Steady-State Test
⑤ ISO 16750 Environmental Testing for Road Vehicles
⑥ MIL-STD-810H Environmental Engineering Considerations
⑦ ASTM D4332 Conditioning Containers and Packaging
⑧ JESD22 Semiconductor Reliability Testing
These standards require highly controlled and repeatable environmental conditions to evaluate product performance under simulated climate exposure.
Industries That Depend on Climate Simulation
Temperature humidity chambers support product qualification, reliability verification, and quality control across many industries: Automotive components, Electric vehicle batteries, Consumer electronics, Telecommunications equipment, Aerospace systems. Medical devices, Pharmaceutical products, Solar energy equipment, Research laboratories.
Manufacturers use these chambers to evaluate corrosion resistance, aging performance, moisture sensitivity, thermal endurance, and long-term reliability before commercial deployment.
2. Vietnam Customer Expanded from a Reach-In Chamber to a 98m³ Walk-In Temperature Humidity Chamber
After several years of successful operation with a LIB reach-in temperature humidity chamber, a customer in Vietnam decided to expand their testing
capacity by purchasing a 98 cubic meter walk-in temperature humidity chamber.
The customer conducts performance testing and reliability validation for large industrial products. As production volume increased, the original chamber could no longer accommodate the growing number and size of test samples. A walk-in solution became the ideal upgrade.
Why the Customer Chose LIB Again
Large Testing Capacity
The 98m³ walk-in chamber allows operators to place large assemblies, multiple test racks, and oversized products directly inside the chamber. This significantly improves testing efficiency while reducing sample handling time.
High Accuracy and Stability
The chamber maintains excellent temperature and humidity uniformity through optimized airflow circulation and PID control technology. Multi-directional centrifugal fans help maintain temperature uniformity within ±1.5°C across the entire workspace.
Safe and Reliable Operation
Environmental testing often runs continuously for days or even weeks, making system safety and reliability essential. The walk-in temperature humidity chamber is equipped with comprehensive protection systems that continuously monitor chamber operation, including temperature control, refrigeration performance, humidification status, and water supply conditions. These intelligent safeguards help prevent equipment damage, protect valuable test specimens, and minimize unexpected downtime during long-term testing. Designed to comply with CE requirements as well as internationally recognized IEC and CSA electrical safety standards, the chamber provides dependable and secure operation for
laboratories, manufacturers, and testing facilities.
Cost-Effective Investment
Compared with building multiple smaller chambers, the walk-in solution provides greater usable test volume, lower operating costs per sample, and simplified maintenance management.
Following installation and operation, the customer reported excellent chamber performance and stable test results. Several government organizations and industrial laboratories that visited the facility have also entered discussions regarding similar chamber purchases due to the equipment's performance, safety features, and operational efficiency.
3. LIB 250L Temperature Humidity Chamber vs Walk-In Temperature Humidity Chamber
Choosing between a reach-in chamber and a walk-in chamber depends on sample size, testing volume, and future expansion plans.

How to Choose
Choose a 250L Temperature Humidity Chamber if:
• Testing small products or components
• Limited laboratory space
• Lower sample volume
• Budget-sensitive projects
Choose a Walk-In Temperature Humidity Chamber if:
• Testing large assemblies
• High-volume testing requirements
• Multiple samples tested simultaneously
• Future production expansion is expected
For many manufacturers, starting with a reach-in chamber and later upgrading to a walk-in chamber provides the best balance between investment and testing capacity.
