Constant temperature and humidity testing machine is also called environment testing machine, used to test various types of materials for their tolerances of heat, cold, dry, humidity.Application: Quality inspection for all types of electronic products, electric appliance, and products from communication, instrument, automobile, plastic, metal, food, chemical, building materials, medical and aerospace industries.
Features
- Graceful appearance, circularly shaped body, surface treated with mist strips, and plane handle with no reaction. easy to operate, safe and reliable.
- Rectangular double-glassed watching window for the observation of the test products during the testing process. the window is 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.
- Double-layer-insulated airtight doors, able to insulate the internal temperature effectively
- Water supply system that is externally connectable, convenient for refilling water into the humidifying pot and automatically recyclable.
- The France¡¯s "Taikang" brand is used for the circulation system of the compressor, capable of removing the lubricant between the condensation pipes and capillaries. The environment-protecting coolant is used for the whole series (R23/R404/R507).
- Imported LCD display screen is used for the control unit, capable of displaying the measured value as well as the set value and time.
- The control unit has the functions of multiple segment program editing, and of quick or slope control of temperature and humidity.
- Inserted mobile pulley, convenient for movement and relocation, with strong positioning screws.
