Temp humidity and vibration compatible Chambers
Vibration Test Chamber
Industrial-quality chambers for combination testing with vibration systems
For years Temp.humidity and vibration compatible Chambers have been the workhorses of the environmental test chamber industry. Originally created to meet military test standards, their flexible design has made them suitable for a wide variety of applications. Fast temperature changes of5 to 25C/m. are possible, even with significant loads. The chambers have a removable floor, allowing integration with vibration test systems. Custom designs are common, allowing configuration to meet your exact requirements.
Special model can interface with both vertical and horizontal vibration systems
In addition, the�touch-screen controller�makes running an Grande environmental test chamber a breeze. The full-color, touch-screen interface is remarkably easy to use and understand. The Touch Screen Controller�can be managed remotely via our new�Ethernet/LAN-based Web Controller, serial port, or GP-IB/Lab View.

Grande Expertise in Humidity Control
Controlling humidity in a small environmental chamber can be especially challenging. Grande expertise in humidity control brings intelligent design that is carefully integrated into the Criterion chambers. The humidity subsystems are designed for reliability, convenience, and performance:
An external steam generator allows expanded range and is easy to maintain.
A separate de-humidification coil improves low humidity control and range.
Wet-bulb humidity sensor is a �??primary measurement method�?? for accuracy. It is also economical, easy to maintain, and reliable because it has no risk of failure due to over-saturation. (Read why analog is preferred over digital.)
Direct water supply connection is standard, with options for water filtering and recirculating water tank.

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 req uirements, which has become a defacto industrial standard for semiconductor devices.

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.
