‚P Creates temperature, humidity, and pressure environments to IEC60068-2-66 standard. Humidity resistance evaluation tests for electronic components Customers require test results that correlate accurately to those from the field in a minimal amount of time. The Highly Accelerated Stress Test Chamber EHS Series offer high performance, functionality and ease of use, and are compliant with the international IEC60068-2-66 standard. Many convenient functions and safety features are included for bias testing.

‚R The chamber interior is formed for easier specimen loading The pressure vessel is of spherical form which distributes pressure evenly and has superior strength. The test area is expanded to its maximum size to easily load printed circuit boards and other specimens. The double stage model answers the need for diverse test conditions and large capacity (MD type) The units are designed so that the test condition of each chamber can be set individually, enabling this model to effectively reproduce diverse test conditions on a large number of specimens. Specimen signal terminals can be added...

‚S Even greater convenience and safety. Easy program setting Program capacity of 10 patterns with 30 steps per pattern. Simple operation using up and down keys for program setting, as well as adjustment of temperature, humidity and time values. Safe and reliable door The system employs a button operated automatic door locking mechanism. It prevents the door from being opened while the test chamber is pressurized. Automatic humidifying water supply system At the start of testing, the humidifying water needed for that test is automatically taken from a water tank. A slit on the front side...

‚T Wet and dry bulb temperature control (M type) conforms to IEC60068-2-66 standard With ESPEC's unique wet and dry bulb temperature control on M type chamber, temperature and humidity are measured directly using a wet and dry bulb temperature sensor. This ensures highly precise temperature and humidity control over the entire testing process, from before testing to the post-testing temperature decrease or hold process. After testing is complete, the temperature and humidity are allowed to drop for a fixed period. In the hold process, the chamber is kept at a fixed environment until the...
