YL-2236 Programmable Constant Temperature and Humidity Tester

Purpose:
Constant temperature and humidity tester, as know as environmental testing machine, test various materials for their heat resistance, cold resistance, dry resistance, humidity resistance performance; suitable for electronics, electrical appliance, food, vehicles, metals, chemicals, building materials, bags, adhesive, printing, packing and other factories quality control purposes.


◆ Appearance: high-texture appearance, arc shape body, and matte fringe processing of surface, planar non-reactive handles, easy operation, safe and reliable.


◆View window: rectangle complex layers of glass view window can be used for observation specimen when doing testing. With anti-sweat heater unit of the window can prevent water vapor condensing water droplets, and high-brightness PL fluorescent lamp keeps box lighting.


◆Water supply system: with external connected water supply system, convenient to humidification and water supply, and automatic recycling and use.
