Feature of constant Temperature and Humidity Test Chamber HD-E702:
- HD-E702 temperature and humidity test chamber can quickly and accurately simulate various indexes of constant temperature and humidity climate. It is used to test the performance of products that need temperature test (-40℃~+150℃), humidity test (20~98%RH) or temperature and humidity test at the same time. The capacity of the chamber can be customized.
- HD-E702 environmental test chamber, also known as constant temperature and humidity chamber, is designed to test the performance of materials in various environmental testing equipment and various material holding tests, cooling tests, heating tests, wet tests and drying tests, etc. Suitable for product quality testing purposes such as electronics, electricity, communications, measuring instruments, vehicles, plastic products, metals, food, chemicals, building materials, medical, aerospace, etc. Haida temperature and humidity test chamber, made of durable stainless steel, ensures accurate environmental simulation. It supports customers in testing product reliability and stability, improving quality assurance.
- Energy-saving refrigeration system with expansion valve system.
- Precise humidity control (including low temperature and low humidity control).
- RS-232/485 communication with dedicated software.
- power source
- According to EU regulations, the approved gas is optional gas, refrigerant type R449A and R508B.
- Internal size can be customized
