Recently, LIB's technical service team successfully visited a Vietnamese customer to provide professional maintenance training and preventive inspection services for their Temperature and Humidity Test Chamber. The visit strengthened the cooperation between both companies and ensured the chamber continues to deliver highly accurate, reliable, and stable environmental testing performance for years to come.
The Vietnamese customer utilizes the chamber for product reliability verification, quality control, and environmental simulation testing. Through on-site maintenance training, LIB engineers helped operators better understand daily operation procedures, preventive maintenance methods, troubleshooting techniques, and performance optimization practices.
【LIB Provides Comprehensive Temperature and Humidity Chamber Maintenance
Training】
During the visit, LIB engineers conducted a complete inspection of the customer's Temperature and Humidity Test Chamber and delivered detailed technical training.
High-Precision Temperature and Humidity Performance
The chamber is equipped with PT100 Class A temperature sensors and high-accuracy humidity sensors, delivering temperature stability of ±0.5°C, temperature uniformity within ±1.5°C, and humidity accuracy of ±2.5% RH. During the maintenance visit, LIB engineers verified the chamber's operating performance and confirmed that it continued to provide stable and repeatable environmental conditions. These capabilities allow the customer to conduct long-term reliability testing with confidence while maintaining consistent compliance with internal quality and performance requirements.
Chamber Structure Inspection and Preventive Maintenance
As part of the on-site service, LIB engineers performed a comprehensive inspection of the chamber's refrigeration system, air circulation system, humidification system, electrical control cabinet, door sealing components, and safety protection devices. Preventive maintenance procedures were demonstrated directly to the customer's technical team, including filter cleaning, water system inspection, sensor verification, and parameter calibration. These routine maintenance practices help extend equipment life, reduce unexpected downtime, and ensure long-term testing accuracy.
Practical Operation Training
To help the customer maximize equipment performance and service life, LIB provided hands-on operational training focused on daily use and routine management. The training covered startup and shutdown procedures, test program creation and modification, alarm diagnosis, troubleshooting techniques, data monitoring, and long-term chamber preservation
methods. Engineers also demonstrated how to efficiently use the color touchscreen controller, which can store up to 120 test programs with 100 steps each, making complex environmental testing procedures easier to manage and execute.
Reliable Testing for Diverse Applications
The customer's Temperature and Humidity Test Chamber is used for a variety of product reliability and environmental simulation tests. Applications include electronics reliability testing, automotive component validation, material aging studies, industrial product qualification, and Environmental Stress Screening (ESS). By accurately controlling temperature and humidity conditions, the chamber enables the customer to reproduce real-world environmental stresses and meet the requirements of international testing standards as well as customer-specific testing protocols.
