IEC 62368-1 Clause 4.1.4 Programmable Constant Temperature And Humidity Test Chamber
Product information:
This programmable temperature chamber is required by IEC 62368-1:2018 clause 4.1.4, Y4.4, Y6.2, etc.
This test chamber is used for cold, heat, humidity and dryness testing of raw materials and devices such as electronics, electricians, electrical appliances, plastics, etc. The purpose is to confirm the products reliability of storage and transportation under high and low temperature alternating heat and humidity.
It conforms to standards:
IEC60068-2-1:2007 “Environmental Testing-Part 2-1: Tests-Test A: Cold, IDT”
IEC60068-2-2:2007 “Environmental Testing-Part 2-1: Tests- Test B-Dry heat, IDT”
IEC60068-2-78:2012 “Environmental Testing-Part 2-78: Tests-Test Cab: Damp heat, steady state, IDT”
IEC60068-2-30:2005 “Environmental Testing-Part 2-30: Tests-Test Db: Damp heat, cyclic (12h+12h cycle), IDT”
Features:
1. The test system has advanced and reasonable structural design,
standardized manufacturing process, beautiful appearance and
generous appearance.
2. The main functional components of the test chamber are world
famous branded ones. The test chamber has best control of noise and
energy saving.
3. The matching of components and assembly is good. The main
functional components are imported from the internationally branded
companies, which improves the safety and reliability of the test
chamber, and can ensure the long-term, high-frequency usage
purposes.
4. The equipment has good operability, maintainability, good
temperature stability and durability, good safety performance. It does not pollute the
environment and endanger human health.
