Three-layer Temperature Humidity Test Chamber

The main value of the three-layer design is sample organization and higher test throughput. It helps laboratories run more validation tasks in one compact footprint while keeping test groups clearly separated.

Key features:

• •Three stacked test layers in one chamber.
• •Higher sample capacity without adding multiple chambers.
• •Suitable for batch comparison and grouped sample testing.
• •Helps reduce queue time for routine validation.
• •Practical for R&D labs, QC rooms, and inspection centers.
• •Layer configuration can be selected according to test requirements.

This structure is especially useful when test demand is frequent, sample size is small, and engineers need to compare multiple sample groups under controlled temperature and humidity conditions.

As a multi-layer temperature humidity test chamber, this equipment simulates heat, cold, humidity, damp heat, and cyclic climate stress for product reliability evaluation.

Typical test modes:

• •High temperature testing.
• •Low temperature testing.
• •Constant temperature and humidity testing.
• •Damp heat testing.
• •Alternating temperature humidity testing.
• •Temperature cycling for small samples.
• •Storage and aging tests under controlled conditions.

Temperature range, humidity range, chamber volume, and control accuracy can be configured according to the selected model and test program.

The chamber is suitable for laboratories that need to test multiple small samples, product versions, or material batches under controlled temperature and humidity conditions. Engineers can organize tests by layer, batch, product model, or validation stage.

Typical applications:

• •Parallel reliability testing for multiple electronic components.
• •Batch comparison testing for PCBs, sensors, connectors, and small devices.
• •Same-condition testing for different material samples or coatings.
• •Product version comparison during R&D validation.
• •Incoming material inspection with grouped sample testing.
• •Routine quality control for small industrial components.
• •Laboratory test capacity expansion without adding multiple separate chambers.

This application logic is different from a standard or double-layer chamber: the main value is higher sample organization efficiency and better throughput for repeated validation work.

A three-layer chamber requires stable airflow and control logic across stacked test spaces. Depending on configuration, the layers can be designed for coordinated operation or independent control.

System highlights:

• •Programmable touchscreen controller.
• •Multi-step temperature and humidity profiles.
• •Optional independent layer control depending on model.
• •Layer-focused airflow design for test uniformity.
• •Optional RS232, RS485, or Ethernet communication.
• •Optional PC monitoring and data recording.
• •Built-in refrigeration system.
• •Modular refrigeration design for easier maintenance.

Final system configuration should be selected according to layer size, temperature range, humidity range, sample heat load, airflow requirement, and control mode.

The chamber can be configured to support test conditions related to common environmental and temperature humidity testing methods, including IEC 60068-2-1 low temperature, IEC 60068-2-2 dry heat, IEC 60068-2-30 damp heat cyclic, IEC 60068-2-78 steady-state damp heat, ISO 16750 automotive electronics, and MIL-STD-810 environmental testing.

Final compliance depends on the complete test method, sample type, sensor setup, calibration status, operating procedure, and third-party assessment.

Customization options:

• •Inner size and volume of each test layer.
• •Temperature and humidity range.
• •Independent or coordinated layer control.
• •Communication and data recording.
• •Viewing window and cable port.
• •Support frame or installation layout.
• •Power supply by destination country.
