Temperature Cycling Test Chambers Fast change rates test chamber Temperature Cycle Test Chamber 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.

Liquid Thermal shock test chamber Three Zone Thermal Shock Test Chamber Thermal Shock Test Chamber Liquid Thermal Shock Test Chamber,Cold and hot impact machine can be used to test material structure or composite material, in an instant by extremely high temperature and extremely low temperature continuous environment can endure degree, in order to in the shortest time test commits any heat bilges cold shrink caused by the chemical changes or physical damage. Applicable objects including metal, plastic, rubber, electronics, pv, solar... And other materials, the products can be used as a basis of improving or reference. Significant reductions in fluid usage make liquid thermal shock affordable Purchasing a liquid thermal shock chamber needs close consideration of the long term operating costs. The specialized liquids used can easily evaporate, causing the loss of thousands of dollars of fluid per year, if not properly contained. Liquid-to-liquid thermal shock testing is typically conducted to apply very strong, repetitive thermal stress to test pieces. It can model a product's ability to withstand thermally-induced size changes, crack resistance, hermetic integrity, and changes in electrical properties. This form of testing provides a very rapid temperature shock recovery of conditions, and it can significantly reduce testing time by requiring shorter soaks and less cycles. The liquid thermal shock chambers have been built to meet the demanding test requirements, which has become a defacto industrial standard for semiconductor devices.

Salt corrosion spray test chamber Configured for your specific tests Alternate Salt Corrosion Spray Test Chamber Grande makes rain and spray testing easier by offering a standard chamber capable of published and OEM proprietary test methods. The standardized design can be configured for the rain/spray tests you need, eliminating the guesswork in buying a chamber. The system is based on the specification requirements, and can also accomplish individual automakers tests, as well as electrical-enclosure tests. Our Design Grande's modular design allows you to add on additional features, depending on the number and type of tests required. One possible choice is to integrate the spray system with a regular temperature and humidity chamber to save money and floor space, while also creating an opportunity to simulate actual operating conditions your product may experience. Our system uses multiple control solenoids to vary the water's spray volume/pressure. A holding tank prepares the water to the desired temperature, if required. A pump ensures the water is delivered in the proper pressure range. The water is fed to a motorized manifold that rotates the spray arms. Each spray arm has an adjustable valve to allow finer control of the spray. Testing capabilities The specification is modeled after and doesnt differ greatly. Details about the nozzle types and the rotating nature of the spray arms and product table are also included in the requirements. Additionally, drip and car wash tests are also specified.
