Temperature and Humidity Test Chamber LHL-120-B/LHL-120-C/LHL-120-E, 120 L (CAT#: STEM-AL2-5268-ZJF)

The Temperature and Humidity Test Chamber LHL-120-B is a controlled-environment laboratory system designed for temperature and humidity cycling tests. The enclosed workspace maintains defined environmental conditions around samples during extended test or culture periods. Temperature regulation controls the internal environment according to the operating range stated for the configuration. Humidity, illumination, gas composition, or refrigeration functions are provided when specified for the individual model. Air circulation and sensing components distribute and monitor the controlled conditions within the chamber. The control system supports fixed or programmed operation according to the features listed in the source data. Internal shelves or work surfaces organize samples while the enclosure reduces exposure to changing room conditions. The system is suitable for repeatable laboratory workflows that require controlled environmental conditions.
