Fast change rates testing chamber is suitable for testing the changes of instruments,electrical,electronic products,machine and parts under the rapid temperature change or the the gradient conditions, takes advantage of compact, modern scroll compressors to bring fast temperature cycling to small form factor. Temperature cycling rates from 5 to 20°C/min. are possible. Two different ultimate low temperatures are available: -40°C or -70°C.
The faster cycle times can be used to meet more aggressive test methods that require thermal stress during transitions. Significant test time can be saved in completing tests, as well.
To demonstrate performance, Grande uses the international standard IEC 60068 3-5 measured at the supply air. Temperature cycles are run from hot to cold extremes, and the middle 80% of the transition is timed to determine performance. Your actual cycling results will vary depending on methodology, including the start and end temperatures, and the amount of samples loaded.

RECOMMENDED OPTIONS
Dry air purge, to compensate for quickly shrinking air during cooling, as well as to reduce risk of condensation.
Product temperature control, allows feedback from a second sensor on the product. Ensures faster completion of transition steps.
