LIB recently welcomed a customer delegation from Egypt to conduct the Factory Acceptance Test (FAT) for four
environmental test chambers designed for household appliance reliability testing. The order included two temperature and humidity test chambers and two salt spray test chambers.
Throughout the acceptance process, the customer team carried out a comprehensive evaluation of equipment performance, operational functionality, safety systems, and communication capabilities to ensure the chambers fully met their testing requirements.
To verify temperature performance across the full operating range, the chambers were tested from +150°C down to -40°C. Thermal compensation tests were also performed at 0°C and 50°C, confirming excellent temperature uniformity, stability, and control accuracy.
In addition, the customer inspected the integrated safety protection systems and validated USB and Ethernet communication functions, ensuring reliable operation and convenient data management.
For the salt spray chambers, temperature performance within the test chamber and saturated air barrel was carefully verified. Spray collection rates were measured to confirm compliance with testing requirements, while the automatic solution stirring system was tested to ensure stable and continuous operation throughout long-duration corrosion tests.
The customer also reviewed the safety protection features and communication functions, confirming the chambers were ready for efficient and reliable testing applications.
Following the successful acceptance process, the customer expressed satisfaction with the equipment performance and manufacturing quality. The visit further strengthened cooperation between LIB and the Egyptian customer as they prepare for future testing projects.

LIB's Temperature & Humidity Test Chamber is engineered to deliver highly accurate and repeatable environmental conditions for product reliability testing. Featuring a temperature range from -40°C to +150°C and precise humidity control, the chamber maintains exceptional stability throughout the test cycle. Advanced sensing technology combined with an optimized airflow distribution system minimizes temperature fluctuations and ensures uniform conditions throughout the workspace, providing confidence in every test result.
Whether performing product qualification, thermal stress analysis, accelerated aging studies, or quality verification, the chamber offers the flexibility required by modern laboratories. The spacious test area can be configured with adjustable shelves to accommodate samples of different sizes and shapes. Multiple access ports allow easy integration of thermocouples, sensors, cables, and auxiliary equipment, making the chamber suitable for testing electronics, automotive components, consumer products, materials, and industrial assemblies.
Designed with laboratory efficiency in mind, the chamber features an intuitive touchscreen controller that simplifies test setup, monitoring, and data management. Users can create and save multiple testing programs, schedule complex temperature and humidity profiles, and view operating status in real time. The large observation window, bright LED interior lighting, and durable door sealing system provide convenient sample monitoring while helping maintain stable chamber conditions throughout the test process.
Energy efficiency is integrated into every aspect of the chamber design. Intelligent humidity management technology reduces water consumption while maintaining precise control, and high-efficiency insulation minimizes heat loss during operation. Variable-speed refrigeration and airflow systems optimize energy use according to testing demand, helping laboratories reduce operating expenses. Low-noise performance further enhances the working environment, allowing engineers and technicians to work comfortably even during extended testing periods.
Constructed with high-quality components and corrosion-resistant materials, the chamber is designed for continuous operation in demanding laboratory and production environments. Comprehensive safety protections safeguard both the equipment and test specimens, while the robust design helps ensure long service life, minimal downtime, and reliable performance year after year.
The LIB Salt Spray Test Chamber delivers stable and homogeneous salt mist conditions in accordance with ISO 9227 testing requirements, including NSS, AASS, and CASS procedures. Equipped with high-precision PT100 temperature sensors and an advanced PID control system, it maintains exceptional temperature consistency throughout the test cycle. Optimized spray towers and durable quartz atomizing nozzles ensure uniform salt deposition across all specimens, providing dependable corrosion resistance data for metals, surface coatings, and plated components.
Engineered for continuous operation, the chamber features automatic water replenishment, low-water protection, and condensate recovery functions that reduce operator workload. The intuitive touchscreen controller supports multiple languages and allows users to create and store extensive testing programs. Integrated data recording, USB and Ethernet connectivity, and automatic alarm notifications simplify documentation and help laboratories maintain complete traceability of test results.
Manufactured from corrosion-resistant materials, the chamber is built to withstand prolonged exposure to aggressive salt environments. The transparent sloped lid minimizes condensate dripping onto test specimens while providing clear visibility during operation. Precision monitoring components, smooth interior surfaces, and mobile caster wheels contribute to straightforward maintenance, easy cleaning, and dependable performance over years of service.
A variety of sample holders are available to accommodate different specimen dimensions and geometries. Removable racks facilitate quick loading and unloading, while flexible program management enables users to combine multiple corrosion testing methods within a single automated cycle. This versatility allows laboratories to efficiently evaluate a broad range of products and materials.
During a recent Factory Acceptance Test, a customer from Egypt evaluated four environmental test chambers supplied by LIB, including two Temperature & Humidity Chambers and two Salt Spray Chambers intended for household appliance testing. Comprehensive assessments covering low-temperature capability, temperature uniformity, salt fog distribution, and operational safety demonstrated the systems’ strong performance and reliability. The customer expressed high confidence in the equipment quality and indicated plans to expand cooperation with future purchases.
