Thermal Shock Chamber

NSW-152-TSC

APPLICATION
NSW India climatic chambers are a great choice for cyclic low, high temperature and humidity tests. Built with the highest quality and reliability, this chamber can meet the most stringent testing needs of various international standards such as ASTM, IEC, MIL, DIN, etc. NSW climatic chamber are designed for simulating, monitoring to control environment conditions. These chambers are double walled and modular in construction, easy to assemble at site. Size of chamber can be made as per customer requirement. Air circulation is made to create uniform temperature under RH inside. NSW climatic chamber are used to carry out various climatic tests such as condensation free temperature cyclic, hot storage /cold storage test at different temperature which may be fixed or variable.

We just wanted to let you know how impressed we've been with your assistance in the selection, purchasing process right through the manufacturing of the recent equipment we purchased from your company.
George Watson
The oven has arrived in one piece and that's good, even better we've positioned, wired, plumbed and gave her a test spin this afternoon and all looks good.
Mark T.
We are very impressed with their high precision temperature controlled equipment and wish them a very bright future ahead. We received best quality Industrial Ovens and Furnaces from their Company.
