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.
Main Features
1,Appearance: high-texture appearance, arc shape body, and matte fringe processing of surface, planar non-reactive handles, easy operation, safe and reliable.
2,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.
3,Water supply system: with external connected water supply system, convenient to humidification and water supply, and automatic recycling and use.
4,Compressor: Compressor circulation system adopts French "Tecumseh" Brand, it is more effective to remove condenser tube and capillary lubricants, and full ranges of series adopt environmental refrigerants (R404,507)
5,Control Mode: adopt smart PID+SSR/SCR forward and inverse two-way synchronization output, containing advanced slope control logic.
6,Controller: with multi-stage program editing, and temperature and humidity can be made quick (QUICK) or slope (SLOP) control.
7,System Capacity: can login 150 group of programs x 1500 sections, sections can be divided freely, program can be interrelated freely.
8,Circulation Setting: can operate 9999x999 times circulation, and can be divided 5 groups of independent part circulation.
9,Time Signal: 3 groups of sequence control output interface, with 10 kinds of time control mode, convenient to operate START/STOP sequence plan of external drive component.
10,Safety Detector: 15 items of full-function system detects, ensure the safety of machine operation, and can automatic display failure time, items and resolved method.
