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.

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.
