WALK-IN STABILITY CHAMBERS are designed for simulating, monitoring & control of environmental conditions like temperature & humidity. All these chambers are medium to large-sized chambers that are custom-built double walled & modular in construction, easy to assemble at site. They are available in standard sizes & can also be tailor made to suit specific requirements. Walk-in Stability Chambers are perfectly designed for the high requirements of stability studies and climatic tests. These Chambers repeatedly produces required conditions, structural integrity that keeps the chamber working properly through years of demanding test cycles. This has also led to huge load reduction on the heating, cooling & humidifier systems.

Walk-in Stability Chambers are designed for testing of electronic, electrical components, corrosion studies on mechanical parts, shelf life studies on paints, in Pharmaceutical & Packaging sector & Other Q/C Labs, varnishes and cement at respective manufacturing facilities.
