Quality is more than a word HAST Chamber)

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.

Utility Improved functionality and ease-of-use for bias testing. 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) Chamber interior The units are designed so that the test condition of each chamber can be set individually, enabling this model to effectively reproduce diverse test...

Utility 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...

Control operation Complies with IEC60068-2-66 standard testing while maintaining compatibility with conventional test methods Conforms to international IEC60068-2-66 standard IEC60068-2-66 is an environmental testing standard of the IEC (International Electro-technical Commission). With ESPEC's unique wet and dry bulb temperature control function, the EHS Series meets all requirements for test equipment and test operation specified in IEC60068-2-66. The EHS Series can also satisfy other test conditions of EIAJED 4701, JEDEC and EIA/ JESD22-A110-A as well as IEC. * ESPEC was directly...

Control operation M type: Wet and dry bulb temperature control Unsaturated control Wet saturated control Standard type: Unsaturated control Wet saturated control Control functions to enable use of previous data The control mode can be switched to match previous data. Three modes of operation control Wet and dry bulb temperature control (M type) Chamber pressure Test period 0.010MPa (Gauge) Exhaust valve opened Chamber temperature before and after testing can be controlled. In hold process Gradient pressure reaches 0.010MPa (Gauge), only air humidity inside the chamber are maintained at...
