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 HAST chamber series offers high performance, functionality and ease of use, and is compliant with the international IEC60068-2-66 standard. Many convenient functions and safety features are included for bias testing.
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 accurate temperature and humidity control over the entire process, from before testing to the post-testing temperature decrease or hold process. After testing is complete, both 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 door is opened and specimens are removed. This makes it possible to place a specimen in a constantly controlled temperature/humidity environment, and keep it from drying after returning to atmospheric pressure.
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 will be automatically taken from a water tank. A viewing point on the front side allows the remaining amount of water in the tank to be checked at a glance.
Protection measures for specimen
Standard equipment includes a specimen power supply control terminal, which outputs contact signals to allow voltage and signals to be applied to the specimen during testing. When a problem occurs, specimens and chamber are fully protected. Power supply to the specimen is halted, and protection mechanisms for preventing overheating and boil-dry are activated.
