NPD Conditioning Chamber
Model: NPD-252 | Precision Temperature & Humidity Testing System | NPD-CC Series
An advanced environmental testing system engineered for precise and repeatable temperature and humidity conditions. Suitable for preconditioning, stability studies, accelerated ageing and material-behaviour analysis across research and industrial applications.
Reliable Climatic Conditioning for Demanding Tests
The NPD Conditioning Chamber combines accurate temperature control, advanced ultrasonic humidification, forced air circulation and programmable multi-cycle operation to maintain stable test environments. It helps evaluate how materials and products respond to thermal extremes, moisture exposure and combined climatic conditions over prolonged periods.
The chamber is designed to support testing consistent with internationally recognised IEC 60068 methodologies, including damp-heat steady-state and temperature-humidity cyclic methods. Suitability for a specific test standard should be verified against the selected configuration and test protocol.
