This guide regulates the daily start-up/shut-down, parameter setting, sample loading, process monitoring and maintenance of laboratory constant-temperature and humidity test chambers (hereafter “the chamber”), ensuring personnel safety, equipment reliability and data traceability.

After long-term use, components or systems of a high-low temperature and humidity test chamber may encounter certain issues.

In modern industrial practices, evaluating material corrosion resistance has become a critical quality control procedure. As the core testing equipment, salt spray chambers simulate various environmental parameters to deliver four distinctive testing modalities:

A constant temperature and humidity test chamber is an instrument used to test objects under specific temperature and humidity conditions.

Temperature is the most fundamental—and most brutal—physical parameter influencing the reliability of materials, components and complete systems. GB/T 2423.1, GB/T 2423.2, GJB 150.3A, GJB 150.4A, DO-160 Section 4/5, IEC 60068-2-1/-2 and MIL-STD-810H all quantify requirements for temperature slew rate, dwell time, heat load and measurement uncertainty.
