SPECIALITY/CUSTOM
RAIN & SPRAY TEST CHAMBER
ESPEC makes rain and spray testing easier by offering a standard chamber capable of published and OEM proprietary test methods.
The standardized design can be configured for the rain/spray tests you need, eliminating the guesswork in buying a chamber. The system is based on the IP and SAE specification requirements used for electronics, enclosures, and automotive parts.
SETTLING DUST CHAMBER
ESPEC dust chambers provide a low-mess solution to common settling dust test requirements for automotive components and electronics cabinets. Our deep W-shaped hopper provides better collection and dispersion dust without needing a vibration unit to shake the dust to the bottom of the collector.
These chambers have a unique clamshell lid for easier, cleaner loading, compared with traditional top-loading designs. Optional reach-in glove ports allow rotating the test sample without opening the door.
The touch screen controller allows setting the duration of the agitation, the settling time of the dust, and the overall test time. The optional underpressure vacuum is also managed from the controller.
