Laboratory environments often store sensors, reference standards, electronic instruments, optics, and calibration equipment that can be affected by humidity. Controlled low-humidity storage helps reduce corrosion, oxidation, contamination risk, and environmental variability. Dry cabinets provide a repeatable storage environment between use cycles and are especially valuable for infrequently used but high-value laboratory assets. Laboratories should consider humidity control as part of their quality system rather than simply a storage convenience.
