The hot and cold chamber has a very simple process of working. The instrument is equipped with two chambers that simulate extreme hot & cold temperatures with the inculcation of SSR-based & highly advanced heaters along with blowers & fans for uniformity. On the contrary, the cold chamber is equipped with conditioners that replicate extremely cold weather conditions around the specimen and assess the change in its properties.

The price of Hot and Cold chamber can differ from 5lacs to 70 lacs in India depending upon the industry it is catering to as the sizes of batteries differ largely in variable industries. For example, the size of a battery used in the automobile sector is way bigger than the size of a battery used in the mobile phone sector.

To get our hands on a verified instrument, it is highly important to make sure that you adhere to all the specifications listed about the instrument and compare them with the guidelines of the designated standards. If both specifications and standard compliances aligns with each other, the chances of the instrument being verified increase.
