Precision Rapid Temperature Ramp. Rate Test Chamber
10C/min Energy Saving Fire Resistant Humidity Control for Automotive
Sanwood environmental stress screening test chamber, also name as rapid temperature change rate test chamber, ESS chamber, is to change the external environmental stress by using the temperature acceleration technique (the product produces alternating expansion and contraction when circulating in the upper and lower extreme temperatures) under the design strength limit, so as to generate thermal stress and strain in the product.
Through accelerated stress to underlie the drawbacks of products emerge [potential parts material defects, process defect, process defects], in order to avoid the product in use process, by the test of environmental stress and sometimes lead to failure, cause unnecessary loss, to improve the product yield and reduce delivery times has a significant effect of repair, additional stress screen itself is a kind of process stages of the process, rather than as a reliability test, so the stress screening is 100% to the application of products

Rapid Temperature Change Test Chamber / ESS Chamber features:
1.Graceful appearance, circularly shaped body, surface treated with mist strips, and plane handle with no reaction.
Easy to operate, safe and reliable.
2. Rectangular viewing window for the observation of product under test, equipped with sweat-proof electrical heating device that can prevent water steam from condensing into droplets, and with high brightness PL fluorescent bulbs to provide light inside the box.
3.Double-layer-insulated airtight doors, able to insulate the internal temperature effectively.
4.Water supply system that is externally connectable, convenient for refilling water into the humidifying pot and automatically recyclable.
5. French Tecumseh is used for the compressor circulation system, capable of removing the lubricant between thecondensation pipes and capillaries. environment friendly coolant is (R23,R404A)
6.LCD display screen is used for the control unit, capable of displaying the measured value as well as the set value and time.
7. The control unit has the functions of multiples segment program editing, and with temperature ramp
8. Casters for ease of mobility, with strong positioning screws.
