In modern laboratories, engineers often need to evaluate product performance under extreme heat, freezing temperatures, and varying humidity conditions. However, not every laboratory has enough space for a large walk-in or reach-in environmental chamber. This is why compact environmental simulation equipment has become increasingly popular across electronics, automotive, aerospace, and research industries.
LIB Portable Cold Heat Controlled Temperature Humidity Test Chamber provides precise temperature and humidity control in a compact footprint. It helps manufacturers perform reliable environmental testing while saving laboratory space, reducing installation requirements, and improving testing efficiency.
Electronic components are highly sensitive to environmental stress. Temperature fluctuations and moisture exposure can lead
to corrosion, solder joint cracking, PCB deformation, insulation failure, and shortened product lifespan.
A Portable Cold Heat Controlled Temperature Humidity Test Chamber is widely used to evaluate:
① Printed Circuit Boards (PCB)
② Sensors
③ Connectors
④ Semiconductors
⑤ Communication modules
⑥ Consumer electronics
Relevant standards include: IEC 60068-2-1 (Cold Test)， IEC 60068-2-2 (Dry Heat Test)， IEC 60068-2-78 (Humidity Test)， and JESD22-A101
The demand for portable chambers originated from R&D laboratories needing environmental simulation equipment directly beside development workstations. Engineers can immediately place samples into testing after design modifications, greatly shortening product development cycles.
Modern vehicles contain hundreds of electronic control units and sensors that must operate reliably under harsh environmental
conditions.
Portable temperature humidity chambers are commonly used for testing: ADAS sensors, Battery management systems, Automotive connectors, Cabin electronics, Charging system components, Electric vehicle control modules.
Applicable standards include: ISO 16750, LV 124, SAE J1455, IEC 60068 Series
Automotive manufacturers increasingly require compact testing equipment because development teams often conduct preliminary validation before sending products to large certification laboratories. Portable chambers allow faster screening and troubleshooting during product development.
Temperature and humidity directly affect pharmaceutical products, packaging materials, adhesives, coatings, and polymers.
Typical applications include: Drug stability studies, Packaging validation, Moisture absorption testing, Material aging studies, Accelerated shelf-life testing.
Relevant standards include: ASTM D4332, ASTM D3451, ISO 2233
The growth of biotechnology and laboratory research has created demand for environmental chambers that can fit inside clean rooms, research benches, and limited laboratory spaces while maintaining strict environmental control.
For semiconductor and electronic product performance verification, Intel selected environmental simulation equipment
capable of delivering stable and repeatable testing conditions.
The LIB TH-50 Portable Cold Heat Controlled Temperature Humidity Test Chamber successfully met Intel's testing requirements through several key advantages.
Intel required stable and repeatable environmental conditions to evaluate the performance of electronic components under temperature and humidity stress. The LIB TH-50 Portable Cold Heat Controlled Temperature Humidity Test Chamber delivered consistent testing environments with a temperature range from -70°C to +150°C and humidity control from 20%RH to 98%RH. By maintaining temperature fluctuations within ±0.5°C and humidity deviations within ±2.5%RH, the chamber supports environmental testing procedures based on IEC 60068 standards and helps engineers obtain dependable test data.
Many electronic products require continuous monitoring during environmental testing. The TH-50 is equipped with specially designed cable ports that allow power lines, thermocouples, sensors, and data acquisition cables to enter the chamber without affecting sealing performance. This design enables engineers to monitor operating parameters throughout the test while maintaining stable environmental conditions inside the chamber.
Frequent sample replacement is common during product development and validation. The TH-50 features a practical front-opening door and an optimized chamber layout that simplifies specimen loading and unloading. Engineers can quickly place test samples, adjust fixtures, and remove products after testing, reducing preparation time and increasing overall laboratory productivity.
Unlike large environmental chambers that require dedicated installation areas, the TH-50 is designed for laboratories where space is limited. Its compact footprint allows it to be installed beside workstations, in research laboratories, or within electronics development departments. This makes environmental testing more accessible and reduces the need to move samples between different locations.
The chamber is equipped with a 7-inch color touchscreen controller that supports up to 120 programmable test profiles with 100 steps per program. Engineers can create temperature cycling, humidity aging, and combined environmental test sequences through a simple interface. Ethernet communication and USB data export functions provide convenient access to test records, helping laboratories improve documentation, traceability, and quality management processes.
Intel valued the TH-50 not only for its environmental performance but also for its suitability in daily laboratory operations. The combination of precise control, compact size, programmable testing capabilities, and convenient sample access allows engineers to conduct qualification testing, reliability verification, and product development projects more efficiently. This helps accelerate testing schedules while maintaining compliance with internationally recognized environmental testing standards.
